C# 扫雷 C#带你玩扫雷（附源码）
Cosecant 人气:0想了解C#带你玩扫雷（附源码）的相关内容吗，Cosecant在本文为您仔细讲解C# 扫雷的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：C#,扫雷，下面大家一起来学习吧。
扫雷游戏，大家都应该玩过吧！其实规则也很简单，可是我们想自己实现一个扫雷，我们应该怎么做呢？
Step1: 知晓游戏原理
扫雷就是要把所有非地雷的格子揭开即胜利；踩到地雷格子就算失败。游戏主区域由很多个方格组成。使用鼠标左键随机点击一个方格，方格即被打开并显示出方格中的数字；方格中数字则表示其周围的8个方格隐藏了几颗雷；如果点开的格子为空白格，即其周围有0颗雷，则其周围格子自动打开；如果其周围还有空白格，则会引发连锁反应；在你认为有雷的格子上，点击右键即可标记雷；如果一个已打开格子周围所有的雷已经正确标出，则可以在此格上同时点击鼠标左右键以打开其周围剩余的无雷格。
1代表1的上下左右及斜角合计有一颗雷，依次轮推，2则有2颗，3则有3颗..
在确实是炸弹的方格上点了旗子，就安全了，不是炸弹的被点了旗子，后面会被炸死的..问号就先不确定这里有没有炸弹，不会存在点错了被炸死的状况..
Step2: 由step1可知，游戏由格子组成，翻译成代码语言就叫做数组，也就是游戏地图就是一个二维数组。格子对象，格子的值即当前雷的数量，那么此时我们暂定雷的数字标识为-1。除此之外，格子对象还有是否被显示，显示当前雷数量等属性，那么我们大概可以定义这样一个类：
public class CellBlockRole
{
/// <summary>
/// 位于游戏地图中的坐标点X
/// </summary>
public int X { get; set; }
/// <summary>
/// 位于游戏地图中的坐标点Y
/// </summary>
public int Y { get; set; }
/// <summary>
/// 是否展示最后格子所代表的结果
/// </summary>
public bool IsShowResult { get; set; } = false;
/// <summary>
/// 是否计算数字结果
/// </summary>
public bool IsComputeResult { get; set; } = false;
/// <summary>
/// 是否已经展示过计算结果了
/// </summary>
public bool IsHasShowComputed { get; set; } = false;
/// <summary>
/// 当前的格子的角色数字， -1：地雷，其他当前雷的数量
/// </summary>
public int Number { set; get; } = 0;
/// <summary>
/// 是否被Flag标识
/// </summary>
public bool IsFlag { get; set; } = false;
/// <summary>
/// 是否是雷
/// </summary>
public bool IsBoom => Number == -1;
}

主要代码已经实现，现已知现有代码的定时器由问题，暂时不支持Flag（旗子标识）。当然代码中还有其他不足的地方，游戏持续优化中。。。
