Brothers In Code

I'm currently converting a winforms app into a WPF app and discovered the key events are significantly different in WPF.  Here's a few tips and things to look out for:

• The old KeyPressEventArgs.KeyChar is just a char and included the modifier key stroke (CTRL-S = 'S'-64 = (Char)19, SHIFT-S = 's'-32 = 'S').
• The new KeyEventArgs.Key is an enum that includes every key.  Modifier keys are their own key stroke.
• (Char)KeyInterop.VirtualKeyFromKey(e.Key) will get you the char value from the new enum, although it is always upper case. 
• Since modifier keys raise an event in WPF, I find I'm ignoring them alot:
  

  
  //ignore modifier keys
  if (e.Key == Key.LeftCtrl ||
          e.Key == Key.RightCtrl ||
          e.Key == Key.LeftAlt ||
          e.Key == Key.RightAlt ||
          e.Key == Key.LeftShift ||
          e.Key == Key.RightShift)
  {
    e.Handled = false;
    return;
  }
