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.
The capacity is always greater than or equal to Count. If Count exceeds the capacity while adding elements, the capacity is set to the first prime number that is greater than double the previous capacity.
