Hello
The doc says that the List property of CollectionBase returns an IList
object. If that is so, then why I'm able to do
List.CopyTo(System.Array, int index) which is again of type
ICollection.CopyTo ?? Since both the IList and ICollection interfaces
do not have a CopyTo member defined..??


thanks

ICollection interface has *CopyTo* method declaration.
So, if you look at "about" *IList* interface then you'll find
that it inherits *ICollection* (that has *CopyTo*).
