STTouches 方法
Determines whether the specified SqlGeometry touches the current SqlGeometry.
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 STTouches ( _
other As SqlGeometry _
) As SqlBoolean
用法
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim returnValue As SqlBoolean
returnValue = instance.STTouches(other)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STTouches(
SqlGeometry other
)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlBoolean STTouches(
SqlGeometry^ other
)
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STTouches :
other:SqlGeometry -> SqlBoolean
public function STTouches(
other : SqlGeometry
) : SqlBoolean
参数
- other
类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
The SqlGeometry instance to compare to the current SqlGeometry.
返回值
类型：System.Data.SqlTypes. . :: . .SqlBoolean
Returns true if a SqlGeometry instance spatially touches another SqlGeometry instance. Returns false if it does not.
注释
Two SqlGeometry instances touch if their point sets intersect, but their interiors do not intersect.
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.
