CreatePolygon(Envelope,SpatialReference) Method

Convenience method to create a new instance of the Polygon class.

Syntax

C#
Visual Basic (Declaration)

public static Polygon CreatePolygon( 
   Envelope envelope,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreatePolygon( _
   ByVal envelope As Envelope, _
   Optional ByVal spatialReference As SpatialReference _
) As Polygon

Parameters

envelope: The envelope to create the polygon. Note that if the envelope has z-values, they will be interpolated for the upper right and lower left vertices.
spatialReference: (Optional) The SpatialReference. The default value is null. If spatialReference is null, then the spatial reference will be inherited from envelope.

Return Value

A Polygon.

Exceptions

Exception	Description
System.ArgumentNullException	envelope is null.

Example

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

MapPoint minPt = MapPointBuilder.CreateMapPoint(1.0, 1.0);
MapPoint maxPt = MapPointBuilder.CreateMapPoint(2.0, 2.0);

// Create an envelope
Envelope env = EnvelopeBuilder.CreateEnvelope(minPt, maxPt);

// Builder convenience methods don't need to run on the MCT.
Polygon polygonFromEnv = PolygonBuilder.CreatePolygon(env);

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (PolygonBuilder polygonBuilder = new PolygonBuilder(env))
  {
    polygonBuilder.SpatialReference = SpatialReferences.WGS84;
    polygonFromEnv = polygonBuilder.ToGeometry();
  }
});
