'用途
Dim instance As SqlGeometry

        n:int -> SqlGeometry

public function STInteriorRingN(
    n : int
) : SqlGeometry

參數

• n
  型別：System.Int32
  An int expression between 1 and the number of interior rings in the SqlGeometry instance.

傳回值

型別：Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the interior ring of the Polygon.

備註

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.
