The Array class implements these interfaces IClonable, IList, ICollection

In Interface IList have a couple of members that is not available from the

For example if I do the following
int[] vector = new int[5];
And then use the intellisense on instance vector I can't see for example
Add, Remove RemoveAt
there are more but these are just example of members that are not available
from the vector instance.

I must have missed something here about implementing interfaces !
I have always thought that all implemented members must be accessible from
the derived class which
is not the case in this example.

They are accessible from the class, but they are implemented explicitly,
which means that you need an IList reference to access them.
This compiles:
((IList)someArray).Add(42);
Of course it throws a NotSupportedException if you try to run the code.
