IList is for when you want to create your own, special sub-class that implements List.

The cost to do this is C# IList Nedir minimal, why not save yourself the headache later? It's what the interface principle is all about.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed as well. This is C# IList Nasıl Kullanılır because a class adhering to IList guarantees a certain behavior that is not guaranteed by a concrete type using List.

IList is best for when you need to make 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 .Safi to recognize C# IList Nedir it birli a list.
