如何在Gmap.net WPF中创建路由? [英] How to create a route in Gmap.net wpf?

问题描述

希望您能帮助我.对于GMap.net的WPF版本，我在网络上找不到任何有用的信息.

I hope you can help me. I can not find anything helpful in the web for the WPF version of GMap.net.

问题:我看不到我的路线.

Problem: I don't see my route.

List<Location> points = PolylinePoint.Decode(responseData.routes.First().overview_polyline.points);

GMap.NET.WindowsPresentation.GMapRoute route = new GMap.NET.WindowsPresentation.GMapRoute(points.Select(x => new PointLatLng(x.Latitude.Value, x.Longitude.Value)));
route.ZIndex = ROUTESLIST;
route.Shape = new Line() { StrokeThickness = 4, Stroke = System.Windows.Media.Brushes.BlueViolet };
this.routenList.Clear();
this.routenList.Add(route);

主要问题是，我无法使用GMap.NET教程中的叠加层.

The main problem is, that I can not use an overlay like in the GMap.NET tutorials.

有什么建议吗?

推荐答案

    RoutingProvider routingProvider = 
       _map.MapProvider as RoutingProvider ?? GMapProviders.OpenStreetMap;

    MapRoute route = routingProvider.GetRoute(
        new PointLatLng(35.834914, -76.009508), //start
        new PointLatLng(35.854914, -76.009508), //end
        false, //avoid highways 
        false, //walking mode
        (int)_map.Zoom);

    GMapRoute gmRoute = new GMapRoute(route.Points);

    _map.Markers.Add(gmRoute);
