Как бы разобрать этот ответ JSON

Question

Мне нужно разобрать ответ JSON, который связан в нижней части этого сообщения. Я пробовал несколько очень стандартных методов для анализа этого JSON, но я считаю, что это не законный JSON. У кого-нибудь есть решения, которые позволили бы мне разобрать этот JSON?

Отрывок ответа, если вы хотите увидеть, что реальный ответ, это не трудно просто нажмите на ссылку. Мне говорят, что некоторые не могут этого сделать.

Хорошо, так что основы я пытался:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading.Tasks; 
using Newtonsoft.Json; 
using SteamKit2; 
using System.Net; 

namespace SteamTrade 
{ 
    public class CSGOInventory 
    { 
     public static CSGOInventory FetchInventory(string steamId) 
     { 
      WebClient client = new WebClient(); 
      var url = "http://steamcommunity.com/profiles/" + steamId + "/inventory/json/730/2/"; 
      string response = client.DownloadString(url); 
      InventoryResponse result = Newtonsoft.Json.JsonConvert.DeserializeObject<InventoryResponse>(response); 
      return new CSGOInventory(result.result); 
     } 

     public Item[] Items { get; set; } 

     protected CSGOInventory(InventoryResult apiInventory) 
     { 
      Items = apiInventory.items; 
     } 

     public Item GetItem(int id) 
     { 
      return (Items == null ? null : Items.FirstOrDefault(item => item.instanceid == id)); 
     } 

     public List<Item> GetItemsByDefindex(int defindex) 
     { 
      return Items.Where(item => item.def_index == defindex).ToList(); 
     } 

     public class Item 
     { 
      public int AppId = 730; 
      public long ContextId = 2; 

      [JsonProperty("instanceid")] 
      public int instanceid { get; set; } 

      [JsonProperty("market_name")] 
      public string market_name { get; set; } 

      [JsonProperty("def_index")] 
      public int def_index { get; set; } 

     } 

     protected class InventoryResult 
     { 
      public Item[] items { get; set; } 
     } 

     protected class InventoryResponse 
     { 
      public InventoryResult result; 
     } 

    } 
} 

Я получаю ошибку:

Object reference not set to an instance of an object. 

Я получаю ошибку на этой линии:

protected CSGOInventory(InventoryResult apiInventory) 
    { 
     Items = apiInventory.items; 
    } 

I думаю, что мне нужно сериализовать его в словаре, но я не знаете, как реализовать это в моем коде. Может ли кто-нибудь предложить подходящую реализацию в этой ситуации?

Answer 1

Я просто спас JSON от этого веб-сайта в файл, добавили его в качестве ресурса для консольного приложения и следующий код работал отлично

static void Main(string[] args) 
{ 
    string json = Properties.Resources.json; 
    var deserialized = Newtonsoft.Json.JsonConvert.DeserializeObject(json); 
} 

вы либо данные, сохраненные/извлекаться неправильно или с помощью субстандартная библиотека JSON. Попробуйте NewtonSoft JSON

Просмотрев код в обновленном вопросе, я бы предположил, что данные неверны, потому что вы используете другой URL-адрес.
