我有一个大json文件，只想使用某些嵌套属性，这是文件

{
 "type": "champion",
 "format": "standAloneComplex",
 "version": "6.24.1",
 "data": {
    "Aatrox": {
        "version": "6.24.1",
        "id": "Aatrox",
        "key": "266",
        "name": "Aatrox",
        "title": "the Darkin Blade",
        "blurb": "Aatrox is a legendary warrior, one of only five that remain of an ancient race known as 
         the Darkin. He wields his massive blade with grace and poise, slicing through legions in a style 
         that is hypnotic to behold. With each foe felled, Aatrox's ...",
        "info": {
          "attack": 8,
          "defense": 4,
          "magic": 3,
          "difficulty": 4
        },
        "image": {
          "full": "Aatrox.png",
          "sprite": "champion0.png",
          "group": "champion",
          "x": 0,
          "y": 0,
          "w": 48,
          "h": 48
        },
        "tags": [
          "Fighter",
          "Tank"
        ],
    },
    "Ahri": {
        "version": "6.24.1",
        "id": "Ahri",
        "key": "103",
        "name": "Ahri",
        "title": "the Nine-Tailed Fox",
        "blurb": "Unlike other foxes that roamed the woods of southern Ionia, Ahri had always felt a 
            strange connection to the magical world around her; a connection that was somehow incomplete.

          "info": {
             "attack": 3,
             "defense": 4,
             "magic": 8,
             "difficulty": 5
           },
           "image": {
              "full": "Ahri.png",
              "sprite": "champion0.png",
              "group": "champion",
              "x": 48,
              "y": 0,
              "w": 48,
              "h": 48
            },
            "tags": [
               "Mage",
               "Assassin"
            ],
      },

这是一个很长的json文件。我有一堂课是

public class Champion
{
    public string id { get; set; }
    public string key { get; set; }
    public string name { get; set; }
    public string title { get; set;}
}
public class ChampionRoot
{
    public Dictionary<string, Champion> champions { get; set; }
}

我想做的是从“数据”中的属性开始，只将“id”、“key”、“name”和“title”以及Deserialize这些属性放入我的ChampionRoot类中。我已经搜索并尝试了很多东西，但无法让它发挥作用。这是我在控制器中尝试过的一些内容

public IActionResult Champions()
{
    var url = @"url.......";
    WebClient client = new WebClient();

    var download = client.DownloadString(url);

    var champions = Newtonsoft.Json.JsonConvert.DeserializeObject<ChampionRoot>(download);

    return Json(champions);    //This returns null in the view
}

我也尝试过使用JObject几种不同的方法，但这对我也不起作用

JObject obj = JObject.Parse(download);
var json = obj["key"]["id"]["name"]["title"];    //throws object reference error

然后我试过这个

JObject obj = JObject.Parse(download);
var champions = Newtonsoft.Json.JsonConvert.DeserializeObject<ChampionRoot>(obj.ToString());
//This also returns null in the view

我已经搜索并阅读了很多答案，但我无法弄清楚。问题是我怎样才能只Deserialize将这 4 个嵌套属性放入一个对象中？完整文件的网址是http://ddragon.leagueoflegends.com/cdn/6.24.1/data/en_US/champion.json 。json

您可以Dictionary<string, Champion>用于data财产：

public class ChampionRoot
{
    public Dictionary<string,Champion> data { get; set; }
}
var champions = Newtonsoft.Json.JsonConvert.DeserializeObject<ChampionRoot>(download);
