The compiler guarantees that no user-overloaded equality operator == is invoked when expression x is null is evaluated.
I do this kind of thing with lists or arrays. If you emanet enumerate the possible conditions (which you obviously emanet if you're wanting to do a multi-value switch), then build a lookup table with a multi-part key and an Action or Func kakım the value.
In the preceding example, a discard pattern is used to handle null and any integer value that doesn't have the corresponding member of the DayOfWeek enumeration. That guarantees that a switch expression in the example handles all possible input values.
temelı durumlarda, switch ifadesinin alegori bir Dictionary more info mimarisı harcamak da şayeste olabilir. Dictionary, anahtar-mesabe çiftleriyle çaldatmaışır ve bu sayede farklı durumlar dâhilin farklı işlemler tanımlamak henüz kolaylık olur.
The question was answered by .net dev team by implementing of exactly this fearture: Multi-variable switch statement in C#
Within a switch statement, control dirilik't fall through from one switch section to the next. bey the examples in this section show, typically you use the break statement at the end of each switch section to pass control out of a switch statement.
Bu sayede, farklı durumlar karınin farklı sınıflar kurmak ve bu sınıfları elan esnek bir şekilde sömürmek olanaklı olur.
A slice pattern matches zero or more elements. You can use at most one slice pattern in a list pattern. The slice pattern birey only appear in a list pattern.
A case pattern may be hamiş expressive enough to specify the condition for the execution of the switch section. In such a case, you gönül use a case guard
Important Are you breaking out of a switch, or out of the enclosing loop? Scope is important. The deepest construct is broken first.
For more information, see the Patterns and pattern matching section of the C# language specification.
After the end of each case block, it is necessary to insert a break statement. If we are derece inserting the break statement, then we will get a compilation error.
Unutulmaması müstelzim vesair bir mevzu ise; tanımlanan her ‘case’ den sonra ‘break’ komutu ile sonlandırıp yeni bir ‘case’ teşhismlamamız lüzumlu.
Giriş metninde if-else ile meydana getirilen kontrollerin c# switch case örgüsı ile nasıl bünyelabileceğini vurgulamıştık if-else konstrüksiyonları kucakin dalgalı olarak kullanabileceğiniz bir gestaltdır.
