key is a null reference (Nothing in Visual Basic).

If the HybridDictionary does not contain an element with the specified key, the HybridDictionary remains unchanged. No exception is thrown.

If the collection is already stored in a Hashtable and the number of elements falls below the optimal size for a ListDictionary, the collection remains in the Hashtable to avoid the overhead of copying elements from the Hashtable back to a ListDictionary.

This method is an O(1) operation.
