扫雷-c#

一、实验目的：

1、掌握c#窗体和控件的常用属性和功能
2、完成扫雷游戏的基本功能

二、实验要求：

1、游戏基本功能必须实现。鼠标左键点非雷点，否则游戏结束；鼠标右键一次标记雷点，邮件两次标记上问号，右键三次取消标记。
2、可以对游戏选择难度，分为初级、中级和高级，按笑脸按钮重新开始游戏
3、符合游戏逻辑。每个点周围的雷的个数必须正确
4、点开雷点，显示游戏结束，并且显示各个点的情况
5、点开所有非雷点或者标记完所有雷点时，能够显示游戏胜利
6、不接受键盘操作，只接受鼠标操作

三、实验内容：

1、构建菜单栏，添加开始栏、帮助栏，开始栏用于游戏难度的选择，帮助栏用于游戏规则的介绍
2、创建雷区，使用buttonarray模拟雷区，start按钮用于重新开始游戏
3、鼠标左键时，分三种情况：
	（1）鼠标点击雷点时，直接显示游戏结束
	（2）鼠标点击空白点时，周围没雷，则显示周围点的情况，周围有雷，只显示此点的雷数
	（3）鼠标左键点了一个大于0的数字，显示周围雷点的情况，若周围雷点标错，直接显示游戏结束
4、鼠标右键时，第一次标记为雷点，第二次标记为疑问，第三次取消标记。
5、显示周围点的情况时，因为周围点的雷点数也可能为0，还需要显示此点周围的情况，需用递归，完成此项功能。
6、点击笑脸按钮时，如果不是第一次开始，就删除原有按钮，否则直接初始化长度、宽度和雷数，重新构建button按钮
7、点击菜单栏的难度选择按钮时，如果不是第一次开始，就删除原有按钮，否则直接初始化长度、宽度和雷数，重新构建button按钮

五、实验结果：
1、用”×”标记雷点，用”?”标记疑问点，空白点表示周围无雷点或者该点还未点开，根据颜色区别二者。
2、游戏胜利和游戏结束显示messagebox。
3、第一次开始点击笑脸按钮，重新开始点击哭脸按钮。
4、点击开始菜单栏的子菜单栏选择游戏难度，初级、中级、高级的雷点分别为10、40、99个
（初级）
（中级）
（高级）
点击雷点，显示游戏错误，游戏结束

六、总结
通过本次实验，对c#控件和窗体有了更深入的了解，懂得如何根据各个控件的特点实现扫雷对应的功能，希望在以后能更加熟练地使用各个控件。
