The ArrayList is read-only.

-or-

The ArrayList has a fixed size.

Count is set to zero, and references to other objects from elements of the collection are also released.

Capacity remains unchanged. To reset the capacity of the ArrayList, call TrimToSize or set the Capacity property directly. 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.
