| NotSupportedException | The ArrayList is read-only. -or- The ArrayList has a fixed size. |
Remarks
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.
