Catching Unhandled Exceptions [C#]

This example shows how to manage all exceptions that haven't been caught in the try-catch sections (in Windows Forms application).

The UnhandledException event handles uncaught exceptions thrown from the main UI thread. The ThreadException event handles uncaught exceptions thrown from non-UI threads.

[C#]

static void Main()
{
  Application.EnableVisualStyles();
  Application.SetCompatibleTextRenderingDefault(false);

  Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException);
  AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

  Application.Run(new Form1());
}

static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
{
  MessageBox.Show(e.Exception.Message, "Unhandled Thread Exception");
  // here you can log the exception ...
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
  MessageBox.Show((e.ExceptionObject as Exception).Message, "Unhandled UI Exception");
  // here you can log the exception ...
}
