C#如何用Newtonsoft.Json获取[]中括号内多层[]中括号里的数据并显示在text里?

Json格式化

Json转C#实体类

在类单元里把int改成了string字符串

提示错误

代码如下:
json已转的C#实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WindowsFormsApp3
{
    public class Root
    {
        public List> l { get; set; }
        public List> n { get; set; }
    }

}

using Newtonsoft.Json;  //引入这个库
using System.Net;   //HttpWebRequest
using System.IO;    //Stream流

private void button1_Click(object sender, EventArgs e)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(@"https://phoile.tender88.com/sports-service/sv/odds/events?mk=1&sp=29&ot=2&btg=1&o=1&lg=&ev=&d=&l=100&v=0&me=0&more=false&c=CN&tm=0&g=QQ%3D%3D&pa=0&cl=100&_g=1&pimo=0%2C1%2C8%2C3%2C6%2C7%2C4%2C5&inl=false&_=1671623147061&locale=zh_CN"));
            request.Method = "GET";  //请求的方法
            request.Accept = "application/json, text/javascript, */*; q=0.01"; //可以接受哪些类型的文件
            request.Headers.Add("Accept-Language", "zh-CN,zh;q=0.9"); //头部信息添加语言
            request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36"; //访问验证
            request.ContentType = "application/json;charset=UTF-8"; //识别编码格式UTF-8
            HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //响应,强制转换
            Stream myResponseStream = response.GetResponseStream();   //获取流,需要引用命名空间IO
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);  //流读取器,观察者模式
            //textBox1.Text = myStreamReader.ReadToEnd();   //读取放到text里

        //以下代码是json
            string getJson = myStreamReader.ReadToEnd();
            Root rt = JsonConvert.DeserializeObject(getJson);   //传入实体类还有需要解析的JSON字符串这样就OK了。然后就可以通过实体类使用数据了。 

           for (int i = 0; i < rt.l.Count; i++)  //由于public List> l { get; set; }是一个集合，所以需要遍历集合里面的所有数据
            {
                textBox1.Text = ("A=" + rt.l[i]);
                //MessageBox.Show("Data=" + rt.data[i].context + "\r\n" + rt.data[i].location + "\r\n" + rt.data[i].time + "\r\n" + rt.data[i].ftime);
            }
            myStreamReader.Close();     //关闭
            myStreamReader.Dispose();   //释放
            myResponseStream.Close();   //关闭流
            myResponseStream.Dispose(); //释放流
        }

C#如何用Newtonsoft.Json获取[]中括号内多层[]中括号里的数据并显示在text里?

1、使用Newtonsoft.Json的DeserializeObject方法将json字符串反序列化为对象：

string json = "";  //json字符串
var result = JsonConvert.DeserializeObject<List<Dictionary<string,string>>>(json);

2、使用foreach循环遍历每一层的[]中括号内的数据，将其加入到字符串中：

string str = "";
foreach (var item1 in result)
{
    foreach (var item2 in item1)
    {
        str +=item2.Key +":"+item2.Value;
    }
}

3、将获取到的字符串赋值给text控件：

text.Text = str;
