windows-phone-7 - 图钉未位于必应地图中

Question

当我手动提供值（纬度和经度）时，图钉工具找不到位置。

这是我的代码：

double dbllat = 13.060407;

double dbllong = 80.249562;

Pushpin mypin = new Pushpin();

watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);

            watcher.MovementThreshold = 40;

            watcher.Start();

            watcher.Position.Location.Latitude = dbllat;

            watcher.Position.Location.Longitude = dbllong;

            mypin .Location.Latitude = dbllat;

            mypin .Location.Longitude = dbllong;

            //CredentialsProvider cp=

            map1.Center = new GeoCoordinate(mypin.Location.Latitude, mypin.Location.Longitude);
            map1.SetView(mypin .Location, 5.0);
            push.Tag = "Location";
            push.Content = "i'm here";
            map1.Children.Add(mypin);
            watcher.Stop();

我可能做错了什么？

Answer 1

如果那是你的错误：

无法路由一个或多个航路点，因为它们离任何道路都太远。

尝试

GeoCoordinate Loc = new GeoCoordinate(dbllat, dbllong);
mypin.Location = Loc;

代替

mypin .Location.Latitude = dbllat;
mypin .Location.Longitude = dbllong;
