c# - 从 JSON 响应中打印特定值

Question

刚开始再次使用 C#，我无法克服这个问题。

我有以下 JSON 内容：

{
  "type": "success",
  "picks": [
    {
      "aftermarket": {
        "domain": "ao38t8u4h.com",
        "fast_transfer": false,
        "price": 0,
        "status": "notfound",
        "type": "",
        "username": ""
      },
      "domain": "ao38t8u4h.com",
      "info": "",
      "priority": 1,
      "status": {
        "available": true,
        "lookupType": "EPP",
        "name": "ao38t8u4h.com",
        "premium": false
      },
      "tld": "com",
      "type": "domain"
    },
    {
      "aftermarket": {
        "domain": "ao38t8u4h.net",
        "fast_transfer": false,
        "price": 0,
        "status": "notfound",
        "type": "",
        "username": ""
      },
      "domain": "ao38t8u4h.net",
      "info": "",
      "priority": 2,
      "status": {
        "available": true,
        "lookupType": "EPP",
        "name": "ao38t8u4h.net",
        "premium": false
      },
      "tld": "net",
      "type": "domain"
    },
    {
      "aftermarket": {
        "domain": "ao38t8u4h.dev",
        "fast_transfer": false,
        "price": 0,
        "status": "notfound",
        "type": "",
        "username": ""
      },
      "domain": "ao38t8u4h.dev",
      "info": "",
      "priority": 3,
      "status": {
        "available": true,
        "lookupType": "EPP",
        "name": "ao38t8u4h.dev",
        "premium": false
      },
      "tld": "dev",
      "type": "domain"
    },
    {
      "aftermarket": {
        "domain": "ao38t8u4h.ai",
        "fast_transfer": false,
        "price": 0,
        "status": "notfound",
        "type": "",
        "username": ""
      },
      "domain": "ao38t8u4h.ai",
      "info": "",
      "priority": 4,
      "status": {
        "available": true,
        "lookupType": "EPP",
        "name": "ao38t8u4h.ai",
        "premium": false
      },
      "tld": "ai",
      "type": "domain"
    },
    {
      "aftermarket": {
        "domain": "ao38t8u4h.org",
        "fast_transfer": false,
        "price": 0,
        "status": "notfound",
        "type": "",
        "username": ""
      },
      "domain": "ao38t8u4h.org",
      "info": "",
      "priority": 5,
      "status": {
        "available": true,
        "lookupType": "EPP",
        "name": "ao38t8u4h.org",
        "premium": false
      },
      "tld": "org",
      "type": "domain"
    }
  ]
}

我想做的是获得["picks"][0]["status"]["premium"]. 我在 Python 中所做的是获取响应，然后简单print(var["picks"][0]["status"]["premium"])地打印值；但是，我不知道如何在 C# 中完成此操作。

我正在使用的代码如下：

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

namespace testing
{
    class Program
    {
        private static readonly HttpClient client = new HttpClient();
        static async Task Main(string[] args)
        {
            try
            {
                string domain = "ao38t8u4h";
                string url = "https://rtb.namecheapapi.com/api/picks/" + domain;
                string responseBody = await client.GetStringAsync(url);
                var json = JsonConvert.DeserializeObject(responseBody);
                Console.WriteLine(json);
                Console.ReadLine();
            }
            catch(HttpRequestException e)
            {
                Console.WriteLine("\nException Caught!");
                Console.WriteLine("Message :{0} ", e.Message);
                Console.ReadLine();
            }
        }
    }
}

Json.Net 支持您习惯使用的语法，如果您使用JTokens.

JToken jt = JToken.Parse(responseBody);
Console.WriteLine(jt["picks"][0]["status"]["premium"]);
