)

public void SetCoords( 
   MapPoint startPoint,
   MapPoint endPoint
)

startPoint: The start point.
endPoint: The end point.

Exceptions

Exception	Description
System.ArgumentNullException	startPoint or endPoint is null.

Remarks

Line Segment

Example

Alter LineSegment Coordinates

{
  MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0);
  MapPoint endPt = MapPointBuilderEx.CreateMapPoint(2.0, 1.0);
  // builderEx constructors don't need to run on the MCT
  LineBuilderEx lbuilderEx = new LineBuilderEx(lineSegment);
  // find the existing coordinates
  lbuilderEx.QueryCoords(out startPt, out endPt);

  // or use 
  //startPt = lbuilderEx.StartPoint;
  //endPt = lbuilderEx.EndPoint;

  // update the coordinates
  lbuilderEx.SetCoords(GeometryEngine.Instance.Move(startPt, 10, 10) as MapPoint, GeometryEngine.Instance.Move(endPt, -10, -10) as MapPoint);

  // or use 
  //lbuilderEx.StartPoint = GeometryEngine.Instance.Move(startPt, 10, 10) as MapPoint;
  //lbuilderEx.EndPoint = GeometryEngine.Instance.Move(endPt, -10, -10) as MapPoint;

  LineSegment segment2 = lbuilderEx.ToSegment() as LineSegment;
}
