Returns an object that represents the union of a SqlGeometry instance with another 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 := False)> _
Public Function STUnion ( _
other As SqlGeometry _
) As SqlGeometry
用法
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim returnValue As SqlGeometry
returnValue = instance.STUnion(other)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeometry STUnion(
SqlGeometry other
)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeometry^ STUnion(
SqlGeometry^ other
)
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STUnion :
other:SqlGeometry -> SqlGeometry
public function STUnion(
other : SqlGeometry
) : SqlGeometry
参数
- other
类型：Microsoft.SqlServer.Types.SqlGeometry
The SqlGeometry instance to combine with the current SqlGeometry.
返回值
类型：Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the union of the calling SqlGeometry and the specified SqlGeometry.
注释
This method always returns nullnull 引用（在 Visual Basic 中为 Nothing） if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
