C#—打字游戏

/*
     * 利用Random类，结合Timer控件，设计窗体。在窗体上的文本框中显示一个大写字符，如果用户输入正确，则产生另一个大写字符。
     * 实现打字游戏。（提示：金山打字通的简易版）窗体中的按钮可以用菜单实现。
     * 菜单命令组成：
     * （1）“设置”菜单：开始游戏、结束游戏和退出游戏。
     * （2）“查看”菜单：查看正确率和打字所用的时间。
     * 提示与思考：
     * （1）判断输入字符正确与否，采用哪个控件的哪个事件；
     * （2）首先考虑如何实现一个静止的字符（不移动）的输入判断；然后考虑如何让字符动起来；
     * （3）如果字符移出窗体边界，仍然没有输入正确，如何让该字符重新出现在窗体的顶端某处。
