听键盘快捷键（c＃）

Question

How can i run a method when someone used a keyboard shortcut like Ctrl + G ?

The application is a Windows forms application and i only want to capture it when the form is activated.

Answer 1

Keyboard shortcuts are often referred to as "command keys". If you want first-crack at keypresses (before your child controls), the best place is to override the ProcessCmdKey method on your form.

Answer 2

Look at your OnKeyPress method on the Form or the KeyPress event for the Form.

Override the OnKeyPress like this...

protected override void OnKeyPress(KeyPressEventArgs e) { ... }

... and look at the KeyPressEventArgs to see what key was pressed and whether it was pressed with Ctrl.
