请问这个怎么写一个方法用JISON反序列化把值取出来呢？ 请帮我写一个方法。

请问这个怎么写一个方法用JISON反序列化把值取出来呢？ 请帮我写一个方法。
我不会写反序列化，请帮我用C#把下面的值写一个反序列化。

{
"code": 200,
"msg": "success",
"newslist": [
"TENCENT",
"腾讯控股",
"369.400",
"370.000",
"371.200",
"367.000",
"370.000",
"0.000",
"0.000",
"369.800",
"370.000",
"5967971301",
"16162580",
"41.304",
"0.238",
"475.600",
"251.400",
"2019/03/20",
"16:08"
]
}

public class ResultDto
{
    public int Code { get; set; }
    public string Msg { get; set; }
    public string[] NewsList { get; set; }
}

var str = "{\"code\":200,\"msg\":\"success\",\"newslist\":[\"TENCENT\",\"腾讯控股\",\"369.400\",\"370.000\",\"371.200\",\"367.000\",\"370.000\",\"0.000\",\"0.000\",\"369.800\",\"370.000\",\"5967971301\",\"16162580\",\"41.304\",\"0.238\",\"475.600\",\"251.400\",\"2019/03/20\",\"16:08\"]}";
var dto = Newtonsoft.Json.JsonConvert.DeserializeObject<ResultDto>(str);

首先写个类

public class Info
{
    public string code{get;set;}
    public string msg{get;set;}
    public List<string> newslists{get;set;}
}
然后直接 Info info=Newtonsoft.Json.JsonConvert.DeserializeObject<Info> (data);//data就是你要反序列化的字符串

给你例子，可以仿照来做
首先定义一个类Student

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.Serialization;

namespace JsonSerializerAndDeSerializer
{
 [DataContract]
 public class Student
 {
  [DataMember]
  public int ID { get; set; }

  [DataMember]
  public string Name { get; set; }

  [DataMember]
  public int Age { get; set; }

  [DataMember]
  public string Sex { get; set; }
 }
}

然后

//使用DataContractJsonSerializer方式需要引入的命名空间，在System.Runtime.Serialization.dll.中
using System.Runtime.Serialization.Json;

#region 1.DataContractJsonSerializer方式序列化和反序列化
   Student stu = new Student()
    {
     ID = 1,
     Name = "曹操",
     Sex = "男",
     Age = 1000
    };
   //序列化
   DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(Student));
   MemoryStream msObj = new MemoryStream();
   //将序列化之后的Json格式数据写入流中
   js.WriteObject(msObj, stu);
   msObj.Position = 0;
   //从0这个位置开始读取流中的数据
   StreamReader sr = new StreamReader(msObj, Encoding.UTF8);
   string json = sr.ReadToEnd();
   sr.Close();
   msObj.Close();
   Console.WriteLine(json);


   //反序列化
   string toDes = json;
   //string to = "{\"ID\":\"1\",\"Name\":\"曹操\",\"Sex\":\"男\",\"Age\":\"1230\"}";
   using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(toDes)))
   {
    DataContractJsonSerializer deseralizer = new DataContractJsonSerializer(typeof(Student));
    Student model = (Student)deseralizer.ReadObject(ms);// //反序列化ReadObject
    Console.WriteLine("ID=" + model.ID);
    Console.WriteLine("Name=" + model.Name);
    Console.WriteLine("Age=" + model.Age);
    Console.WriteLine("Sex=" + model.Sex);
   }
   Console.ReadKey(); 
   #endregion

@microsoft 谢谢你，问题已得到解答。

   StudentInfo info = Newtonsoft.Json.JsonConvert.DeserializeObject<StudentInfo>(myjson);//data就是你要反序列化的字符串
            myRobinT[0] = info.Code.ToString().Trim();
            myRobinT[1] = info.Msg;
            myRobinT[2] = info.NewsList[0].ToString().Trim();
            myRobinT[3] = info.NewsList[1].ToString().Trim();
            myRobinT[4] = info.NewsList[2].ToString().Trim();
            myRobinT[5] = info.NewsList[3].ToString().Trim();

            myTempID = "";




    public class StudentInfo
    {
        //public string code { get; set; }
        //public string msg { get; set; }
        //public List<string> newslists { get; set; }
        public int Code { get; set; }
        public string Msg { get; set; }
        public string[] NewsList { get; set; }

    }
