Question

I am using this code to detect whether modifier keys are being held down in the KeyDown event of a text box.

    private void txtShortcut_KeyDown(object sender, KeyEventArgs e)     {         if (e.Shift || e.Control || e.Alt)         {             txtShortcut.Text = (e.Shift.ToString() + e.Control.ToString() + e.Alt.ToString() + e.KeyCode.ToString());          }     } 

How would I display the actual modifier key name and not the bool result and also display the non-modifier key being pressed at the end of the modifier key if a non-modifier key like the letter A is being pressed at the same time too? Is there a way to do it all in the same txtShortcut.Text = (); line?

You can check the Control.ModifierKeys – because that is an enum it should be more human friendly. Alternatively, just

string s = (e.Shift ? '[Shift]+' : '') + (e.Control ? '[Ctrl]+' : '')            + (e.Alt ? '[Alt]+' : '') + e.KeyCode;
