My question has always been:
So I'm asking how to retrieve both data, I can only retrieve the 'Key' at the moment.
The direct answer to that question is that you use the Item property of the HashTable and pass in the key as an indexer. See here for a simple example. If that's absolutely all you want then stop reading now.

I think the "run on" nature of the thread, though, has come from the fact that we're not 100% sure of your more general requirement. We're not sure a HashTable's really the best data structure for you to be using (in fact, we're fairly sure there'll be a better one available) and we'd like to give you a little bit more than the simple answer above. But because we've got some unanswered questions about the more general requirement we don't really know what that "little bit more" should look like.

You've averred several time to being admonished by JMc (yeah, he does do that, but you can't fault his knowledge and he has a thoroughly annoying habit of being right) so I'm guessing there was another thread that lead you to starting to this one. It might be worth providing a link to it. I wouldn't want to encourage everyone to ghoulishly pick over any rows you may have had but it might provide us with a short cut to understanding what your underlying goal is.
