STUnion 方法

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

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 null Nothing nullptr unit null 引用（在 Visual Basic 中为 Nothing） if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
