我可以在对象的 New() 构造函数中声明委托吗？还是带初始化参数？

Question

我试图在 C# 中声明一个与我的数据内联的委托，但它似乎无法编译。我希望有人可以帮助我（重新）构建我的想法或我的代码。

我的目标是在在线游戏中创建不同的玩家类型。每种玩家类型都有他们采用的策略。通过调用内联异步函数来采用此策略，该函数可能调用 HTTP REST 资源作为 IQueryable 评估的一部分。

问题：

为每个 AIPlayer 类型配置 EvaluateTurn() 委托中所需代码的可维护方法是什么？

将添加更多播放器类型，IQueryable 将成为针对 CosmosDB、AzureTable、SQL、内存数组等的延迟执行 Linq 查询

public class AIPlayer
{
    public string PlayerPersonaName { get; set; }
    public string Description { get; set; }

    public delegate int EvaluateTurn(IQueryable<GameplayRound> playHistory);
}


public List<AIPlayer> CreateDefaultPersonas()
{
    var ret = new List<AIPlayer>();

    ret.Add(new AIPlayer()
    {
        PlayerPersonaName = "CopyCat" ,
        Description = "Hello! I start with Cooperate, and afterwards, I just copy whatever you did in the last round. Meow",
    });

    ret.Add(new AIPlayer() {
        PlayerPersonaName = "Grudger" ,
         Description = "Listen, pardner. I'll start cooperatin', and keep cooperatin', but if y'all ever cheat me, I'LL CHEAT YOU BACK 'TIL THE END OF TARNATION."
    });

    ret.Add(new AIPlayer() {
        PlayerPersonaName = "AlwaysCheat",
        Description = "the strong shall eat the weak"
    });

   ret.Add(new AIPlayer() {
       PlayerPersonaName = "AlwaysCooperate",
       Description = "Let's be best friends! <3"
   });

   ret.Add(new AIPlayer() {
       PlayerPersonaName = "Detective",
       Description = "First: I analyze you. I start: Cooperate, Cheat, Cooperate, Cooperate. If you cheat back, I'll act like Copycat. If you never cheat back, I'll act like Always Cheat, to exploit you. Elementary, my dear Watson."
    });

    ret.Add(new AIPlayer()
    {
        PlayerPersonaName = "CopyKitten",
        Description = "Hello! I'm like Copycat, except I Cheat back only after you Cheat me twice in a row. After all, the first one could be a mistake! Purrrrr",
    });

    ret.Add(new AIPlayer()
    {
        PlayerPersonaName = "Simpleton",
        Description = "hi i try start cooperate. if you cooperate back, i do same thing as last move, even if it mistake. if you cheat back, i do opposite thing as last move, even if it mistake.",
    });

    ret.Add(new AIPlayer()
    {
        PlayerPersonaName = "Random",
        Description = "Monkey robot! Ninja pizza tacos! lol i'm so random (Just plays Cheat or Cooperate randomly with a 50 / 50 chance)",
    });
   return ret;
}

委托是一种类型，您需要声明该类型的属性：

public class AIPlayer
{
    public string PlayerPersonaName { get; set; }
    public string Description { get; set; }
    public EvaluateTurn Evaluation { get; set; }

    public delegate int EvaluateTurn(IQueryable<GameplayRound> playHistory);
}

然后：

new AIPlayer()
{
    PlayerPersonaName = "CopyCat" ,
    Description = "Hello! I start with Cooperate, and afterwards, I just copy whatever you did in the last round. Meow",
    Evaluation = playHistory => 1
};

或者为了简洁起见，您可以只使用 Func：

public class AIPlayer
{
    public string PlayerPersonaName { get; set; }
    public string Description { get; set; }
    public Func<IQueryable<GameplayRound>, int> Evaluation { get; set; }
}

我可以在对象的 New() 构造函数中声明委托吗？还是带初始化参数？

Can I declare a delegate in an Object's New() constructor? Or with initialization parameters?
