I welcome you friends, my name is Sergey,00:00:02
we continue to study the00:00:03
C sharp programming language,00:00:04
today's topic of our lesson is the00:00:06
conditional cash operator, let's find out what it is, why it is00:00:09
needed and how it is used in this00:00:11
lesson, we will have a fairly simple00:00:13
example based on what we have studied so far00:00:15
more complex based on00:00:16
object-oriented00:00:17
programming and, let's say, using an example00:00:20
that is quite00:00:22
common in real applications,00:00:23
it may be difficult for you to understand the second00:00:26
part of this lesson,00:00:27
however, I think that it is worth00:00:29
posting here because this is a typical00:00:31
example of using this operator00:00:32
in any case in the future you can always00:00:35
come back and watch this lesson again00:00:37
in order to refresh your knowledge about00:00:39
this operator, don’t forget to subscribe00:00:41
to the channel and hit the bell so as not to00:00:43
miss the next lessons, but now let’s get straight00:00:44
to the point, first00:00:46
let’s look at the situation when we generally00:00:49
need to use a00:00:50
conditional cash operator By the way, he looks like this:00:00:54
question marks. so we have a00:00:58
certain method that returns us acer00:01:01
in this case, this is a simple example of a00:01:03
maser end of as I already said, it can00:01:05
be absolutely any information, an array of00:01:08
anything, and this00:01:09
information can be requested from the database to00:01:11
some kind of cross luck -00:01:13
in this case, we have ggt00:01:19
paradise as a stub for such a request and in its current implementation it will00:01:22
return us an array of three elements where00:01:24
we will store the numbers one two and three00:01:26
for 24 lines of code in we call the data00:01:30
method and in a variable r and get its00:01:32
result in the future, in 24 lines of00:01:34
code we calculate the sum of the elements of this00:01:37
array using the extension method itself,00:01:39
if we run this now, then everything00:01:41
works well without problems, but as I already00:01:44
said, this hetero method is a00:01:47
stub and emulates the situation when we00:01:49
receive this information from some00:01:50
external source, there is00:01:52
a possibility that from an external source,00:01:53
instead of real data in our array, we00:01:56
will receive cash in this case, if we00:01:57
run our program we get an00:01:59
exception, let's find out in more00:02:01
detail why we received this exception00:02:03
on 24 lines of code in us00:02:05
break point we launch the debugger using the00:02:08
f5 key, using the f10 key00:02:11
we take a step and we see that in our00:02:13
array we now knew because the00:02:15
hetero method returned us instead of real00:02:17
data, well that’s why in this case on the00:02:20
twenty-sixth line of code where we have00:02:22
the output in console, we are trying to access00:02:24
objects and the roar of the variable may fish,00:02:26
call its method itself so that it00:02:29
calculates the sum of alimony of all arrays,00:02:31
how can it do this if we are00:02:34
now again remembering the lesson on reference00:02:36
and value types and we understand that we00:02:39
actually have a shortcut which does not refer00:02:42
to the real data in the heap,00:02:44
respectively, we are trying to add00:02:46
some elements that do not exist00:02:49
because we have no power with the00:02:50
elements in reality, we only have00:02:52
a label that is not assigned a reference to the00:02:54
data of the managed heap, responsibly00:02:57
trying to do this we get an00:02:59
exception00:03:00
typical the situation is how we can get around00:03:02
this by performing a check on the cash of our00:03:05
array,00:03:06
if dismal is allowed then we will00:03:08
display messages crazy to the element of the00:03:10
array mart let's say then because00:03:15
we don't have a lot of any elements otherwise00:03:18
we actually execute our code in this00:03:21
case we won't get an exception00:03:23
because we check this whole thing for cash and00:03:25
if we have now added all this,00:03:27
we run a check for tax00:03:30
and execute exactly that branch where we do not00:03:32
access arrays which are a lot, we00:03:33
simply display a message that the sum of the00:03:36
elements of the array is 0, we move on as00:03:38
you can see,00:03:40
the dimension of our code and we are00:03:43
understandably not happy with this kind of thing, let’s00:03:45
roll it all back and in this case the00:03:50
conditional operator will help us, but instead of00:03:52
