Type Parameters
- T
The type of elements in the hast set.
The HashSet<(Of <(T>)>) class provides high performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.
The capacity of a HashSet<(Of <(T>)>) object is the number of elements that the object can hold. A HashSet<(Of <(T>)>) object's capacity automatically increases as elements are added to the object.
System..::.Object
System.Collections.Generic..::.HashSet<(Of <(T>)>)
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
