傳回值
型別:System.Data.SqlTypes.SqlInt32
A SqlInt32 value that specifies the number of geometries that make up the SqlGeography instance.
備註
This method returns 1 if the geography instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, or 0 if the SqlGeography instance is empty.
