List implements IList, and so güç be assigned to the variable. There are also other types that also implement IList.

However using a concrete implementation and List on a class that changes, could cause the calling C# IList Nerelerde Kullanılıyor code to need to be changed birli well.

But if you're interacting with outside code, like when you're returning a list from a method, then C# IList Neden Kullanmalıyız you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

Şimdi beraber C# IList Nasıl Kullanılır bir örnek yapalım. Bir tek yönlü rabıtalı liste oluşturalım ve bu listeye gelişigüzel olarak eleman ekleyelim. Bu eklediğimiz elemanları da ekrana yazdıralım:
