问是否可以从webbrowser NavigationFailed事件中导航？

EN

private void webBrowser_NavigationFailed(object sender, NavigationFailedEventArgs e)
    {
        Debug.WriteLine("Navigation Failed");

        if (!Utils.IsNetworkAvailable())
        {
            MessageBoxResult result = MessageBox.Show("Please go to Settings and enable your network connection.",
                                                 "No network connection", MessageBoxButton.OK);

            if (result == MessageBoxResult.OK)
            {                    
                Dispatcher.BeginInvoke(() => 
                    NavigationService.Navigate(new Uri("/TutorialPage.xaml", UriKind.Relative))); //TODO: Doesnt work
            }
        }
}
