The object could be in a state where it is not yet associated with, or has been detached from, an array. Asking the object for the number of elements should return... What?


0. No elements would be retrievable.

Returning zero means that the collection has a size of zero, not that there is no collection.


Why sould the "GetSize"-function answer a question other than that "How many elements are in the collection?". There are no elements to be retrieved, so the answer is null.

If your collection happens to have a state of being "invalid", there sould be another function to test that.
Note that I would have the actual access-routines return a proper error code.
