STInteriorRingN 方法
Returns the specified interior ring of a Polygon SqlGeometry instance.
命名空间： Microsoft.SqlServer.Types
程序集： Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）
语法
声明
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := True)> _
Public Function STInteriorRingN ( _
n As Integer _
) As SqlGeometry
用法
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
参数
- n
类型：System. . :: . .Int32
An int expression between 1 and the number of interior rings in the SqlGeometry instance.
返回值
类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents the interior ring of the Polygon.
注释
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.
