Resets the cached arrays of the current instance to null.
Note: The array returned by NameValueCollection.AllKeys is cached for better performance and is automatically refreshed when the collection changes. A derived class can invalidate the cached version by calling NameValueCollection.InvalidateCachedArrays, thereby forcing the arrays to be recreated.
