// 添加多边形节点  List<PointLatLng> points = new List<PointLatLng>();  points.Add(new PointLatLng(37.1412768409666, 79.6562057733536));  points.Add(new PointLatLng(37.1403574434934, 79.6564793586731));  points.Add(new PointLatLng(37.1405669815751, 79.6581155061722));  points.Add(new PointLatLng(37.1416146632773, 79.6577936410904));  points.Add(new PointLatLng(37.1412768409666, 79.6562057733536));     //绘制折线用GMapRoute  GMapRoute route = new GMapRoute(points, "");  route.Stroke = new Pen(Color.Red, 1); // 折线颜色，线宽  polyOverlay.Routes.Add(route);    //绘制多边形用GMapPolygon  GMapPolygon polygon = new GMapPolygon(points, "polygons");  polygon.Fill = new SolidBrush(Color.FromArgb(50, Color.Green));// 配置多边形填充颜色  polygon.Stroke = new Pen(Color.Red, 1);  polyOverlay.Polygons.Add(polygon);  gMapControl.Overlays.Add(polyOverlay);
