json.net json c#

    我想从JSON数组中获取多个项的字符串/整数,但我真的不知道如何实现这一点 

    static void Main(string[] args)
        {
            Console.WriteLine(jsonRequest("Râsu", "Aegwynn", "mythic_plus_best_runs").SelectToken("mythic_plus_best_runs"));
            Console.ReadKey();
        }

        public static dynamic jsonRequest(String playerName, String realmName, String requestField)
        {
            String json = new WebClient().DownloadString("https://raider.io/api/v1/characters/profile?region=eu&realm=" + realmName + "&name=" + playerName + "&fields=" + requestField);
            dynamic liste = JsonConvert.DeserializeObject(json);
            return liste;
        }

    using Newtonsoft.Json;
using System;
using System.Net;

    在这个项目中得到了应用

    我想为每一件物品提取“地下城”和“钥匙级别”字符串/int,但当我这么做时 

    Console.WriteLine(jsonRequest("Râsu", "Aegwynn", "mythic_plus_best_runs").SelectToken("mythic_plus_best_runs.dungeon"));

    它只是扔

    密钥“mythic_plus_best_runs”的值是一个数组。

    所以,你必须循环它来获得所有的“地牢”值。 

    var result = jsonRequest("Râsu", "Aegwynn", "mythic_plus_best_runs");

foreach (var item in result["mythic_plus_best_runs"])
{
    Console.WriteLine(item["dungeon"]);
}
