需要幫助訪問一個JSON對象，如果沒有它的名字C＃

Question

我使用JSON

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

但是bloxwich會根據用戶輸入改變。

這是代碼，我可以用它來接取該ID只爲bloxwich

 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); 

，但我想弄清楚如何我可以接取的bloxwich部分每次，即使名稱會有所不同。

我試圖用一個for循環這樣

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

，但我得到了以下錯誤：

Answer 1

試着這麼做

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")); 
}

您是否嘗試過這樣的事情？

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 

我不知道在這種情況下使用字典是否完全正確，但也許它可以幫助你。
