HashSet<T>.TrimExcess Method

Sets the capacity of a HashSet<T> object to the actual number of elements it contains, rounded up to a nearby, implementation-specific value.

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

public void TrimExcess()

You can use the TrimExcess method to minimize a HashSet<T> object's memory overhead once it is known that no new elements will be added. To completely clear a HashSet<T> object and release all memory referenced by it, call this method after calling the Clear method.

This method is an O(n) operation, where n is Count.
