将某些嵌套属性反序列化为类

Question

我有一个大的json文件，只想使用某些嵌套属性，这里是文件

{
"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. 
Deep inside, she felt the skin she had been born into was an ill fit for ...",
"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。我有一个类是

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; }
}

我试图做的是从"数据"中的属性开始，只得到"id"，"key"，"name"和"title"，并将这些属性Deserialize到我的ChampionRoot类中。我已经搜索并尝试了很多东西，但无法让它工作。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
}

我也尝试了几种不同的方式使用JObject但这对我来说也不起作用

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许多答案，但我无法弄清楚。问题是我怎么能只Deserialize这 4 个嵌套属性到一个对象中？http://ddragon.leagueoflegends.com/cdn/6.24.1/data/en_US/champion.json 完整json文件的 url

Answer 1

您可以将Dictionary<string, Champion>用于data属性：

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