Is there a Collection that works like a Dictionary without the values?

Question

I need a collection that works just like a Dictionary/Hashtable in a sense that it will only contain 1 instance of a given object at any time. A generic class would be preferable, but I'll take what I can get. Does this collection live somewhere in the framework?