doing all this checking for cash,00:03:54
we are here before we access00:03:57
our array, can we put ? and further. what will now00:04:00
change during the execution of our00:04:02
program, before accessing our00:04:06
array, trying to add its elements, a00:04:09
check will be performed for on st. So,00:04:11
if at the time of calling this00:04:13
operator in our array there is no, otherwise the00:04:16
further move will not be executed,00:04:18
accordingly we do not have there will be attempts00:04:19
to add non-existent elements00:04:21
as a result of this expression if there00:04:24
was nalto in the array instead of00:04:25
executing this code, we will still be00:04:28
left here with let's run it, we always00:04:31
look at the bugs in the array right now, and00:04:33
if we execute the code on the twenty-sixth00:04:36
line of code we just get the00:04:38
message sum of array elements, but as00:04:40
you can see 0 is not there anywhere for the simple00:04:43
reason that we added a channel to this phrase sum of00:04:45
array elements, that00:04:47
is, nothing, but if there are real elements in our array00:04:50
and we run00:04:53
this code, then we will be executed and the00:04:56
array elements we will have calculated let's00:04:58
return the situation again as if in our00:05:00
array we will have00:05:02
what should we do if we still want to00:05:04
output some default value00:05:06
if you watched the previous lessons you know00:05:08
that we also have an operator for00:05:10
combining dreams and in in the lesson before last, I00:05:13
mentioned that the union operator has become00:05:16
very often used precisely with00:05:19
this operator, the00:05:21
conditional operator on, so we can00:05:24
combine them if there00:05:25
is on in our array, but this code00:05:28
will not be executed, that is, the method itself00:05:31
but instead of here this is all this is00:05:34
all that I will highlight, we will have cash,00:05:37
respectively, here we can00:05:38
use the snow union operator and00:05:41
display the default value; the only00:05:44
nuance is this expression, we need to put it in00:05:46
parentheses so that it correctly00:05:48
recognizes c when concatenating with a00:05:51
string, we run again all these types of00:05:53
bugs in array we now knew,00:05:55
respectively, this operator checks00:05:57
our array, you see what’s there on and it00:06:00
will not call the method itself, but as a00:06:02
result,00:06:03
instead of this entire expression, we00:06:06
get cash, then we have a00:06:09
union operator again, it checks this, the00:06:12
result sees something cash and substitute the00:06:14
default value 0 as a result on the00:06:17
console we receive messages the sum of the00:06:18
array elements is 0, but if in our00:06:21
mass I do not have cash and real data00:06:23
we run de bani00:06:25
well, the mass is massively three elements antami00:06:27
with this 23 what will happen in this case is00:06:30
our array will be checked with00:06:32
with the help of this operator, he sees that something is00:06:34
small for me and00:06:36
the method itself will be called responsibly, then the union operator00:06:38
again checks everything we00:06:40
got, he sees that we have the sum of00:06:42
real numbers, they accordingly, the00:06:44
default value will not be used00:06:45
and we will receive a message in the console00:06:47
about the sum of the elements of the array 6, now let's00:06:50
look at another example, a typical00:06:52
situation that will come up00:06:54
all the time when you develop00:06:56
applications in the C Cher programming language,00:06:58
we have a person class here, this is the00:07:01
same class that we used in the00:07:03
lesson before last where we showed an example of00:07:05
working with the union operator snow using00:07:08
winforms as an example, by the way, today we00:07:11
will also have approximately winforms00:07:13
if we look at the implementation of this00:07:15
class there we have three fields with00:07:17
their data from the stones moto surname first00:07:19
name patronymic and in this case we have00:07:21
added00:07:22
one more field these are the contacts of this00:07:24
person these contacts we have implemented them00:07:27
in a separate class, in this case we00:07:30
limited ourselves to a phone number and00:07:32
email. If we return directly to00:07:34
our code, we see that if we00:07:37
have created an object of the parsun class, we must00:07:39
access it through a dot to gain00:07:42
access to its contacts and then we can00:07:44
get already access to the phone number00:07:46
at each of these steps we can00:07:49
