Else use List. You sevimli't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List derece an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

Then the person calling the method is free to call it with any veri type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.

Elemanların Sıralı Yapkaloriı Esirgeme: IList, elemanların eklenme sırasını korur. Bu özellik, data yapkaloriın sıralı olmasını ve yetişekın beklentilerine münasip çtuzakışmasını sağlar.

Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that C# IList Neden Kullanmalıyız uses your class.

In some code this gönül be quite important and using concrete classes communicates your intent, C# IList Nasıl Kullanılır your need for that specific class. An interface on the other hand says "I just need to C# IList Nerelerde Kullanılıyor call this takım of methods, no other contract implied."

Returning a read-only interface such bey IEnumerable is often the way to go for data-retrieval methods. Your consumer can project it into a richer type birli-needed.

And, if you used a generic implementation, you would only be able to use a method that works for any object only with objects of C# IList Nedir a specific type.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
