member TrimExcess : unit -> unit

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.

The following example creates and populates a HashSet<'T> collection, and then clears the collection and releases the memory referenced by it.
