Json.NET - 意外的字符在解析值时遇到： [英] Json.NET - Unexpected character encountered while parsing value:

问题描述

我试图使用蒸汽的Web API来接收JSON和使用JSON.Net解析它。我只是硬编码的网址，让我知道我会得到JSON。我遇到以下错误，当我运行它，但：

I'm trying to use Steam's Web API to receive JSON and parse it using JSON.Net. I'm simply hard-coding a URL where I know I'll receive JSON. I'm running into the following error when I run it though:

在解析值意外遇到性格。路径'，行
  0，位置0。

Unexpected character encountered while parsing value: . Path '', line 0, position 0.

错误指向行我控制器22：

The error points to line 22 of my controller:

第22行：SteamResponse响应= JsonConvert.DeserializeObject（JSON）;

Line 22: SteamResponse response = JsonConvert.DeserializeObject(json);

下面是我的类：

public class Game
{
    public int appid { get; set; }
    public int playtime_forever { get; set; }
    public int? playtime_2weeks { get; set; }
}

public class SteamResponse
{
    public int game_count { get; set; }
    public List<Game> games { get; set; }
}

public class RootObject
{
    public SteamResponse response { get; set; }
}

我的控制器看起来是这样的：

My controller looks like this:

        List<Game> gameList = new List<Game>();

        WebClient wc = new WebClient();

        var json = wc.DownloadString("http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=" + steamAPIKey + "&steamid=76561197994394917&format=json");

        SteamResponse response = JsonConvert.DeserializeObject<SteamResponse>(json);

我所访问过的网址在浏览器中，以验证它是正确的，我还测试了使用JSON皮棉的URL。我不知道我在做什么错在这里 - 我检查了其他议题，并检查他们所列出的问题，但没有发现他们。

I've visited the URL in browser to verify it's correct, and I've also tested the URL using JSON Lint. I'm not sure what I'm doing wrong here - I've checked other topics and checked for the problems they've listed but didn't find them.

Here is a link to the JSON I'm attempting to receive.

推荐答案

您已经创建了一个 RootObject 键入，但你不能在反序列化使用它。您是否尝试过：

You've created a RootObject type, but you're not using it in the deserialization. Have you tried:

var root = JsonConvert.DeserializeObject<RootObject>(json);
// access root.response;
