SymmetricDifference Method (GeometryEngine)

In This Topic

Performs the symmetric difference operation on the two geometries. The symmetric difference is the union of the geometries minus the intersection.

Syntax

C#
Visual Basic (Declaration)

public Geometry SymmetricDifference( 
   Geometry geometry1,
   Geometry geometry2
)

Public Function SymmetricDifference( _
   ByVal geometry1 As Geometry, _
   ByVal geometry2 As Geometry _
) As Geometry

Parameters

geometry1: The first geometry.
geometry2: The second geometry.

Return Value

Returns the result of the symmetric difference.

Exceptions

Exception	Description
System.ArgumentNullException	Either geometry1 or geometry2 or both are null.
System.NotImplementedException	The method is not implemented for GeometryBag.
System.InvalidOperationException	Incompatible spatial references between the input geometries.
ArcGIS.Core.Geometry.Exceptions.InvalidParameterException	Input geometries do not have the same dimension.
ArcGIS.Core.Geometry.Exceptions.GeometryObjectException	The operation cannot be performed on a non-simple geometry.
System.NotImplementedException	Spatial reference of geometry1or geometry2is an image coordinate system.
ArcGIS.Core.Geometry.Exceptions.InvalidParameterException	Input geometries do not have same dimensions.

Remarks

If the input geometries are not known-simple, then the operation will be performed on simplified copies of the geometries. There is no need for you to call any simplify method.
