推荐答案
如果您尝试在Windows Forms应用程序中执行此操作,则可以将这些代码添加到Form的KeyDown事件中(或者您需要使用哪个键事件) ):
If you are trying to do this in a windows forms application, maybe you can add these codes into the Form's KeyDown event(or which key event you need to use):
switch (e.KeyData)
{
//Detects that you pressed the Up Arrow Key, which key do you need, just
//write it here.
case Keys.Up:
//enter code here`
break;
}
