json.net with c sharp

Question

string jsondata = @"{""meta"":{""code"":200}}";
dynamic json = JsonConvert.DeserializeObject(jsondata);

我有上面的json数据，我为它创建了类。我还对它进行了反序列化——我如何迭代这个json变量

public class Meta
{
    public int code { get; set; }
}
public class RootObject
{
    public Meta meta { get; set; }
}

Answer 1

要使用您的代码，您应该使用键入的convert

string jsondata = @"{""meta"":{""code"":200}}"; 
Meta json = JsonConvert.DeserializeObject<Meta>(jsondata);

然后你可以访问元对象中的所有成员。

使用普通的.net json运行时，您可以反序列化字符串

string jsondata = @"{""meta"":{""code"":200}}"
Meta meta = JsonHelper.JsonDeserialize<Meta>(jsondata);

你需要有这个代码的C

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Runtime.Serialization.Json;
 using System.IO;
 using System.Text;  
 /// <summary>
 /// JSON Serialization and Deserialization Assistant Class
 /// </summary>
 public class JsonHelper
 {
     /// <summary>
     /// JSON Serialization
     /// </summary>
     public static string JsonSerializer<T> (T t)
     {
         DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
         MemoryStream ms = new MemoryStream();
         ser.WriteObject(ms, t);
         string jsonString = Encoding.UTF8.GetString(ms.ToArray());
         ms.Close();
         return jsonString;
     }  
     /// <summary>
     /// JSON Deserialization
     /// </summary>
     public static T JsonDeserialize<T> (string jsonString)
     {
         DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
         MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
         T obj = (T)ser.ReadObject(ms);
         return obj;
     }
 }
