I need to create a class that represents a integer set using a HashSet<int>. Basically I am lost and I am not sure what to do. I was told to use this class TheHashSet<int> : SetsClass.ISomeInterface Code (markup): Where the interface has functions I need to use in other classes to add to or check what is in the hashset, yes a new method is needed even though there are exisitng methods. Can anyone explain how this works or show me some examples, I have searched before asking. Thanks!
