STCrosses 方法

Determines whether the calling SqlGeometry instance crosses the specified 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 STCrosses ( _
    other As SqlGeometry _
) As SqlBoolean
用法
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim returnValue As SqlBoolean

returnValue = instance.STCrosses(other)

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

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

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

public function STCrosses(
    other : SqlGeometry
) : SqlBoolean

参数

返回值

类型：System.Data.SqlTypes. . :: . .SqlBoolean
Returns true if a SqlGeometry instance crosses another geometry instance. Returns false if it does not.

注释

Two SqlGeometry instances cross if both of the following conditions are true:

  • The intersection of the two SqlGeometry instances results in a SqlGeometry whose dimensions are less than the maximum dimension of the source SqlGeometry instances.

  • The intersection set is interior to both source SqlGeometry instances.

This method always returns null if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