get us a reference exception each00:07:52
of the objects of this class and the object of the00:07:56
class Thorson and contracts and background Barr00:07:59
are reference types, respectively, in each00:08:03
of these fields00:08:04
everywhere in each element of this chain we00:08:06
can stumble upon a but accordingly,00:08:08
you can get it by removing the community index.00:08:10
First, let's consider a successful00:08:13
outcome of the situation. So our task is00:08:16
to get the phone number of this person00:08:19
and display it on the console. In this simple00:08:22
example, again, we are considering00:08:24
situations when we receive information about this00:08:26
person from someone from the outside the00:08:28
database and the cheeks the request does not matter,00:08:31
accordingly mine how can we00:08:33
get full information about a person and00:08:35
partial such, let’s say, in general you can00:08:38
get cash and accordingly00:08:39
turning to this field we will get a new00:08:41
francisco report in this case almost00:08:44
a stub we have again me00:08:46
to get we also set the break point ourselves, 2400:08:49
lines of code, and in this case, in this00:08:53
implementation of our stub, we actually00:08:55
get the data that we need, we00:08:57
return an object of the parson class; it has00:09:00
created an object of the compact class and,00:09:02
accordingly, it has a background set00:09:04
where we printed just such a stub00:09:06
we easily get access to00:09:08
this field, that is, the field is00:09:10
what data we have variable in the background00:09:12
barr for clarity, I’m just saving00:09:15
it separately, but in principle we could00:09:16
immediately enter the information here at the00:09:18
end, and in the future we00:09:21
’ll display this number on the console, now let’s look at it00:09:23
such a situation, we made a request to the00:09:25
database, let’s say, and instead of a real00:09:28
object of the person class,00:09:29
but it was returned to us,00:09:30
now look here we are trying to00:09:33
access the contacts field to the telephone00:09:35
number of the00:09:37
object classes by forests, but it recognized00:09:41
that is, we have the first00:09:44
process for a class object and a real one00:09:45
there is no data managed on the heap, respectively,00:09:48
if we try to access the real00:09:50
data of the person classes, for example kiva00:09:52
contact to von barr, if they are not there, we00:09:56
get friends exception dollars,00:09:57
respectively, in order to00:09:59
avoid such a situation in this case, we must00:10:02
check our00:10:04
personnel object no matter what it is small and so00:10:07
we have a Dixie class of personnel, we have00:10:09
not verified anything at all, the console,00:10:11
of course, we can compose00:10:12
some code here, let’s say write like this, there00:10:15
is no data and the case is that in our object the00:10:18
class a person00:10:19
had nothing in the possession of the data because the00:10:21
code was not executed Well, let’s00:10:23
imagine that now00:10:25
some object of the class has been returned to us, we also00:10:28
run our code without any problems and once again the00:10:31
object was a person as returned, we00:10:33
get into the body iv we access the class a00:10:35
person we do not access the contacts,00:10:37
look what we have now vkontakte00:10:40
vkontakte we have cash well, he doesn’t have00:10:42
contacts with us again we get a bang00:10:45
Fritsek inform accordingly or00:10:47
here inside you need to add one more00:10:48
and check the contacts now00:10:51
on cash and do everything like this or do it00:10:54
like this to check for the fact00:10:56
that it’s also summer in anal and contacts do not00:10:59
equal anal then we won’t need this code00:11:00
in any case, so the00:11:02
code expands and let’s move on00:11:05
now we don’t have cash in person00:11:07
and in contacts cash this code is not00:11:09
executed in the body of the if block,00:11:12
accordingly we will get the output I won’t give it away00:11:14
now let's add more contacts here, let's00:11:17
create contacts for him,00:11:18
but we don't have a phone in the contacts themselves, let's say00:11:22
we didn't write the logic phone,00:11:24
let's see what we'll have now, I think00:11:27
you already guess00:11:28
that what was filmed in the contacts, we don't have00:11:30
cash again, we end up in blocks with the00:11:34
snow brane in the background00:11:35
accordingly, here we have cash in this00:11:37
variable and we get00:11:40
nothing as output, but it’s good that the writeline method of the00:11:43
