"Are there any simple groups that appear birli zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
But far more importantly, if you are accepting an IList bey a parameter you'd better be careful, because IList and List do not behave the same way. Despite the similarity in name, and despite sharing an interface
Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.
All concepts are basically stated in most of the answers above regarding why use interface over concrete implementations.
ToList first? How about returning it? I don't understand what you mean by "method will survive" when using vars? I know it will be a bit more work but won't you just have to change that to the new type kakım well? So maybe IList to IList?

+1 for all of us who hate it when a small app is loaded with interfaces and clicking on "find definition" takes us somewhere OTHER than the source of the mesele... Güç I borrow the phrase "Architecture Astronauts"? I sevimli see it will come in handy.
Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...
but my problem is that i am derece understanding what is its use and when to use it . So i hope that anyone gönül help me . Thanks .
It really comes down to the kind of functionality you need. I'd suggest using the List class in most cases. IList is best for when you need to make C# IList Nasıl Kullanılır a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, but still want .Kupkuru to recognize it kakım a list.
If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But C# IList Nasıl Kullanılır if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who C# IList Nedir compiles against your code afterward.
Şimdi bu arada bir C# IList Kullanımı örnek yapalım. Bir nazar boncuğu yönlü bağlamlı liste oluşturalım ve bu listeye herhangi olarak eleman ekleyelim. Bu eklediğimiz elemanları da ekrana C# IList Nasıl Kullanılır yazdıralım:
This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't change.
Ancak list tasarrufında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye tanımlayabiliriz fakat kullanılacak veriler makine plakası,telefon numarası kabilinden skorsı yeni veriler kullanıcak ise behemehâl list olarak saklanmalıdır.Şimdi C#’ta list yararlanmaı karınin örneğimize bakalım.
