具有无效变量名称的嵌套json

Question

我正在使用c＃中的last.fm api玩。我以前从未使用过JSON，所以这对我来说有点新。

我想解析的JSON看起来像

"{
  "topalbums": {
    "album": [
      {
        "name": "California (Deluxe Edition)",
        "playcount": "89",
        "mbid": "",
        "url": "https: //www.last.fm/music/blink-182/California+(Deluxe+Edition)",
        "artist": {
          "name": "blink-182",
          "mbid": "0743b15a-3c32-48c8-ad58-cb325350befa",
          "url": "https: //www.last.fm/music/blink-182"
        },
        "image": [
          {
            "#text": "https: //lastfm-img2.akamaized.net/i/u/34s/ccd85fcfa4370e1df83a67c7fa79096c.png",
            "size": "small"
          },
          {
            "#text": "https: //lastfm-img2.akamaized.net/i/u/64s/ccd85fcfa4370e1df83a67c7fa79096c.png",
            "size": "medium"
          },
          {
            "#text": "https: //lastfm-img2.akamaized.net/i/u/174s/ccd85fcfa4370e1df83a67c7fa79096c.png",
            "size": "large"
          },
          {
            "#text": "https: //lastfm-img2.akamaized.net/i/u/300x300/ccd85fcfa4370e1df83a67c7fa79096c.png",
            "size": "extralarge"
          }
        ],
        "@attr": {
          "rank": "1"
        }
      },

我的代码供应JSON看起来像

public List<TopAlbum> GetTopAlbumsDeserialized(int limit)
        {
            List<TopAlbum> topAlbumList = new List<TopAlbum>();
            var request = (HttpWebRequest)WebRequest.Create(
                webServiceURL + "/2.0/?method=user.gettopalbums&user=" + user + "&api_key=" + key + "&format=json");
            if (limit > 0)
            {
                request = (HttpWebRequest)WebRequest.Create(
                    webServiceURL + "/2.0/?method=user.gettopalbums&user=" + user + "&limit=" + limit
                    + "&api_key=" + key + "&format=json");
            }
            request.ContentType = "application/json; charset=utf-8";
            request.Method = WebRequestMethods.Http.Get;
            request.Accept = "application/json";
            var response = (HttpWebResponse)request.GetResponse();
            using (var sr = new StreamReader(response.GetResponseStream()))
            {
                string responseString = sr.ReadToEnd();
                sr.Close();
                JContainer jContainer = JObject.Parse(responseString);
                JArray topAlbumsArray = JArray.FromObject(jContainer.First().First().First().First());
                JObject.FromObject(jContainer.First().First().First().First()["image"]);
                topAlbumList = JsonConvert.DeserializeObject<List<TopAlbum>>(topAlbumsArray.ToString());
            }
            return topAlbumList;
        }

我的代码对专辑的认可似乎最初可以正常工作。但是，当我查看返回的列表时，对于每个专辑对象，我的图像列表为空，等级变量为null。

我编写了代码，该代码将导航到JSON中的专辑数组，而只是解析每张专辑，但看起来不太好。我不认为我已经为图像和topalbum课程正确编写了jsonpropertys。

这是我的对象供参考。

public class Album
    {
        public string name { get; set; }
        public string playcount { get; set; }
        public string mbid { get; set; }
        public string url { get; set; }
        public Artist artist { get; set; }
        public List<Image> images { get; set; }
    }
public class TopAlbum : Album
    {
        public string rank { get; set; }
    }
public class Image
    {
        [JsonProperty("#text")]
        public string text {get; set;}
        public string size { get; set; }
    }
public class Artist
    {
        public string name { get; set; }
        public string mbid { get; set; }
        public string url { get; set; }
    }

使用此站点，您的模型应该像这样

public class Artist
{
    public string name { get; set; }
    public string mbid { get; set; }
    public string url { get; set; }
}
public class Image
{
    [JsonProperty("#text")]
    public string text { get; set; }
    public string size { get; set; }
}
public class Attr
{
    public string rank { get; set; }
}
public class Album
{
    public string name { get; set; }
    public string playcount { get; set; }
    public string mbid { get; set; }
    public string url { get; set; }
    public Artist artist { get; set; }
    public List<Image> image { get; set; }
    [JsonProperty("@attr")]
    public Attr attr { get; set; }
}
public class Attr2
{
    public string user { get; set; }
    public string page { get; set; }
    public string perPage { get; set; }
    public string totalPages { get; set; }
    public string total { get; set; }
}
public class Topalbums
{
    public List<Album> album { get; set; }
    [JsonProperty("@attr")]
    public Attr2 attr { get; set; }
}
public class RootObject
{
    public Topalbums topalbums { get; set; }
}

您现在可以作为

进行挑选

var result = JsonConvert.DeserializeObject<RootObject>(json);
