简单的总结一下，如何利用C#进行WinForm 扫雷小游戏的开发： 扫雷游戏的主要设计的类有三个： Main、Pane 、MineField 1）Main 是主控窗体，负责项目的启动和关闭；并协调内部各个组建模块的协调工作。 2）Pane是一个方格的封装，是雷区的重要组建；它表示一个方格的当前状态，以及是否布雷等信息。 3）MineField是雷区的封装，是游戏的核心组建；它负责方格的布局以及地雷的分布；并控制玩家的基本操作以及正确的响应。 类的实现： 一、 Pane类 功能描述：Pane是一个方格的封装，是雷区的重要组建；它表示一个方格的当前状态，以及是否布雷等信息 One.它所具有的公共属性：
Two.它所具有的公共方法：
Three：源码： //默认的构造方法 public Pane() {InitializeComponent(); this.BackgroundImageLayout = ImageLayout.Stretch; } //公有属性： Public bool HasMine { get; set; } Public int AroundMineCount { get; set; } Public PaneState State { get; set; } //由于它有几种状态，设置一个枚举类型属性 public enum PaneState { Closed, //关闭状态 Opened, //打开状态 Marked, //标记状态 } //共有方法： public void Mark() //标记当前方格为又雷状态，插个小红旗 { this.BackgroundImage = Properties.Resources.Marked; this.State = PaneState.Marked; } public void Reset() //恢复标记状态，取消小红旗标记 { this.BackgroundImage = null; this.State = PaneState.Closed; } //打开方法 //打开后如果如果有雷,则显示地理图标;否则如果周围有相邻的地理，则显示地雷数量。 public void Open() { if (this.HasMine) { this.BackgroundImage = Properties.Resources.MineBomp; this.Enabled = false; } else { switch (this.AroundMineCount) { case 0: this.BackgroundImage = null; this.Enabled = false; break; case 1: this.BackgroundImage = Properties.Resources.Num1; this.Enabled = false; break; case 2: this.BackgroundImage = Properties.Resources.Num2; this.Enabled = false; break; case 3: this.BackgroundImage = Properties.Resources.Num3; this.Enabled = false; break; case 4: this.BackgroundImage = Properties.Resources.Num4; this.Enabled = false; break; case 5: this.BackgroundImage = Properties.Resources.Num5; this.Enabled = false; break; case 6: this.BackgroundImage = Properties.Resources.Num6; this.Enabled = false; break; case 7: this.BackgroundImage = Properties.Resources.Num7; this.Enabled = false; break; case 8: this.BackgroundImage = Properties.Resources.Num8; this.Enabled = false; break; } } } 二、 MineField类 功能描述：CrlMineField是雷区的封装，是游戏的核心组建；它负责方格的布局以及地雷的分布；并控制玩家的基本操作以及正确的响应。 One.它所具有的公有方法
Two.它有具有的私有方法
Three.事件处理
Four.源码 //事件的委托 public delegate void MineSweepingCompletedEventHandler(object sender, EventArgs e); public delegate void MineSweepingFailedEventHandler(object sender, EventArgs e); public partial class CrlMineField : UserControl { //成功和失败两个委托事件的申明 public event MineSweepingCompletedEventHandler MineSweepingCompleted; public event MineSweepingFailedEventHandler MineSweepingFailed; public CrlMineField() { InitializeComponent(); }
/// <summary> /// 初始化雷区 /// </summary> /// <param name="paneNumber">每排方块的数量</param> /// <param name="mineNumber">地雷的数量</param> public void InitMineField(int paneNumber, int mineNumber) { if (mineNumber >= paneNumber * paneNumber) { throw new ApplicationException("地雷太多了，不合法游戏规则。"); } // 清空现有的所有方块 if (this.Controls.Count > 0) { this.Controls.Clear(); } //添加雷区方格 for (int i = 0; i < paneNumber * paneNumber; i++) { Pane pane = new Pane(); pane.MouseDown += new MouseEventHandler(OnPaneMouseDown); this.Controls.Add(pane); }
// 布局方格 this.LayoutPanes(); // 随机部署地雷 this.LayMines(mineNumber); // 设置每个方格周边的地雷数 foreach (Pane p in this.Controls) { p.AroundMineCount = this.GetMineCountAround(p); } } /// <summary> /// 明示雷区的全部方块里的内容 /// </summary> public void DisplayAll() { foreach (Pane pane in this.Controls) { if (pane.State != PaneState.Opened) { pane.Open(); } } } /// <summary> /// 明示与给定方格相关联的无地雷的方格 /// </summary> /// <param name="pane"></param> public void DisplayAround(Pane pane) { if (pane.State == PaneState.Opened || pane.HasMine) { return; } // 明示当前方格本身 pane.Open(); // 通过递归明示当前方格四周的所有方格 List<Pane> panesAround = this.GetPanesAround(pane); foreach (Pane p in panesAround) { // 如果该方格四周没有相邻的地雷，则递归 if (this.GetMineCountAround(p) == 0) { this.DisplayAround(p); } else { if (p.State != PaneState.Opened && !p.HasMine) { p.Open(); }
