NameValueCollection.InvalidateCachedArrays Method

Resets the cached arrays of the collection to null.

Namespace:  System.Collections.Specialized
Assembly:  System (in System.dll)

protected void InvalidateCachedArrays()

The arrays returned by AllKeys are cached for better performance and are automatically refreshed when the collection changes. A derived class can invalidate the cached version by calling InvalidateCachedArrays, thereby forcing the arrays to be recreated.

This method is an O(1) operation.
