JSON将不同的命名对象反序列化为一个集合c＃

Question

我必须将给定的JSON字符串读入C＃对象。到目前为止这么好，但这种情况对我来说很特别。 JSON字符串包含2个实体。一个是平面对象，第二个是列表，至少符合逻辑，但不是真正的JSON。我希望你能帮我找到解决办法。

为了更好地解释它，我会告诉你我的JSON输入的一部分：

{ 
"game":{"GameMode":"1","IsNetworkMode":"1","NbMaxPlayer":"12","GameState":"1"}, 

"player_56":{"PlayerUserId":"137187","PlayerIALevel":"-1","PlayerObserver":"0"}, 
"player_7":{"PlayerUserId":"3440","PlayerIALevel":"-1","PlayerObserver":"0"} 
} 

我想给玩家的实体序列化到这种类型的对象的集合。问题在于它们实际上不是以JSON形式存储为集合。他们的动态名称为“player_56”，并且数字不是像“1,2,3”这样的任何逻辑顺序。

目前我正在使用DataContractJsonSerializer来完成此任务。

[DataContract] 
public class AlbReplay 
{ 
    [DataMember(Name = "game")] 
    public AlbGame Game { get; set; } 
    [DataMember(Name = "player")] 
    public List<AlbPlayer> Players { get; set; } 
} 

有什么建议吗？

我不知道DataContractJsonSerializer的范围，但可能有一个接口可以在您的类上实现以定义如何解析JSON。

但是，如果你能使用JSON.Net：

public class Player 
{ 
    public int Id { get; set; } 
    public int PlayerUserId { get; set; } 
    public int PlayerIALevel { get; set; } 
    public int PlayerObserver { get; set; } 
} 

然后你可以使用LINQ到JSON：

var data = @"{ 
""game"":{""GameMode"":""1"",""IsNetworkMode"":""1"",""NbMaxPlayer"":""12"",""GameState"":""1""}, 

""player_56"":{""PlayerUserId"":""137187"",""PlayerIALevel"":""-1"",""PlayerObserver"":""0""}, 
""player_7"":{""PlayerUserId"":""3440"",""PlayerIALevel"":""-1"",""PlayerObserver"":""0""} 
}"; 

JObject o = JObject.Parse(data); 

IEnumerable<Player> players = 
    o.Children() 
    .Where(p => ((JProperty)p).Name.StartsWith("player")) 
    .Select(p => 
     new Player 
     { 
      Id = int.Parse(((JProperty)p).Name.Split('_')[1]), 
      PlayerUserId = int.Parse((string)p.Children<JObject>().First()["PlayerUserId"]), 
      PlayerIALevel = int.Parse((string)p.Children<JObject>().First()["PlayerIALevel"]), 
      PlayerObserver = int.Parse((string)p.Children<JObject>().First()["PlayerObserver"]), 
     });

将你的JSON压入玩家对象的集合。

player_8: {...} 
player_99: {...} 

到

players: [ 
    {id: 8 ...}, 
    {id: 99 ...} 
] 

如何裂伤您的JSON，正则表达式将可能足以。

编辑下面是使用Regex进行字符串变形的代码。有一些假设：游戏和玩家对象中没有嵌入对象，玩家对象列表是JSON字符串的最后一部分。

 string json_test = @"{ 
""game"":{""GameMode"":""1"",""IsNetworkMode"":""1"",""NbMaxPlayer"":""12"",""GameState"":""1""}, 
""player_56"" : {""PlayerUserId"":""137187"",""PlayerIALevel"":""-1"",""PlayerObserver"":""0""}, 
""player_2"": {""PlayerUserId"":""137187"",""PlayerIALevel"":""-1"",""PlayerObserver"":""0""} 
}"; 
     json_test = new Regex(@"""player_(\d+)""\s*:\s*{").Replace(json_test, @"""player"" : {""Id"": $1,"); 
     Console.WriteLine("player_##:{...} -> player:{id: ##,..}"); 
     Console.WriteLine(json_test); 
     json_test = new Regex(@"""player""\s*:\s*{").Replace(json_test, @"""players"" : [{", 1); 
     json_test = new Regex(@"""player""\s*:\s*{").Replace(json_test, @"{"); 
     json_test = new Regex(@"}$").Replace(json_test, @"]}"); 
     Console.WriteLine("player:{...}, -> players: [{...},...]"); 
     Console.WriteLine(json_test); 

与速度方面都考虑，你必须对它进行测试，具有regex对象静态和可重复使用的将是我的第一步，如果我不得不优化上面。
