SqlGeometry.STExteriorRing Method
Returns the exterior ring of a SqlGeometry instance that is a polygon.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function STExteriorRing As SqlGeometry
'Usage
Dim instance As SqlGeometry
Dim returnValue As SqlGeometry
returnValue = instance.STExteriorRing()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlGeometry STExteriorRing()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:

public function STExteriorRing() : SqlGeometry
Return Value
Type: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the exterior ring of the calling instance.
Remarks
This method returns nulla null reference (Nothing in Visual Basic) if the SqlGeometry instance is not a polygon.
