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 uses your class.

Örneğin, hordaki kodda bir IAnimal tipinde bir parametre teşhismladım ve bu değemekkene Dog ve Cat nesneleri atadım.

+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... Emanet I borrow the phrase "Architecture Astronauts"? I güç see it will come in handy.

IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to C# IList Nedir work with, you are 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 want your consumer to have is the ability to iterate through the collection.
