Question

我正在使用json

{"bloxwich": { "id": 44068310, "name": "Bloxwich", "profileIconId": 663, "revisionDate": 1412456785000, "summonerLevel": 30 }}

但bloxwich将根据用户输入进行更改。

这是我可以用来为bloxwich

访问id的代码

        string result = getResponse("https://na.api.pvp.net/api/lol/na/v1.4/summoner/by-name/" + summonerName + "?api_key=" + key);
        dynamic resultData = JsonConvert.DeserializeObject(result);
        Console.WriteLine(resultData.bloxwich.id);

但是我想知道我每次都能如何进入bloxwich部分，即使这个名字会有所不同。

我尝试使用像这样的for循环

   foreach (var item in resultData)
   {
            Console.WriteLine("Item: " + item[0].id);
   }

但是我收到以下错误：

Answer 1

尝试类似

的内容

using System;
using Newtonsoft.Json.Linq;

JObject resultData = JObject.Parse(result);
foreach (var item in resultData)
{
    Console.WriteLine(item.Key); // this will print "bloxwich" for your example
    Console.WriteLine("Item: " + item.Value.SelectToken("id"));
}

Answer 2

你尝试过这样的事吗？

Dictionary<string, dynamic> data = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(result);
var key = data.Keys.First();
var item = data[key];
Console.WriteLine("Id " + item.id); // here you have the id

我不知道在这种情况下使用字典是否完全正确，但也许它可以帮助你。

需要帮助访问Json对象而不用它的名字C＃
