SqlGeometry.STGeometryN 方法
Returns the specified SqlGeometry in a SqlGeometry collection.
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 STGeometryN ( _
n As Integer _
) As SqlGeometry
用法
Dim instance As SqlGeometry
Dim n As Integer
Dim returnValue As SqlGeometry
returnValue = instance.STGeometryN(n)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlGeometry STGeometryN(
int n
)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlGeometry^ STGeometryN(
int n
)
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STGeometryN :
n:int -> SqlGeometry
public function STGeometryN(
n : int
) : SqlGeometry
参数
- n
类型:System.Int32
An int expression between 1 and the number of SqlGeometry instances in the SqlGeometry collection that specifies the instance to return.
返回值
类型:Microsoft.SqlServer.Types.SqlGeometry
The SqlGeometry specified by n.
注释
This method returns null if the parameter is larger than the result of STNumGeometries and will throw an ArgumentOutOfRangeException if the expression parameter is less than 1
