试图了解 C# Winforms 中的计时器和虚拟点击。我想让程序有一个用户输入的时间值(textbox1),然后等待这段时间并单击鼠标,然后增加数字计数器(textbox2)。
在下面的代码中,数字计数器立即变为 10,但点击永远不会结束,尽管设置了一个 while 循环以在 10 处停止点击。我基本上只是希望程序等待一个稍微随机的时间(时间输入到时间输入 +3),单击鼠标,增加计数器,然后选择一个新的随机数并继续,直到总共点击 10 次。
public Form1()
{
InitializeComponent();
}

char ch = e.KeyChar;
if (!Char.IsDigit(ch) && ch != 8)
{
e.Handled = true;
}
