.Net Core使用SignalR实现斗地主游戏
作者：老马-Max
本文详细讲解了.Net Core使用SignalR实现斗地主游戏的方法，文中通过示例代码介绍的非常详细。对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
之前开内部培训，说到实时web应用这一块讲到了SignalR，我说找时间用它做个游戏玩玩，后面时间紧张就一直没安排。这两天闲了又想起这个事，考虑后决定用2天时间写个斗D主，安排了前端同学写客户端，我写游戏逻辑和服务。
这个项目难度并不高，但是游戏逻辑还是挺绕的，联调过程中也发现解决了很多小问题。来园子里整理一篇文章，记录一下。
基础的介绍就免了，毕竟官网跟着走两圈啥都懂了。没基础的可以戳这里，是我之前写的一篇SignalR基础介绍，带有一个极简聊天室。
tips：文章结尾有开源地址，游戏数据都是本地的，改下IP运行起来就可以玩了。
直接上干货，首先是数据模型：
/// <summary>
/// 用户信息
/// </summary>
public class Customer
{
/// <summary>
/// 唯一ID
/// </summary>
public string? ID { get; set; }
/// <summary>
/// 昵称
/// </summary>
public string? NickName { get; set; }
/// <summary>
/// 卡片
/// </summary>
public List<string> Card { get; set; }
}
/// <summary>
/// 房间
/// </summary>
public class Room
{
/// <summary>
/// 房间名
/// </summary>
public string Name { get; set; }
/// <summary>
/// 房主id
/// </summary>
public string Masterid { get; set; }
/// <summary>
/// 当前出牌人
/// </summary>
public int Curr { get; set; }
/// <summary>
/// 当前卡片
/// </summary>
public List<string> CurrCard { get; set; } = new List<string>();
/// <summary>
/// 当前卡片打出人
/// </summary>
public string ExistingCardClient { get; set; }
/// <summary>
/// 房间成员列表
/// </summary>
public List<Customer> Customers { get; set; } = new List<Customer>();
}tips：只是单纯为了斗D主设计的，商用版肯定不能这么搞，参考请慎用。
有了数据模型，自然少不了CRUD：
/// <summary>
/// 用户操作
/// </summary>
public static class CustomerAction
{
/// <summary>
/// 用户列表
/// </summary>
private static List<Customer> cusList = new List<Customer>();
/// <summary>
/// 不存在则新增，存在则修改昵称
/// </summary>
/// <param name="customer"></param>
public static void Create(Customer customer)
{
Customer curr = null;
if (cusList.Count > 0)
curr = cusList.Where(x => x.ID == customer.ID).FirstOrDefault();
if (curr is null)
cusList.Add(customer);
else
{
curr.NickName = customer.NickName;
Up4ID(curr);
}
}
/// <summary>

}因为所有数据都是通过静态属性保存的，所以大部分都是linq操作（原谅我linq水平有限）。
接下来是游戏逻辑：

}
}单张规则和普通斗D主一样（除了王以外2最大，其次是A），多张规则目前支持：王炸、对子、三只、顺子、三带一。目前只做到这里，各位同学可以拿回去自行扩展。
上一些运行图。房主建房并加入：
新玩家加入：
房间人满以后房主开始游戏，随机分配地主：
出牌特效：
游戏结算：
最后附上开源地址（客户端在web分支）：https://gitee.com/muchengqingxin/card-game
tips：前端同学在没有UI配合的情况下做到现在这样，必须给个赞。最后提醒大家，不要拿去商用。
