Syntax
public class PolygonGeometry : VectorGeometryRemarks
A PolygonGeometry is a geometry that consists of a collection of rings where each ring is represented by a LineGeometry. The ring at index zero is the outline of the polygon.
Note
A ring that is added to a polygon will be closed automatically and its LineGeometry.Closed property will return True.
