SqlGeometry.STInteriorRingN Method
Returns the specified interior ring of a Polygon SqlGeometry instance.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function STInteriorRingN ( _
n As Integer _
) As SqlGeometry
'Usage
Dim instance As SqlGeometry
Dim n As Integer
Dim returnValue As SqlGeometry
returnValue = instance.STInteriorRingN(n)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlGeometry STInteriorRingN(
int n
)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlGeometry^ STInteriorRingN(
int n
)
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STInteriorRingN :
n:int -> SqlGeometry
public function STInteriorRingN(
n : int
) : SqlGeometry
Parameters
- n
Type: System.Int32
An int expression between 1 and the number of interior rings in the SqlGeometry instance.
Return Value
Type: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the interior ring of the Polygon.
Remarks
This method returns null if the SqlGeometry instance is not a polygon. This method will also throw an ArgumentOutOfRangeException if the expression is larger than the number of rings. The number of rings can be returned using STNumInteriorRing.
