Sets the capacity to the actual number of elements in the ArrayList.
abstract TrimToSize : unit -> unit
override TrimToSize : unit -> unit
This method can be used to minimize a collection's memory overhead if no new elements will be added to the collection.
To reset a ArrayList to its initial state, call the Clear method before calling TrimToSize. Trimming an empty ArrayList sets the capacity of the ArrayList to the default capacity.
This method is an O(n) operation, where n is Count.
The following code example shows how to trim the unused portions of the ArrayList and how to clear the values of the ArrayList.
