The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.

Use whatever you want. It's your method. You're the only one who gets to see the internal implementation details of the method.

In some code this güç be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this set of methods, no other contract implied."

Inside the method, you should use var, instead of IList or List. When your data source changes to come from a method instead, your onlySomeInts method will survive.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed C# IList Kullanımı as well. This is because a class adhering to IList guarantees a certain behavior that is not guaranteed by a concrete type using List. Also having the power to do something like modify the default implementation of List on a class Implementing IList for say the .Add, .Remove or any other IList method gives the developer a lot

The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

However, this makes the method more fragile, bey any change to the returned object type may break the calling code. In practice though, that generally isn't a major sıkıntı.

Şimdi bu arada bir örnek yapalım. Bir tenha yönlü bağlamlı liste oluşturalım ve bu listeye herhangi olarak eleman ekleyelim. Bu eklediğimiz elemanları da ekrana yazdıralım:

So typically, your methods should accept and return C# IList Neden Kullanmalıyız interfaces for collections. This leaves your own implementation and your callers room to decide on the actual implementation birli required.

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are C# IList Kullanımı free to change your implementation. List happens to implement all three of those interfaces. If you expose your property bey a List or even an IList when all you C# IList Nedir want your consumer to have is the ability to C# IList Kullanımı iterate through the collection. Then they could come to depend on the fact that they gönül modify the list.
