STSymDifference 方法

Returns an object that represents all points that are either in one SqlGeometry instance or another SqlGeometry instance, but not those points that lie in both instances.

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 STSymDifference ( _
    other As SqlGeometry _
) As SqlGeometry
用法
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim returnValue As SqlGeometry

returnValue = instance.STSymDifference(other)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeometry STSymDifference(
    SqlGeometry other
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeometry^ STSymDifference(
    SqlGeometry^ other
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STSymDifference : 
        other:SqlGeometry -> SqlGeometry 

public function STSymDifference(
    other : SqlGeometry
) : SqlGeometry

参数

• other
  类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
  The SqlGeometry instance to compare to the current SqlGeometry.

返回值

类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents all points in the calling SqlGeometry and the specified SqlGeometry instances that are not present in both instances..

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.
