Foreach大JSON

如何在此Json中使用foreach，我嘗試使用多個foreach，但我無法做到，我只想檢索座標數據。Foreach大JSON

目前這是我的代碼來檢索數據和此代碼不起作用，我得到一個錯誤：（Newtonsoft.Json.Linq.JProperty'不包含'座標'的定義）。

String toto = await response.Content.ReadAsStringAsync(); 
dynamic jsonn = JValue.Parse(toto); 
dynamic deserializedValue = JsonConvert.DeserializeObject(toto); 


       foreach (var data in deserializedValue.resourceSets) 
       { 
        foreach (var data1 in data.resources) 
        { 
         foreach (var data2 in data1.point) 
         { 
          foreach (var data3 in data2.coordinates) 
          { 
           var message = new MessageDialog("Coord: " + data3.coordinates); 
           await message.ShowAsync(); 
          } 

         } 
        } 
       } 
      }

我喜歡「動態」的可用性，但這對我來說是一種代碼味道。我很難找到許多用於動態的用途，除了客戶端之外，我發現它非常方便;但通常將我的用途限制在該模式。爲了以這種方式處理對象，我可能會建議更具體的模式來表示節點。在編譯之前，Intellisense會挑選你的問題。 – Hardrada

point是一個對象，而不是一個數組。

"point": {  // <- Notice the '{' 
     "type": "Point", 
     "coordinates": [ 
      46.637279510498047, 
      2.3382623195648193 
     ] 
     },

這裏是你如何閱讀：

foreach (var set in deserializedValue.resourceSets) 
{ 
    foreach (var resource in set.resources) 
    { 
     foreach (var coord in resource.point.coordinates) 
     { 
      var message = new MessageDialog("Coord: " + coord); 
      await message.ShowAsync(); 
     } 
    } 
}

看結構：

{ <---layer #1 
    "authenticationResultCode": "ValidCredentials", 
    "brandLogoUri": "http:\/\/dev.virtualearth.net\/Branding\/logo_powered_by.png", 
    "copyright": "Copyright ...", 
    "resourceSets": [ <-- layer #2 
     { <-- layer #3 
      "estimatedTotal": 1, 
      "resources": [ <-- layer #4 
       { <-- layer #5 
         "__type": "Location:http:\/\/schemas.microsoft.com\/search\/local\/ws\/rest\/v1", 
         "bbox": [ 
          41.298164367675781, 
          -5.2461638450622559, 
          51.099018096923828, 
          9.6006984710693359 
         ], 
         "name": "France", 
         "point": { <--layer #6 
         "type": "Point", 
         "coordinates": [

coordinates是6層下來，你有4層未築巢夜代碼。

謝謝您的回答，現在我應該怎麼座標轉換成字符串？
