It depends on what exactly from HashSet you're relying on. But yes,
classes such as Hashtable and Dictionary serve the same basic need as
HashSet does. There's even a SortedDictionar y, if you need for your
hashed elements to be ordered.

There is in .NET 3.5, and it's called... Well, I won't spoil it.

Before that, any of the alternatives mentioned by Peter would do. I've
usually used Dictionaries with a dummy value, or Dictionaries where the keys
were the values, depending on what was more convenient. This is not as
efficient as a specialized collection, but it suffices in most cases.
