SqlGeometry.STUnion Method

Returns an object that represents the union of a SqlGeometry instance with another SqlGeometry instance.

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

Syntax

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

returnValue = instance.STUnion(other)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeometry STUnion(
    SqlGeometry other
)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeometry^ STUnion(
    SqlGeometry^ other
)
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STUnion : 
        other:SqlGeometry -> SqlGeometry 
public function STUnion(
    other : SqlGeometry
) : SqlGeometry

Parameters

Return Value

Type: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the union of the calling SqlGeometry and the specified SqlGeometry.

Remarks

This method always returns nulla null reference (Nothing in Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
