Method hiding in C # classes

Question

I am looking at the implementation of a class LinkedListin C # and I cannot understand how the Add Method is hidden.

LinkedListimplements ICollectionwhich method has Add. In class code, a LinkedListmethod is Adddeclared as:

void ICollection<T>.Add(T value);

How can one have an internal method declared in an interface?

The interface is implemented explicitly.

Interface elements implemented using Explicilty can only be accessed through an instance of the implemented interface, for example:

LinkedList list;
((ICollection)list).Add(...)
