Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does hamiş.

You sevimli pass a plain array to something which accepts an IList parameter, and then you kişi call IList.Add() and will receive a C# IList Nedir runtime exception:
The other general reason for using interfaces is to expose the minimum amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a data object that implements IList.
