Namespace:  System.Collections.Generic
Assembly:  System.Core (in System.Core.dll)

Public Function Add ( _
	item As T _
) As Boolean


Type: T
The element to add to the set.

Return Value

Type: System.Boolean
true if the element is added to the HashSet(Of T) object; false if the element is already present.


ISet(Of T).Add(T)

If Count already equals the capacity of the HashSet(Of T) object, the capacity is automatically adjusted to accommodate the new item.

If Count is less than the capacity of the internal array, this method is an O(1) operation. If the HashSet(Of T) object must be resized, this method becomes an O(n) operation, where n is Count.
