Тип: Microsoft.SqlServer.Types.SqlGeometry
The SqlGeometry instance to compare to the current SqlGeometry.
Возвращаемое значение
Тип: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents all points in the calling SqlGeometry and the specified SqlGeometry instances that are not present in both instances..
Замечания
This method always returns nullпустая ссылка (Nothing в Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
