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)

Syntax

'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function STNumGeometries As SqlInt32
'Usage
Dim instance As SqlGeometry
Dim returnValue As SqlInt32

returnValue = instance.STNumGeometries()

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

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

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STNumGeometries : unit -> SqlInt32

public function STNumGeometries() : SqlInt32

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.

Remarks

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.
