推荐答案

使用KeyDown和KeyUp代替KeyPress或P/Invoke GetKeyboardState.

您应该启用 KeyPreview [链接 [

Use KeyDown and KeyUp instead of KeyPress, or P/Invoke GetKeyboardState.

You should enable the KeyPreview[^] property. This link[^] will explain you the basics.

A tiny sample code will be like:

private void ctrl_KeyDown(object sender, KeyEventArgs e)
{
   if (e.Control && e.KeyCode == Keys.C)
   {
     // Do stuff when  Ctrl+C pressed
   }
}
