Changing Ribbon Tab Name Throws Exception

Question

I tried to change the Tab Name like this:

foreach (Window window in Application.Current.Windows)
{
  (window as MainWindow).HomeTab.Header = "Teaching Learning Based Optimization";
}

However all I get is an NullReferenceException. What am I missing?

P.S. Solved it! Did this:

if (window.GetType() == typeof(MainWindow))
{
  //Code
}

Thanks for the suggestions though.

Don't use `GetType()` for the overhead. Use `is` instead. This will also fail when `window` is `null`. – Patrick Hofman Jul 28 '14 at 09:28
