掃雷游戲，大家都應該玩過吧！其實規則也很簡單，可是我們想自己實現一個掃雷，我們應該怎么做呢？
Step1: 知曉游戲原理
掃雷就是要把所有非地雷的格子揭開即勝利；踩到地雷格子就算失敗。游戲主區域由很多個方格組成。使用鼠標左鍵隨機點擊一個方格，方格即被打開并顯示出方格中的數字；方格中數字則表示其周圍的8個方格隱藏了幾顆雷；如果點開的格子為空白格，即其周圍有0顆雷，則其周圍格子自動打開；如果其周圍還有空白格，則會引發連鎖反應；在你認為有雷的格子上，點擊右鍵即可標記雷；如果一個已打開格子周圍所有的雷已經正確標出，則可以在此格上同時點擊鼠標左右鍵以打開其周圍剩余的無雷格。
1代表1的上下左右及斜角合計有一顆雷，依次輪推，2則有2顆，3則有3顆..
在確實是炸彈的方格上點了旗子，就安全了，不是炸彈的被點了旗子，后面會被炸死的..問號就先不確定這里有沒有炸彈，不會存在點錯了被炸死的狀況..
Step2: 由step1可知，游戲由格子組成，翻譯成代碼語言就叫做數組，也就是游戲地圖就是一個二維數組。格子對象，格子的值即當前雷的數量，那么此時我們暫定雷的數字標識為-1。除此之外，格子對象還有是否被顯示，顯示當前雷數量等屬性，那么我們大概可以定義這樣一個類：
public class CellBlockRole { /// <summary> /// 位于游戲地圖中的坐標點X /// </summary> public int X { get; set; } /// <summary> /// 位于游戲地圖中的坐標點Y /// </summary> public int Y { get; set; } /// <summary> /// 是否展示最后格子所代表的結果 /// </summary> public bool IsShowResult { get; set; } = false; /// <summary> /// 是否計算數字結果 /// </summary> public bool IsComputeResult { get; set; } = false; /// <summary> /// 是否已經展示過計算結果了 /// </summary> public bool IsHasShowComputed { get; set; } = false; /// <summary> /// 當前的格子的角色數字， -1：地雷，其他當前雷的數量 /// </summary> public int Number { set; get; } = 0; /// <summary> /// 是否被Flag標識 /// </summary> public bool IsFlag { get; set; } = false; /// <summary> /// 是否是雷 /// </summary> public bool IsBoom => Number == -1; }繪制游戲UI畫面，見代碼：
