如何将大量令人困惑的 .JSON 反序列化为列表框？

Question

我正在与 Json.net 合作，用电影列表（标题、年份和 url 到 medium-image）填充 ListBox 项，这些电影来自这个又长又重的 json代码：

{(...blabla)"movies":[{"id":4120,"url":"https:\/\/yts.to\/movie\/glee-2009","title":"Glee","year":2009,"medium_cover_image":"https:\/\/s.ynet.io\/assets\/images\/movies\/glee_2009\/medium-cover.jpg","state":"ok",}{(...blabla}

问题是，我刚刚开始使用 Json.net 并且对我必须做的事情感到非常困惑。我一直在四处寻找我不理解的代码示例。我可以在这里获取一些用于反序列化该数据的 C# 代码吗：Article article1 = new Article() { Name = "MovieTitle", ImagePath = "URL", Year="0000" };in a loop？

处理这个：

转到 http://json2csharp.com/ 和 post 你的 JSON 那里。
将生成的 classes 复制到 Visual Studio。

JSON 中有一个名为 "@meta" 的命名值，它被转换为以下无效的属性名称：

public Meta __invalid_name__@meta { get; set; }

修复如下：

[JsonProperty("@meta")]
public Meta Metadata { get; set; }

使用 Linq 提取所需数据。

因此：

public class Torrent
{
    public string url { get; set; }
    public string hash { get; set; }
    public string quality { get; set; }
    public int seeds { get; set; }
    public int peers { get; set; }
    public string size { get; set; }
    public long size_bytes { get; set; }
    public string date_uploaded { get; set; }
    public int date_uploaded_unix { get; set; }
}

public class Movie
{
    public int id { get; set; }
    public string url { get; set; }
    public string imdb_code { get; set; }
    public string title { get; set; }
    public string title_long { get; set; }
    public string slug { get; set; }
    public int year { get; set; }
    public double rating { get; set; }
    public int runtime { get; set; }
    public List<string> genres { get; set; }
    public string language { get; set; }
    public string mpa_rating { get; set; }
    public string background_image { get; set; }
    public string small_cover_image { get; set; }
    public string medium_cover_image { get; set; }
    public string state { get; set; }
    public List<Torrent> torrents { get; set; }
    public string date_uploaded { get; set; }
    public int date_uploaded_unix { get; set; }
}

public class Data
{
    public int movie_count { get; set; }
    public int limit { get; set; }
    public int page_number { get; set; }
    public List<Movie> movies { get; set; }
}

public class Meta
{
    public int server_time { get; set; }
    public string server_timezone { get; set; }
    public int api_version { get; set; }
    public string execution_time { get; set; }
}

public class RootObject
{
    public string status { get; set; }
    public string status_message { get; set; }
    public Data data { get; set; }
    [JsonProperty("@meta")]
    public Meta Metadata { get; set; }
}

然后，给定你的 class:

public class Article
{
    public string Name { get; set; }
    public string ImagePath { get; set; }
    public string Year { get; set; }
}

像这样使用它：

        var root = JsonConvert.DeserializeObject<RootObject>(json);
        var articles = root.data.movies.Select(m => new Article { Name = m.title, ImagePath = m.medium_cover_image, Year = m.year.ToString() }).ToList();

        Debug.WriteLine(JsonConvert.SerializeObject(articles, Formatting.Indented));

调试输出为：

[
  {
    "Name": "Glee",
    "ImagePath": "https://s.ynet.io/assets/images/movies/glee_2009/medium-cover.jpg",
    "Year": "2009"
  },
  {
    "Name": "Road Wars",
    "ImagePath": "https://s.ynet.io/assets/images/movies/road_wars_2015/medium-cover.jpg",
    "Year": "2015"
  },
  .... several omitted
]
