SqlGeometry.STNumGeometries-Methode
Returns the number of SqlGeometry that comprise a SqlGeometry instance.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function STNumGeometries As SqlInt32
'Usage
Dim instance As SqlGeometry
Dim returnValue As SqlInt32
returnValue = instance.STNumGeometries()

public function STNumGeometries() : SqlInt32
Rückgabewert
Typ: 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.
Hinweise
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.
