在控制台关闭运行代码？

Question

我正在编写一个C#应用程序,需要在控制台关闭时上传文件(通过X按钮,或者计算机关闭).

我怎么能这样做？

AppDomain.CurrentDomain.ProcessExit += new EventHandler (OnExit);

仅在我exit向控制台发出命令时运行,而不是在我按下红色关闭按钮时运行.

请仅在解决方案通过X按钮关闭控制台时运行解决方案,并且当计算机关闭时(通常通过Windows,我知道如果电源被拉到xD则不能).

您必须调用WIN32 API,为此,请在这里查看这篇文章 http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/707e9ae1-a53f-4918-8ac4- 62a1eddb3c4a /

我从那里复制了相关的代码:

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_CLOSE_EVENT:
                isclosing = true;
                Console.WriteLine("Program being closed!");
                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.

    public enum CtrlTypes
    {
        CTRL_C_EVENT = 0,
        CTRL_BREAK_EVENT,
        CTRL_CLOSE_EVENT,
        CTRL_LOGOFF_EVENT = 5,
        CTRL_SHUTDOWN_EVENT
    }

    #endregion
}

它完全符合您的需求.

问候,
