I'm testing the program, I can’t write everywhere try... except . Is it possible to somehow display a message to the user like "Emergency shutdown of the program in case of emergency closing of the program, please remember your last actions"?

    If you want to catch all unhandled exceptions in your application, subscribe to AppDomain.UnhandledException

     [SecurityPermission(SecurityAction.Demand, Flags=SecurityPermissionFlag.ControlAppDomain)] public static void TestSomeException() { AppDomain domain = AppDomain.CurrentDomain; domain.UnhandledException += new UnhandledExceptionEventHandler(SomeExceptionHandler); throw new Exception("Тестовое исключение"); } static void SomeExceptionHandler(object sender, UnhandledExceptionEventArgs args) { Exception e = (Exception) args.ExceptionObject; // TODO: Обработать исключение } public static void Main() { TestSomeException(); }

      And can you be more specific for the inexperienced? Where to write [SecurityPermission(SecurityAction.Demand, Flags=SecurityPermissionFlag.ControlAppDomain)] ? And I probably will not handle the error, but simply close the application after the messagebox, but this.close does not work in static. classroom. Where can I write this? - Rakzin Roman
    • The attribute [i.e. the fact that in square brackets] should be attributed to the method that will establish the subscription to the event. About this.Close () - I suggest instead using, for example, Application.Exit (). - Maxim Kamalov
