Zusätzliche Informationen

The CreatePolygon method inserts each polyline as a separate part; however, each polyline contains only two points. The resulting polygon has four parts, each of which degenerates to a line. When SimplifyAsFeature is called, the degenerate parts are removed, leaving an empty polygon. Instead of creating two-point polylines, create line segments and either call PolygonBuilderEx.AddSegment for each segment, or create the polygon by using PolygonBuilderEx.CreatePolygon. Here is an example. // Define input polyline edges (clockwise) Segment lnN = LineBuilderEx.CreateLineSegment(MapPointBuilderEx.CreateMapPoint(0, 10), MapPointBuilderEx.CreateMapPoint(10, 10)); Segment lnE = LineBuilderEx.CreateLineSegment(MapPointBuilderEx.CreateMapPoint(10, 10), MapPointBuilderEx.CreateMapPoint(10, 0)); Segment lnS = LineBuilderEx.CreateLineSegment(MapPointBuilderEx.CreateMapPoint(10, 0), MapPointBuilderEx.CreateMapPoint(0, 0)); Segment lnW = LineBuilderEx.CreateLineSegment(MapPointBuilderEx.CreateMapPoint(0, 0), MapPointBuilderEx.CreateMapPoint(0, 10)); Polygon plyNew = PolygonBuilderEx.CreatePolygon(new Segment[] { lnN, lnE, lnS, lnW }); double length = plyNew.Length; // length = 40 Polygon simplifiedPolygon = GeometryEngine.Instance.SimplifyAsFeature(plyNew) as Polygon; length = simplifiedPolygon.Length; // length = 40 bool isSimple = GeometryEngine.Instance.IsSimpleAsFeature(simplifiedPolygon); // isSimple = true