console class can work again if00:11:45
we had to do something else with this phone00:11:47
and you got another00:11:49
little reference xf in which case we need to00:11:51
add one more check and checks00:11:53
that the equestrian would also be equal,00:11:55
but thus our code keeps growing,00:11:57
growing and growing,00:11:59
to avoid all this, we can00:12:02
use the conditional operator on00:12:03
let's now do the same, but00:12:06
only with the conditional operator we00:12:08
select this extra code every moment00:12:11
where do we have the probability that we00:12:13
will receive00:12:14
we should use literature as if00:12:17
look in this case I am standing here00:12:20
in objects of the person class we will receive cash00:12:22
let's now run we have00:12:24
cash there now our conditional operator to00:12:26
check there is pita but if there is really00:12:28
cash here this whole chain that00:12:30
goes further, it will no longer be executed00:12:32
simply in the background barr nose variable with00:12:34
its own channel, and then we00:12:37
will not receive anything on the console, accordingly, since00:12:39
we have considered the situation when in00:12:41
this chain and in contacts we may be00:12:44
in on the phone itself, maybe we00:12:46
need to check the entire chain00:12:48
because if somewhere in this00:12:50
chain we have a new one, we will turn to an00:12:52
object in which but we will get a new00:12:54
refrain sex shop, respectively, if00:12:56
we let’s say there will be a situation like this00:12:58
when we later have a sannin all the00:12:59
vkontakte000:13:00
and here we do not check our00:13:02
contacts using the conditional00:13:04
science operator and here when contacting contacts00:13:05
we turn to non-existent data and00:13:08
still receive dollars france00:13:09
exception that is, in this chain teach00:13:11
here you need to add00:13:12
the operator as if in anal in this way00:13:14
it turns out as if there are some00:13:18
train cars in order to avoid a crash00:13:20
we need to follow this chain00:13:21
pro.ru we are carried out brightly by the staff00:13:24
if there is no cash then we contact00:13:27
the contacts and the00:13:29
contacts are checked on the contacts we knew00:13:32
so we won’t to00:13:33
try to access the background field on board00:13:35
because I simply does not exist and we will00:13:37
immediately place our background variable00:13:39
arr temporary value on st but as00:13:42
you can see with this implementation we do00:13:44
not get anything in output and here it makes sense to00:13:46
use the default value a for the00:13:50
dense value y we have a00:13:51
union operator knew two question marks, as I00:13:54
said, these two operators are a00:13:57
dream union operator, this operator is00:13:59
conditional in anal, this one is very often00:14:01
used together, and here we will00:14:03
write no data if we are in this entire00:14:05
chain of which we checked using the00:14:07
conditional operator in the anal00:14:09
here we never received real00:14:11
data, that is, we still00:14:12
have a small one somewhere here in this entire00:14:15
expression, then our union operator00:14:18
again looks like this, but also as a00:14:21
diffuse value we receive messages00:14:23
no data in this case in our object00:14:25
person there was information in contacts, he00:14:28
founded accordingly, further execution did00:14:29
not go after all this,00:14:32
I saw the entire operator in the cabin here again, but in this00:14:34
part of the code and assigned the background barr to the00:14:36
default value for the output, we received00:14:38
no data, too, we have initially,00:14:39
instead of an object of the class Thorsen, we will have00:14:42
everything work out in exactly the same way, well, we00:14:44
check the whole chain, if we00:14:46
have returned decals a person with contacts and a00:14:49
phone number, this whole chain of00:14:51
checks for cash will work out for us,00:14:54
then this operator sees that there is00:14:57
real data here and in the background barr we get00:15:00
5 on us board and display it on the console, and00:15:03
we used this change00:15:05
to simply clearly see00:15:06
what kind of real data we get00:15:09
after processing this entire chain; in00:15:11
fact, it is not necessary, we can do it right away like this, so we can00:15:15
learn the amount of code from us00:15:18
is reduced and we accordingly get00:15:20
all the checks we need,00:15:21
now let's look at another00:15:23
example of working with the conditional operator using the00:15:25
example found of a simple application00:15:28
