将不同的命名对象反序列化为一个集合

本文关键字：集合 一个 反序列化 对象 | 更新日期: 2023-09-27 18:18:50

我必须读取一个给定的JSON字符串到c#对象。到目前为止还好，但这个案子对我来说有点特殊。JSON字符串包含2个实体。一个是平面对象，另一个是列表，至少合乎逻辑，但不是真正的JSON。我希望你能帮我找到一个解决办法。

为了更好地解释它，我将向您展示我的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"}
}

我想把玩家实体序列化成这个类型的对象集合。问题是它们并没有真正以JSON的集合形式存储。它们的动态名称为"player_56"，数字没有任何逻辑顺序，如"1,2,3"。

目前我正在使用DataContractJsonSerializer来完成这项任务。

[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?

将不同的命名对象反序列化为一个集合

我不知道DataContractJsonSerializer的范围，但可能有一个接口，你可以实现你的类来定义如何解析JSON。

但是如果你能够使用JSON。净:

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

然后可以使用Linq-To-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JSON分解为玩家对象集合

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


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

如何处理JSON，一个RegEx可能就足够了。

EDIT下面是使用Regex进行字符串修改的代码。我们做了一些假设:在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);

与所有关于速度的考虑一样，您必须对其进行测试，如果我必须优化上述内容，那么将Regex对象作为静态和可重用的将是我的第一步。
