```c#
Json数据已生成的C#实体类(其中有int类型和string类型)
namespace WindowsFormsApp2
{
public class Root

      /// <summary>

         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

         string getJson = myStreamReader.ReadToEnd();

         Root rt = JsonConvert.DeserializeObject<Root>(getJson); //getjson是字符类型,但是Root类里有int和string类型,该如何修改?
         MessageBox.Show("A=" + rt.lg + "\r\n" + "B=" + rt.e + "\r\n" + "C=" + rt.ps + "\r\n" + "D=" + rt.pt + "\r\n" + "F=" + rt.l); //这样就可以取出json数据里面的值

         for (int i = 0; i < rt.n.Count; i++)  //由于这个JSON字符串的 public List<List<int>> n { get; set; }是一个集合，如何把n遍历int类型
         {
            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
      }

```

Root rt = JsonConvert.DeserializeObject<Root>(getJson); 这行getjson是字符类型,但是Root类里有int和string类型,该如何修改?

for (int i = 0; i < rt.n.Count; i++)  //由于这个JSON字符串的 public List<List<int>> n { get; set; } n是一个集合，如何修改遍历

初接触网站接口返回数据给Json解析并显示,以上两行代码小弟不太懂,望大神们指教.
我使用了Newtonsoft.Json,大神们也可以用LitJson.
