.Net?Core中如何使用SignalR實現斗地主游戲

本篇內容主要講解“.Net Core中如何使用SignalR實現斗地主游戲”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“.Net Core中如何使用SignalR實現斗地主游戲”吧!

直接上干貨，首先是數據模型：

/// <summary>
    /// 用戶信息
    /// </summary>
    public class Customer
    {
        /// <summary>
        /// 唯一ID
        /// </summary>
        public string? ID { get; set; }

        /// <summary>
        /// 昵稱
        /// </summary>
        public string? NickName { get; set; }

        /// <summary>
        /// 卡片
        /// </summary>
        public List<string> Card { get; set; }
    }


    /// <summary>
    /// 房間
    /// </summary>
    public class Room
    {
        /// <summary>
        /// 房間名
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 房主id
        /// </summary>
        public string Masterid { get; set; }

        /// <summary>
        /// 當前出牌人
        /// </summary>
        public int Curr { get; set; }

        /// <summary>
        /// 當前卡片
        /// </summary>
        public List<string> CurrCard { get; set; } = new List<string>();

        /// <summary>
        /// 當前卡片打出人
        /// </summary>
        public string ExistingCardClient { get; set; }

        /// <summary>
        /// 房間成員列表
        /// </summary>
        public List<Customer> Customers { get; set; } = new List<Customer>();
    }

tips：只是單純為了斗D主設計的，商用版肯定不能這么搞，參考請慎用。

有了數據模型，自然少不了CRUD：

因為所有數據都是通過靜態屬性保存的，所以大部分都是linq操作（原諒我linq水平有限）。

單張規則和普通斗D主一樣（除了王以外2最大，其次是A），多張規則目前支持：王炸、對子、三只、順子、三帶一。目前只做到這里，各位同學可以拿回去自行擴展。
