Copies the endpoints of this line to and '. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void QueryCoords( 
   out MapPoint startPt,
   out MapPoint endPt
)

Public Sub QueryCoords( _
   ByRef startPt As MapPoint, _
   ByRef endPt As MapPoint _
)

Parameters

startPt: The start point.
endPt: The end point.

Example

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  // use the builder constructor
  using (LineBuilder lb = new LineBuilder(lineSegment))
  {
    // find the existing coordinates
    lb.QueryCoords(out startPt, out endPt);

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

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

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

    LineSegment anotherLineSegment = lb.ToSegment();
  }
});
