為Windows Phone反序列化動態json

Question

以下是我的Json數據的c＃類：

[DataContract]
 public class RootObject
 {
           [DataMember(Name="success")]
           public bool success { get; set; }
          [DataMember(Name="deal")]
          public Deal deal { get; set; }
}
[DataContract]
public class Deal
{
    [DataMember(Name = "child_1")]
    public List<Child12> child_1 { get; set; }
    [DataMember(Name = "child_2")]    
    public List<Child12> child_2 { get; set; }
    [DataMember(Name = "child_3")]
    public List<Child12> child_3 { get; set; }
    [DataMember(Name = "child_4")]
    public List<Child12> child_4 { get; set; }
    [DataMember(Name = "child_5")]
    public List<Child12> child_5 { get; set; }
    [DataMember(Name = "child_6")]    
    public List<Child12> child_6 { get; set; }
}

[DataContract]
public class Child12
{
    [DataMember(Name = "scan_count")]
    public string scan_count { get; set; }
    [DataMember(Name = "id")]
    public string id { get; set; }
    [DataMember(Name = "merchant_id")]
    public string merchant_id { get; set; }
    [DataMember(Name = "company_id")]
    public string company_id { get; set; }
    [DataMember(Name = "points_to_earn")]
    public string points_to_earn { get; set; }
    [DataMember(Name = "equivalent_points")]
    public string equivalent_points { get; set; }
    [DataMember(Name = "description")]
    public string description { get; set; }
    [DataMember(Name = "deal_city")]
    public string deal_city { get; set; }
    [DataMember(Name = "price")]
    public string price { get; set; }
    [DataMember(Name = "guidelines")]
    public string guidelines { get; set; }
    [DataMember(Name = "business_name")]
    public string business_name { get; set; }
    [DataMember(Name = "b_type")]
    public string b_type { get; set; }
    [DataMember(Name = "b_image")]
    public string b_image { get; set; }

}

出現問題的是Deal類，每次解析數據時，它都有不同的成員數（即child_1，child_2，.... child_x）。 所以我的問題是如何使動態類Deal，以便可以相應地反序列化json。 我正在使用json.net在Visual Studio 2010中為Windows Phone應用程序開發反序列化json。是否可以完成創建動態類的操作，或者是否有其他方法可以反序列化json。

在此先感謝您的幫助。

Answer 1

在Json.Net中，您可以將“ deal”屬性定義為Dictionary<string,List<Child12>>以實現此目標。

此代碼適用於您的示例。

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DeserializeObject();
            Console.ReadKey();
        }

        private static async void DeserializeObject()
        {
            using (var reader = new StreamReader("TextFile1.txt"))
            {
                var jsonSerializerSettings = new JsonSerializerSettings {TypeNameHandling = TypeNameHandling.Auto};
                var value = await reader.ReadToEndAsync();
                var result = JsonConvert.DeserializeObject<RootObject>(value, jsonSerializerSettings);
            }
        }
    }

    public class RootObject
    {
        public bool success { get; set; }
        public Dictionary<string, List<Child12>> deal { get; set; }
    }

    public class Child12
    {
        public string scan_count { get; set; }
        public string id { get; set; }
        public string merchant_id { get; set; }
        public string company_id { get; set; }
        public string points_to_earn { get; set; }
        public string equivalent_points { get; set; }
        public string description { get; set; }
        public string deal_city { get; set; }
        public string price { get; set; }
        public string guidelines { get; set; }
        public string business_name { get; set; }
        public string b_type { get; set; }
        public string b_image { get; set; }

    }
}

Answer 2

JSON中是否有最大數量的子代，或者可以是任意數量？ 如果JSON每次每次僅包含子代的不同子集，則可以使用包含所有這些出現的超集的目標類，並且目標對象將只包含未誘導子代的null。 據我所知，這就是反序列化的工作方式。

當然，您需要向目標類中的所有這些子級屬性添加適當的屬性，以指示在反序列化數據時並非所有成員都是必需的。

我已經找到了使用動態json的解決方案： 使用JSon.NET對動態數據反序列化JSON

使用了simplejson，之前使用過json.net。
