GeoCoordinateWatcher() 在真正的 Windows 手机设备中? [英] GeoCoordinateWatcher() in real windows phone device?

问题描述

为了获取纬度和经度，我编写了以下代码行.

For getting Latitude and Longitude i wrote the following line of code.

watcher = new GeoCoordinateWatcher();
 var myPosition = myWatcher.Position;

     if (!myPosition.Location.IsUnknown)
          {
                latitude = myPosition.Location.Latitude;
                longitude = myPosition.Location.Longitude;
            }

但是我得到的所有值都是 NAN .请告诉我如何在真实设备中获取当前的纬度和经度?

But i am getting all values as NAN .Please tell me how to get current latitude and longitude in real device?

推荐答案

您是否启动了观察程序?您也可以在模拟器上模拟 GPS.有一个工具可以做到这一点.

Have you started the watcher? Also you can simulate the GPS on emulator. There's a tool for that.

        GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();
        watcher.Start();

        GeoCoordinate coord = watcher.Position.Location;

        if (coord.IsUnknown != true)
        {
            Console.WriteLine("Lat: {0}, Long: {1}",
                coord.Latitude,
                coord.Longitude);
        }
        else
        {
            Console.WriteLine("Unknown latitude and longitude.");
        }
