windowsphone中获取手机位置信息

首先在界面中加入一个textblock控件以显示信息

             this.NavigationCacheMode = NavigationCacheMode.Required;
         }

         /// <summary>

         /// <param name="e">描述如何访问此页的事件数据。
         /// 此参数通常用于配置页。</param>
         protected override async void OnNavigatedTo(NavigationEventArgs e)
         {
             //获取手机所在位置
             var geolocator = new Geolocator();

             var geoPosition = await geolocator.GetGeopositionAsync();
             //当前手机所在经纬度位置
             var position = geoPosition.Coordinate.Point.Position;

             txtLocation.Text = string.Format("经度：{0}；纬度：{1}", position.Longitude, position.Latitude);
         }
     }
 }
