Determines whether the calling SqlGeometry instance crosses the specified SqlGeometry instance.

命名空間：  Microsoft.SqlServer.Types

'用途
Dim instance As SqlGeometry

returnValue = instance.STCrosses(other)

member STCrosses : 
        other:SqlGeometry -> SqlBoolean

public function STCrosses(
    other : SqlGeometry
) : SqlBoolean

參數

• other
  型別：Microsoft.SqlServer.Types.SqlGeometry
  The SqlGeometry instance to compare against the instance on which STCrosses is invoked.

傳回值

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

備註

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.