that we wrote on winforms in the00:15:30
lesson before last, the task of this00:15:32
application is to display a list of not these00:15:35
characters and in the lesson before last when you00:15:37
click on the button In this lesson, we00:15:39
only received information about the last name, first name and00:15:41
patronymic. In this lesson, I added00:15:42
the ability to display contact00:15:44
information in the form of a phone number if we00:15:47
press the wound button, we have00:15:49
almost everything the same, but we just00:15:51
added the position of the background barr and as00:15:53
you can see, several characters do00:15:56
not have such a phone but one of them has a00:15:57
phone number in this case, for00:15:59
example, here it’s just a set of numbers, this is00:16:01
absolutely the same parson class that we00:16:03
just used, we00:16:05
can use leggings in the project for00:16:07
the simple reason that in this project00:16:10
we have a project connected as a reference00:16:12
lesson on wf a8 wf this is exactly00:16:16
the project information that we wrote,00:16:18
so in this project we have the same00:16:19
past class that we just00:16:21
looked at and the only difference is that we00:16:23
need to add an additional contact field,00:16:25
here we can contain a telephone00:16:28
e- mail but email and in this case00:16:30
without using only a00:16:31
telephone number and here it is the parsun class itself,00:16:36
we added in addition to the get full name method00:16:38
which we used in00:16:40
the lesson before last to display information here we00:16:42
will not look again here nothing has00:16:44
changed we have not yet added a package in the00:16:46
background barr and here in this method the dialing guide00:16:48
actually performs the00:16:50
same checks using the00:16:52
conditional cash operator, this is done for the00:16:54
same reason because if we00:16:56
assume we receive a list of objects of the00:16:58
flank class from somewhere outside and it is not a fact that there00:17:01
will be contacts there and it’s not a fact that there00:17:03
will be a phone number in the contacts;00:17:04
perhaps there will only be an email or00:17:06
nothing at all, respectively,00:17:08
all these checks are implemented in00:17:10
our attacked, this is Jason Barn,00:17:12
which returns us the string that00:17:14
is formed by the communication background bar and,00:17:15
accordingly,00:17:17
the same phone number if you have00:17:19
if it is not there, then the00:17:21
entry no data will be returned as the default value. The00:17:23
operating logic is absolutely exactly the00:17:25
same as00:17:26
what we used here, but00:17:28
only here it will be said so in a more00:17:30
specific example, let’s00:17:32
look again at the logic that00:17:34
works for us when we click on the wound button.00:17:37
we have some small changes, but00:17:39
first of all it will come out, the chance that00:17:41
the list of people returns us is our stub, we00:17:43
modified it in that for one of00:17:45
them we add another contact, so00:17:47
we have a certain one, but it is which we don’t00:17:49
know, a set object is created for it00:17:52
and the price adds to the more set,00:17:54
respectively, some people00:17:56
have a phone number and others don’t. The00:17:58
experience of these three, firstly, the contact field00:18:01
will be small and, accordingly, there00:18:03
will be no phone number there, well out00:18:05
to 4 will be accordingly, which is why00:18:08
we need this check if we have00:18:10
no contacts at all or no00:18:12
phone number, then00:18:14
we will display the message00:18:16
no data, and we have slightly00:18:19
modified the output of these same messages00:18:21
in the listbox. This is where we iterate through00:18:24
the list of all elements of the torso type and00:18:28
call the get method for each of them full00:18:31
name and in addition to this, we call get phone00:18:34
number, respectively, under get background and they00:18:37
form a record of the surname, first name and00:18:40
patronymic, and then we returned00:18:42
the look with the background barr and these are the00:18:44
results that are returned by 2 of these00:18:46
methods, we form them into a separate00:18:47
line through a separator, respectively,00:18:49
thanks to this we we get this00:18:52
list of further lessons, we will00:18:53
look in more detail at desktop00:18:55
development, including on winforms, and the00:18:57
entire source code of all the examples that00:18:59
we considered today for00:19:01
channel patrons with access to the source code00:19:03
will be available for lunch and don’t00:19:05
