ArcGis Runtime for.net

  请尝试，如下代码：  
 public static Polygon SetSector(MapPoint Location)
        {
             GeodesicSectorParameters para = new GeodesicSectorParameters(0,AngularUnits.Degrees, Location,LinearUnits.Kilometers,5,10,GeometryType.Polygon,90,40,40,90);
             Polygon SectorPolygon = GeometryEngine.SectorGeodesic(para) as Polygon;
             return SectorPolygon;
        }

        public static void DrawPolygonGraphic(Polygon polygonShape, GraphicsOverlay polygonGraphicOverlay)
        {
            var outlineSymbol = new SimpleLineSymbol(SimpleLineSymbolStyle.Dash, Colors.Blue, 3.0);
            var fillSymbol = new SimpleFillSymbol(SimpleFillSymbolStyle.Cross, Colors.Aqua, outlineSymbol);
            Graphic poygonGraphic = new Graphic(polygonShape, fillSymbol);
            polygonGraphicOverlay.Graphics.Add(poygonGraphic);
        }
效果图：
