c# - 复杂数据模型和json.net序列化问题

Question

我有以下数据模型

class Tournament{
    int Id { get; set;}
    ICollection<League> Leagues { get; set;}
}

class League{
    int Id {get;set;};
    Tournament Parent { get; set;}
    ICollection<Player> Players { get; set;}
    ICollection<Round>  { get; set;}
}
 class Player{
    int Id  { get; set;}
     League Parent  { get; set;}
     ICollection<Game> Games { get; set;}
 }
 class Round{
    int Id  { get; set;}
    ICollection<Game> Games { get; set;}
    League Parent  { get; set;}
}

class Game{
 int Id { get; set;}
 Player playerOne { get; set;}
 Player playerTwo  { get; set;}
 Round Parent { get; set;}
}

我在使用 json.net newtsoft 进行序列化和反序列化时遇到了问题。

我得到以下文件 https://api.myjson.com/bins/1aa4kl

使用以下 JSON 网络设置

  JsonConvert.DefaultSettings = () => new JsonSerializerSettings
      {
        DateTimeZoneHandling = DateTimeZoneHandling.Local,
        TypeNameHandling = TypeNameHandling.Objects,
        Formatting = Formatting.Indented,
        ReferenceLoopHandling = ReferenceLoopHandling.Serialize,
        PreserveReferencesHandling = PreserveReferencesHandling.Objects,
        };

但是正如您从输出文件中看到的那样，它是不正确的，我希望游戏存储对玩家和游戏的引用，但它没有正确引用它们。并且在反洗钱时，除了联赛到锦标赛之外，没有任何父子关系被映射。

我没有任何类的数据属性。

谁能告诉我出了什么问题？我需要更改数据模型吗？

谢谢

我设法得到了一个工作模型:

public class JsonRoot
{
    [JsonProperty("$id")]
    public string Id_X { get; set; }
    [JsonProperty("$type")]
    public string Type_X { get; set; }
    public bool UploadedToDatabase { get; set; }
    public string Id { get; set; }
    public bool TournamentStarted { get; set; }
    public int MaximumNumberOfRounds { get; set; }
    public string Name { get; set; }
    public League[] Leagues { get; set; }
    public object SaveFilePath { get; set; }
    public object SavedFileName { get; set; }
    public object DefaultPairingMethod { get; set; }
    public int DefaultPairingLag { get; set; }
    public bool IsTournamentRanked { get; set; }
    public string UserId { get; set; }
    public object StreamUrl { get; set; }
    public string StartTime { get; set; }
    public string EndTime { get; set; }
    public int NumberOfPlacesForPrizes { get; set; }
    public bool isTournamentDirector { get; set; }
}

[JsonProperty("$id")] 在这里是必需的，因为 $ 在属性名中是不允许的!

{
    [JsonProperty("$id")]
    public string ID_X { get; set; }
    [JsonProperty("$type")]
    public string Type_X { get; set; }
    public bool UploadedToDatabase { get; set; }
    public string Id { get; set; }
    public object Name { get; set; }
    public int NumberOfRounds { get; set; }
    public object Parent { get; set; }
    public Player[] Players { get; set; }
    public Round[] Rounds { get; set; }
    public bool LeagueStarted { get; set; }
    public object Prizes { get; set; }

    public string Id { get; set; }
    public object Parent { get; set; }
    public List<Game> Games { get; set; }

    public double NumberOfWins { get; set; }
    public double NumberOfDraws { get; set; }
    public double NumberOfLosses { get; set; }
    public int Spread { get; set; }
    public string FullName { get; set; }
    public bool IsSelected { get; set; }      
}

我试图像这样解决“ parent ”问题，但它没有序列化:

public class Reference
{
    [JsonProperty("$ref")]
    public string ref_id { get; set; }
}

但我最终使用了 object...

我相信这可以改进，但它应该告诉你前进的方向:D

你可以用 Guid 和其他东西替换 string Id

对于调试，我建议在类中添加一些override ToString()。

这样测试:

var test = JsonConvert.DeserializeObject<JsonRoot>(json);
