GMap.NET C＃，没有Google Distance Matrix Api的2点之间的距离

Question

我正试图在C＃中的Windows窗体中使用GMaps。我已经创建了确切的路线，但有没有办法计算GMaps.NET中路线的距离和持续时间，除了调用Google Distance Matrix Api之外，还有为此目的实现的功能吗？

Answer 1

我正在寻找的功能名为“距离”。这是获取路线距离的方法：

            inicial = new PointLatLng(googleGeoCoding(txtorigin.Text).Item2,googleGeoCoding(txtorigin.Text).Item3);

            final = new PointLatLng(googleGeoCoding(txtdest.Text).Item2, googleGeoCoding(txtdest.Text).Item3);


            GDirections routedir;
            var routefromtable = GMapProviders.GoogleMap.GetDirections(out routedir, inicial, final, chbxhighways.Checked, chbxtolls.Checked, rbtnwalking.Checked, false, false);

            GMapRoute tablemaproute = new GMapRoute(routedir.Route, "Ruta ubication");

            GMapOverlay tablerouteoverlay = new GMapOverlay("Capa de la ruta");

            tablerouteoverlay.Routes.Add(tablemaproute);

            gMapControl1.Overlays.Add(tablerouteoverlay);
            gMapControl1.Zoom = gMapControl1.Zoom + 1;
            gMapControl1.Zoom = gMapControl1.Zoom - 1;

            double distance = tablemaproute.Distance;
            MessageBox.Show(distance.ToString());
