Question

我在反序列化以下JSON字符串时遇到了一些问题。在我的所有其他回复中，它的效果非常好但不适用于此。我尝试了很多不同的东西，我检查了Stream类大约100次。我也使用了json2csharp中生成的类，但我的所有反序列化数据都是NULL。

获取回复的代码：

    public Stream getStream(string userID)
    {
        var request = GetRequest("streams/{channelID}", Method.GET);
        request.AddUrlSegment("channelID", userID);
        var response = restClient.Execute<Stream>(request);
        return response.Data;
    }

response.Content向我展示了类似的例子：

{
"stream":
    {
    "_id":25649270464,
    "game":"test",
    "broadcast_platform":"other",
    "community_id":"xxxxxxxxx",
    "community_ids":["xxxxxx"],
    "viewers":2421,
    "video_height":1080,
    "average_fps":61.7876424715,
    "delay":0,
    "created_at":"2017-07-02T10:01:28Z",
    "is_playlist":false,

        "medium":"https://static-cdn.jtvnw.net/previews-ttv/live_user_lostaiming-320x180.jpg",
        "large":"https://static-cdn.jtvnw.net/previews-ttv/live_user_lostaiming-640x360.jpg",
        "template":"https://static-cdn.jtvnw.net/previews-ttv/live_user_lostaiming-{width}x{height}.jpg"
        },
    "channel":
        {
        "mature":false,
        "status":"Test"
        ,"broadcaster_language":"de",
        "display_name":"LOSTAIMING",
        "game":"test",
        "language":"en",
        "_id":44281267,
        "name":"lostaiming",
        "created_at":"2013-06-02T16:42:19.329009Z",
        "updated_at":"2017-07-02T13:05:11.555285Z",
        "partner":true,
        "logo":"https://static-cdn.jtvnw.net/jtv_user_pictures/lostaiming-profile_image-e9d7ea0893748d6a-300x300.png",
        "video_banner":"https://static-cdn.jtvnw.net/jtv_user_pictures/cc34c6b909a435ae-channel_offline_image-1920x1080.png",
        "profile_banner":"https://static-cdn.jtvnw.net/jtv_user_pictures/c187e8871c0f6a2b-profile_banner-480.png",
        "profile_banner_background_color":"",
        "url":"https://www.twitch.tv/lostaiming",
        "views":2292173,
        "followers":55672,
        "broadcaster_type":"",
        "description":"Blubb"
        }
    }
}

Answer 1

1）使用JSON Utils（https://jsonutils.com/）生成C＃类（对于属性选择JsonProperty）

2）Newtonsoft.Json几乎是使用.NET中JSON格式的标准最佳库，你可以从nuget获得它。

3）代码应该看起来像这样，反序列化应该没有任何问题：

    class Program
    {
        private static void Main(string[] args)
        {
            var myObj = JsonConvert.DeserializeObject<JsonDef>(json);

            Console.Read();
        }
    }

    public class Preview

        public Stream stream { get; set; }
    }

Answer 2

这是因为JSON的DateTime格式。它不是一个格式良好的.Net DateTime。所以你可以把它作为一个字符串，然后按你想要的方式转换它或将其格式改为可读的.Net格式。

坚持反序列化JSON Web响应
