Question

在线编辑迷你吃豆子游戏的教程。我仍然需要修复一些错误，但无法获取用户输入。我希望在游戏结束后用户按下“ r”键时重新启动。

我曾尝试接受用户输入，但是经常崩溃。因此，我在比赛结束或获胜后自行重新启动。随着游戏结束，它开始一个新窗口。如果我赢了，它会产生多个窗口。我知道这是因为我的foreach循环。

Id希望在游戏结束后一直坐在那里，直到我按下r或关闭窗户它会自动重新启动，从而产生一个新的屏幕。理想情况下，id只是重新启动游戏。同样，我希望能够根据用户输入而不是在游戏结束后使用它。如果您赢了，它会产生许多新窗口，因为每个窗口都是理想的，但是再次理想地，id只是希望用户输入“ r”

您可以生成一个新的消息框，然后等待它们单击确定。

DialogResult d = MessageBox.Show("Do you wanna Retry?", "delete", MessageBoxButtons.YesNo);
            if (d == DialogResult.Yes)
            {
               //do something
            }

停止计时器后读取用户输入？
