Exceptions

Type	Reason
NotSupportedException	The current instance is read-only or has a fixed size.

Remarks

Note:

This method can be used to minimize the memory overhead of the current instance if no new elements will be added to it.

To completely clear all elements from the current instance, call the ArrayList.Clear method before calling ArrayList.TrimToSize.

Operation

As described above.

If the ArrayList.Count of the current instance is zero, the ArrayList.Capacity of the current instance is set to the default initial capacity of 16.
