如何遍歷列表字典並打印其內容？

Question

我交流＃新手，我想通了，讓使用HttpClient的，並用下面的代碼我得到了來自服務器的JSON如下所示的API的響應：

class Program 
{ 
    public class Parameter 
    { 
     public Usuario Usuario { get; set; } 
     public Establecimiento Establecimiento { get; set; } 
    } 
    public class Usuario 
    { 
     public string email { get; set; } 
     public string password { get; set; } 
    } 

    public class Establecimiento 
    { 
     public int id { get; set; } 
    } 

    public class deliveryData 
    { 
     public string id { get; set; } 
     public string establecimiento_id { get; set; } 
     public string numero_orden { get; set; } 
     public string ciudad_id { get; set; } 
     public string fecha { get; set; } 
    } 

    static void Main() 
    { 
     try 
     { 
      RunAsync().Wait(); 
      Console.ReadLine(); 
     } 
     catch (AggregateException e) 
     { 
      Console.WriteLine("Exception details: " + e.ToString()); 
      Console.ReadLine(); 
     } 
    } 

    static async Task RunAsync() 
    { 
     using (var client = new HttpClient()) 
     { 
      client.BaseAddress = new Uri("http://it-215...web.development.co/"); 
      client.DefaultRequestHeaders.Accept.Clear(); 
      client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

      try 
      { 
       // HTTP POST 
       var json = new Parameter 
       { 
        Establecimiento = new Establecimiento 
        { 
         id = 147 
        }, 
        Usuario = new Usuario 
        { 
         email = "user@email.com", 
         password = "something" 
        } 
       }; 

       HttpResponseMessage response = await client.PostAsJsonAsync("api/service", json); 
       response.EnsureSuccessStatusCode(); // Throw if not a success code. 
       string responseBodyAsText; 
       responseBodyAsText = await response.Content.ReadAsStringAsync(); 
       Console.WriteLine(responseBodyAsText); 

       //List<Dictionary<string, deliveryData>> decodedDeliveries = JsonConvert.DeserializeObject<List<Dictionary<string, deliveryData>>>(responseBodyAsText); 

       //foreach (var delivery in decodedDeliveries) 
       //{ 
       // Console.WriteLine(delivery.ToString()); 
       //} 

      } 
      catch (HttpRequestException e) 
      { 
       Console.WriteLine("Exception details: " + e.ToString()); 
      } 
     } 
    } 
} 

JSON響應，直到在這裏：

[ { 
    "PedidosOnline": { 
     "id": "7491031", 
     "establecimiento_id": "147", 
     "numero_orden": "1769629-20160509211442", 
     "fecha": "2016-05-09 21:14:42" 
    } 
    }, { 
    "PedidosOnline": { 
     "id": "7491328", 
     "establecimiento_id": "147", 
     "numero_orden": "1559397-20160509212644", 
     "fecha": "2016-05-09 21:26:44" 
    } 
} ] 

現在，當我發表意見

Console.WriteLine（responseBodyAsText）;

，並取消對解碼線和在foreach，這是我得到：

System.Collections.Generic.Dictionary`2[System.String,ProjectName.Program+deliveryData] 
System.Collections.Generic.Dictionary`2[System.String,ProjectName.Program+deliveryData] 

我想要的是得到的JSON觀看的字段的清洗打印，因爲我的下一步是在Access數據庫中保存字典的每個字段（我不知道該怎麼做，但我會弄清楚）。所以我需要一點幫助，任何建議都會非常讚賞。

非常感謝提前。

而不是打印Dictionary對象本身，循環遍歷每個Dictionary並打印每個鍵值對。

List<Dictionary<string, deliveryData>> decodedDeliveries = JsonConvert.DeserializeObject<List<Dictionary<string, deliveryData>>>(responseBodyAsText); 

foreach (var delivery in decodedDeliveries) 
{ 
    foreach(var pair in delivery) { 
    Console.WriteLine(pair.Key + " : " + pair.Value); 
    } 
}
