SqlGeometry.STCrosses Method

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

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

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


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

Return Value

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

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.
