PolylineBuilder Constructor(IEnumerable<MapPoint>)

Initializes a new instance of the PolylineBuilder class. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public PolylineBuilder( 
   IEnumerable<MapPoint> points
)

Public Function New( _
   ByVal points As IEnumerable(Of MapPoint) _
)

Parameters

points: Points for the first part.

Exceptions

Exception	Description
System.InvalidOperationException	Incompatible spatial references
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.
System.ArgumentNullException	points is null.

Example

List<MapPoint> firstPoints = new List<MapPoint>();
firstPoints.Add(MapPointBuilder.CreateMapPoint(1.0, 1.0));
firstPoints.Add(MapPointBuilder.CreateMapPoint(1.0, 2.0));
firstPoints.Add(MapPointBuilder.CreateMapPoint(2.0, 2.0));
firstPoints.Add(MapPointBuilder.CreateMapPoint(2.0, 1.0));

List<MapPoint> nextPoints = new List<MapPoint>();
nextPoints.Add(MapPointBuilder.CreateMapPoint(11.0, 1.0));
nextPoints.Add(MapPointBuilder.CreateMapPoint(11.0, 2.0));
nextPoints.Add(MapPointBuilder.CreateMapPoint(12.0, 2.0));
nextPoints.Add(MapPointBuilder.CreateMapPoint(12.0, 1.0));

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (PolylineBuilder pBuilder = new PolylineBuilder(firstPoints))
  {
    pBuilder.AddPart(nextPoints);

    Polyline polyline = pBuilder.ToGeometry();
    // polyline p has 2 parts

    pBuilder.RemovePart(0);
    polyline = pBuilder.ToGeometry();
    // polyline p has 1 part
  }
});
