SQL Server return type: int

CLR return type: SqlInt32

Remarks

This method returns 1 if the geometry instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, and 0 if the geometry instance is empty.

Note

If a GeometryCollection has nested empty elements, STNumGeometries() will not return 0. Though the elements in the GeometryCollection instance are empty, the instance itself is not an empty set.
