Casting question

Why is this possible:

DirectCast(obj, IList(Of T)).GetEnumerator

IList does not have the GetEnumerator method according to the documentation
.. Is seems that I get a ICollection interface after the cast. But why?

Cheers,
Robert
 
Hello Robert,

IList(Of T) inherits IEnumerable, so it has GetEnumerator:
IList Generic Interface
http://msdn2.microsoft.com/en-us/library/5y536ey6(VS.80).aspx

Okay, that's easy to understand.
However, can you tell me, when are such members are listet under 'members'
and when not? I just have looked under
http://msdn2.microsoft.com/en-us/library/s16t9z9d(VS.80).aspx where it is
not listed. I have assumed that each member is listed in this section.

Cheers,
Robert

Hi Robert,

Sorry for the delay, I've been on vacation visiting the Maginot Line.

Along the MSDN, the documentation for interfaces doesn't include inherited members, so you need to see also the list of members for the base interfaces.

Regards.
