Question

我需要解析在这篇文章底部链接的JSON响应。我已经尝试了几种非常标准的方法来解析这个JSON，但我认为它不是合法的JSON。有没有人有任何解决方案可以让我解析这个JSON？

回复片段，如果您想要查看实际响应并不困难，只需点击该链接即可。有些人不能这样做，我告诉你。

好吧，所以我尝试过的基础知识：

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;
        }

    }
}

我得到错误：

Object reference not set to an instance of an object.

我在这一行得到错误：

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

我认为我需要将其序列化为字典，但我不确定如何将其实现到我的代码中。在这种情况下，有人能建议合适的实施吗？

Answer 1

我刚从该网站将json保存到文件中，将其作为资源添加到控制台应用程序中，以下代码正常运行

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

您要么保存/检索数据不正确，要么使用不合标准的JSON库。试试NewtonSoft JSON

查看更新后问题中的代码后，我猜测数据不正确，因为您使用的是其他网址。

http://steamcommunity.com/的配置文件 /＆＃34; + steamId +＆＃34; / inventory / json / 730/2 / http://steamcommunity.com/的 ID / Mambocsgoshack /库存/ JSON / 730/2 /

我将如何解析此JSON响应
