將路由與WCF服務

Question

我已經在應用中使用WCF服務。

從1開始繪製從WCF返回的座標時繪製直線。然後畫出錯誤的路徑。當Windows Phone 7正確顯示時，使用折線。

下面顯示的是，我得到錯誤的結果：

我想顯示：

這是我處理繪製代碼：

void wcl_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) 
{ 
    try 
    { 
     if (string.IsNullOrEmpty(e.Result) || e.Error != null) 
     {

      return;

       Width =5, 
       Height = 5

     } 
    }); 
} 

void pus_Tap(object sender, System.Windows.Input.GestureEventArgs e) 
{ 
    e.Handled = true; 
    Pushpin pus = sender as Pushpin; 
    ToolTipService.SetToolTip(pus, new ToolTip() 
    { 
     DataContext = pus, 
     Style = Application.Current.Resources["CustomInfoboxStyle"] as Style 
    }); 
    MessageBox.Show(pus.Content.ToString(), "Thông tin trạm", MessageBoxButton.OK); 
} 

這是pl王牌，我創建數據庫：

我該如何解決這個問題？

Answer 1

我想這是因爲你的旅行模式設置爲走路，谷歌似乎認爲走在那裏是不允許的，所以它採取下一個可能的方式。嘗試改變旅行模式駕駛或左右。
