MultipointBuilder Constructor(IEnumerable<MapPoint>)

Initializes a new instance of the MultipointBuilder class. This method must be called on the MCT. Use QueuedTask.Run. All the points must be in the same spatial reference.

Syntax

C#
Visual Basic (Declaration)

public MultipointBuilder( 
   IEnumerable<MapPoint> points
)

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

Parameters

points: An enumeration of points which will intialize the builder.

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

// Use a builder convenience method or use a builder constructor.

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

// Builder convenience methods don't need to run on the MCT.
Multipoint multiPoint = MultipointBuilder.CreateMultipoint(list);
int ptCount = multiPoint.PointCount;

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (MultipointBuilder mpb = new MultipointBuilder(list))
  {
    // do something with the builder

    Multipoint mPt = mpb.ToGeometry();

    ptCount = mpb.PointCount;
  }
});

// or use the builderEx constructors = don't need to run on the MCT.
MultipointBuilderEx builderEx = new MultipointBuilderEx(list);
multiPoint = builderEx.ToGeometry() as Multipoint;
ptCount = builderEx.PointCount;
