Close the main application from a different thread

Question

I am developing an application which is written by c# + HTML + Java Script in the following structure: the base window is a WPF MainWindow class that opens a thread which creates a web page. This thread handles all the UI events.

The WebBrowser XAML code is:

    <WebBrowser x:Name="CordovaBrowser" 
        Opacity="0"
        HorizontalAlignment="Stretch"  
        VerticalAlignment="Stretch" 
        Loaded="CordovaBrowser_Loaded" 
        Unloaded="CordovaBrowser_Unloaded"   
        LoadCompleted="CordovaBrowser_LoadCompleted" 
     />

The problem is that I want to close the application from the HTML thread. I cannot use App.Current.ShutDown() because I'm not in the main UI thread (I've tried to do so but got an exception).

(BTW: For who knows PhoneGap: my application structure is very similar to how the Win8 PhoneGap is built.)

Can anyone please help me? Thanks.

Answer 1

What you want is (edited and taken from Application.Current.Shutdown() doesn't )

ThreadStart ts = delegate()
{
    Dispatcher.BeginInvoke((Action)delegate()
    {
        Application.Current.Shutdown();
    });
 };
 Thread t = new Thread(ts);
 t.Start();
