C#: How do you display the modifier key name + non-modifier key name in this keydown event?

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,          


        

Answer 1

You need to display the right string depending on the bool value. To do things like that in a single statement, use the ? : operator:

txtShortcut.Text = (e.Shift ? "[Shift]" : string.Empty) + 
                   (e.Control ? "[Ctrl]" : string.Empty) + ...;

Generally, it's:

 ?  : 

It works with any type.
