C＃抽搐類總是存儲null

Question

所以我是一個自學成才的C＃程序員。我對C＃的所有知識都來自於在學校學習Java並將其應用於C＃。我對類的瞭解並不是很好，使用JSON數據幾乎完全沒有。所以我有這個JSON數據，我從一個HttpWebClient下拉，然後使用JSON.NET反序列化它。我爲類結構使用了json2csharp類生成器。不過，我相信丟失一個導致對象只對所有內容都爲空的步驟。

例JSON數據 https://github.com/justintv/Twitch-API/blob/master/v3_resources/games.md GET /遊戲/頂部示例數據

我的代碼

var client = new HttpClient(); 
var url = new Uri("https://api.twitch.tv/kraken/games/top"); 
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/vnd.twitchtv.v3+json")); 
var response = await client.GetAsync(url); 
var content = await response.Content.ReadAsStringAsync(); 
TwitchReturn objectHolder = JsonConvert.DeserializeObject<TwitchReturn>(content); 
Console.WriteLine(objectHolder); 

^這應該具有objectHolder.top [0] .game.name;我只是不知道如何訪問這個。

抽搐返回分類

class TwitchReturn 
{ 
    public class Links 
    { 
     public string self { get; set; } 
     public string next { get; set; } 
    } 

    public class Box 
    { 
     public string large { get; set; } 
     public string medium { get; set; } 
     public string small { get; set; } 
     public string template { get; set; } 
    } 

    public class Logo 
    { 
     public string large { get; set; } 
     public string medium { get; set; } 
     public string small { get; set; } 
     public string template { get; set; } 
    } 

    public class Links2 
    { 
    } 

    public class Game 
    { 
     public string name { get; set; } 
     public int _id { get; set; } 
     public int giantbomb_id { get; set; } 
     public Box box { get; set; } 
     public Logo logo { get; set; } 
     public Links2 _links { get; set; } 
    } 

    public class Top 
    { 
     public int viewers { get; set; } 
     public int channels { get; set; } 
     public Game game { get; set; } 
    } 

    public class RootObject 
    { 
     public int _total { get; set; } 
     public Links _links { get; set; } 
     public List<Top> top { get; set; } 
    } 

} 

我相信，我在做什麼錯誤從類和控制檯聲明來臨的時候，我只是不知道，足以做到這一點。儘管我知道這很可能非常簡單。

僅當.Net實體與傳入的JSON數據明顯匹配時，纔可以將JSON轉換爲.NET對象反序列化。在這裏，您不必創建嵌套類，而必須創建TwitchReturn類，並根據數據決定屬性，以及它是否會收集。

class TwitchReturn 
{ 
    public Links _links { get; set; } 
    public IEnumerable<Top> top { get; set; } 
    public RootObject rootObject { get; set; } 
} 

public class Links 
{ 
    public string self { get; set; } 
    public string next { get; set; } 
} 

public class Box 
{ 
    public string large { get; set; } 
    public string medium { get; set; } 
    public string small { get; set; } 
    public string template { get; set; } 
} 

public class Logo 
{ 
    public string large { get; set; } 
    public string medium { get; set; } 
    public string small { get; set; } 
    public string template { get; set; } 
} 

public class Links2 
{ 
} 

public class Game 
{ 
    public string name { get; set; } 
    public int _id { get; set; } 
    public int giantbomb_id { get; set; } 
    public Box box { get; set; } 
    public Logo logo { get; set; } 
    public Links2 _links { get; set; } 
} 

public class Top 
{ 
    public int viewers { get; set; } 
    public int channels { get; set; } 
    public Game game { get; set; } 
} 

public class RootObject 
{ 
    public int _total { get; set; } 
    public Links _links { get; set; } 
    public List<Top> top { get; set; } 
}
