CLR dönüş türü: SqlGeometry
Remarks
This yöntem returns null if the parameter is larger than the result of STNumGeometries() and will throw an ArgumentOutOfRangeException if the ifade parameter is less than 1.
Örnekler
The following example creates a MultiPointgeometry collection and uses STGeometryN() to find the second geometry instance of the collection.
DECLARE @g geometry;
SET @g = geometry::STGeomFromText('MULTIPOINT(0 0, 13.5 2, 7 19)', 0);
SELECT @g.STGeometryN(2).ToString();
