Remarks

The QueryTurn method returns the turn element that traverses from the fromEdge through the atJunction to the QueryEdge edge element at the specified index.  The QueryTurn method does not always return a turn element -- to determine if a turn element will be returned, call the HasTurn property using the same index value.

The index values range from 0 to (Count - 1).

The QueryTurn method requires an instantiated NetworkTurn object to be passed in as a parameter.  You can create an empty NetworkTurn object by using the INetworkQuery::CreateNetworkElement method.
