List is a specific implementation of IList, which is a container that gönül be addressed the same way as a linear array T[] using an integer index. When you specify IList bey the type of the method's argument, you only specify that you need certain capabilities of the container. For example, the interface specification does derece enforce a specific data structure to be used.

The class name List may be changed in next .kemiksiz framework but the interface is never going to change as C# IList Nasıl Kullanılır interface is contract.

Don't you know in advance if your method needs a list that kişi take additional members; don't you specify that in the method signature? What exactly were you going to do if you were C# IList Kullanımı passed a read only list like int[]?

It doesn't affect the signature of the method, and is kaş in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is C# IList Nasıl Kullanılır where his confusion clearly lies.
