Graceful shutdown of console apps in Win Vista, 7, 2008

How do I handle th开发者_如何学编程e close/x button in console apps when running in Windows Vista, 7, 2008?

I found that I can capture the event by using SetConsoleControlHandler but Windows force terminates the app after a second (or milliseconds). That second isn't enough for my app to clean up.

If you detach the console in response, does it still close you down?

You can find out how to detect the application wants to close:

namespace Detect_Console_Application_Exit2
{
    class Program
    {
        private static bool isclosing = false;
        static void Main(string[] args)
        {
            SetConsoleCtrlHandler(new HandlerRoutine(ConsoleCtrlCheck), true);

            Console.WriteLine("CTRL+C,CTRL+BREAK or suppress the application to exit");
            while (!isclosing) ;

        }

        private static bool ConsoleCtrlCheck(CtrlTypes ctrlType)
        {
            // Put your own handler here
            switch (ctrlType)
            {
                case CtrlTypes.CTRL_C_EVENT:
                    isclosing = true;
                    Console.WriteLine("CTRL+C received!");
                    break;

                case CtrlTypes.CTRL_BREAK_EVENT:
                    isclosing = true;
                    Console.WriteLine("CTRL+BREAK received!");
                    break;

                case CtrlTypes.CTRL_CLOSE_EVENT:
                    isclosing = true;
                    Console.WriteLine("Program being closed!");
                    break;

                case CtrlTypes.CTRL_LOGOFF_EVENT:
                case CtrlTypes.CTRL_SHUTDOWN_EVENT:
                    isclosing = true;
                    Console.WriteLine("User is logging off!");
                    break;

            }
            return true;
        }



        #region unmanaged
        // Declare the SetConsoleCtrlHandler function
        // as external and receiving a delegate.

        [DllImport("Kernel32")]
        public static extern bool SetConsoleCtrlHandler(HandlerRoutine Handler, bool Add);

        // A delegate type to be used as the handler routine
        // for SetConsoleCtrlHandler.
        public delegate bool HandlerRoutine(CtrlTypes CtrlType);

        // An enumerated type for the control messages
        // sent to the handler routine.

As a last resort you can use Console.ReadLine() to stop the app from closing...

You can then do your clean up and exit the application.

Console.ReadLine()

//your clean up code here

//Exit
System.Windows.Forms.Application.Exit(0)
