Key down在c＃win的某些情况下不起作用。形成 [英] Key Down Not working in some cases in c# win. form

问题描述

我已经在这样的KeyDown事件上编写了代码

i have written a code on KeyDown event like this

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
     if (e.Alt == true && e.KeyData == Keys.V)
     {
          label4_Click(sender, e);
     }
     else if (e.Alt == true && e.KeyData == Keys.U)
     {
          label5_Click(sender, e);
     }
}

我想知道当我选择 Alt& V或U在一起为什么代码没有执行？



注意：KeyPreview = true（表格的属性）









提前致谢

I would like to know when i select Alt & V or U together why is the code not executing?

Note:KeyPreview=true (Form's Property)




Thanks in advance

推荐答案

您需要使用 KeyEventArgs.KeyCode Property [ ^ ]

you need to use KeyEventArgs.KeyCode Property[^]

if(e.KeyCode == Keys.V && e.Alt )
{
  label4_Click(sender, e);
}
if(e.KeyCode == Keys.U && e.Alt )
{
  label5_Click(sender, e);
}
