If a SqlGeography instance is user-created, the method returns the point specified by expression by ordering the points in the order in which they were originally input.
If a SqlGeography instance is constructed by the system, returns the point specified by expression by ordering all the points in the same order they would be output: first by geography instance, then by ring within the instance (if appropriate), and then by point within the ring. This order is deterministic.
If this method is called with a value less than 1, it throws an ArgumentOutOfRangeException.
If this method is called with a value greater than the number of points in the instance, it returns Nothing.
