Why can't I retrieve an item from a HashSet without enumeration?

I need to add a lot of objects to a Set.and I should retrieve them very fast. The only way that I know is using hash. But the HashSet class in C# doesn't contain any 'Get' method. The dictionary class isn't useful because Finding an object is very time-consuming in a dictionary.

Answer 1

HashSets are basically used to test if an object is included in the collection. It is un-orderd and un-sorted, doesnt have an index that could be used to retrive an object.

If you need to store and retrieve objects, use other collection types like List, HashTable etc.
