List is a specific implementation of IList, which is a container that can be addressed the same way kakım a linear array T[] using an integer index.

You dirilik pass a plain C# IList Nedir array to something which accepts an IList parameter, and then you hayat call IList.Add() and will receive a runtime exception:

It doesn't affect the signature of the method, and is grup 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 where his confusion clearly lies.
