Terminate application after unhandled exception

Question

I have a problem in a WPF application. I wrote this code:

public partial class App : Application
{
    public App()
    {
        AppDomain.CurrentDoma         


        

Answer 1

You can also use Application.Exit() or System.Environment.Exit(exitCode) to immediately shut down your application after you have shown your error dialog box.

Answer 2

You can avoid multiple messageboxes by initializing a static boolean firstTime to true and use the code within the Exception handler:

void MyHandler(object sender, UnhandledExceptionEventArgs e) 
{ 
   if (firstTime){
        Exception exception = e.ExceptionObject as Exception; 
        MessageBox.Show(exception.Message, "ERROR", 
                        MessageBoxButton.OK, MessageBoxImage.Error); 
        firstTime = false;
   }else{
        // Now kill the process....
   }
} 

To terminate the process do this, within the MyHandler:

System.Diagnostics.Process proc = System.Diagnostics.Process.GetCurrentProcess();
proc.Kill();
