SqlGeometry::STNumGeometries Method ()

 

Returns the number of SqlGeometry that comprise a SqlGeometry instance.

Namespace:   Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

public:
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
SqlInt32 STNumGeometries()

Return Value

Type: System.Data.SqlTypes::SqlInt32

Returns 1 if the SqlGeometry instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, and 0 if the SqlGeometry instance is empty.

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