ReverseOrientation Method

Changes the direction of the MultipartBuilder parts without changing the spatial position of the parts. The From Point and To Point of each Segment in each part of the MultipartBuilder are interchanged. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void ReverseOrientation()

Public Sub ReverseOrientation()

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

Remarks

Caution should be taken in using ReverseOrientation on Polygons. Since ReverseOrientation changes the direction of each part within the Polygon, all Exterior Rings become Interior Rings and vice versa.

GeometryEngine Reverse Orientation

Example

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (PolylineBuilder polylineBuilder = new PolylineBuilder(polyline))
  {
    polylineBuilder.ReverseOrientation();
    Polyline reversedPolyline = polylineBuilder.ToGeometry();
  }
});

Target Platforms: Windows 10, Windows 8.1
