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 ArrayList.Clear method before calling ArrayList.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 ArrayList.Count.
