windows 7中的捕获控制台退出C#

有人知道如何在windows中的c#控制台中对ctrl+c事件做出反应吗

这个问题：说明了如何做，但我已经尝试过了，它只在用户单击控制台窗口顶部的close X时捕获事件

当用户键入ctrl+c时不会发生任何事情，调试时它甚至不会命中处理程序

谢谢

这是我的密码

namespace EventCloseConsole
{
    using System.Runtime.InteropServices;
    using System;

    class Program
    {
        [DllImport("Kernel32")]
        private static extern bool SetConsoleCtrlHandler(EventHandler handler, bool add);

        private delegate bool EventHandler(CtrlType sig);
        static EventHandler _handler;

        enum CtrlType
        {
            CTRL_C_EVENT = 0,
            CTRL_BREAK_EVENT = 1,
            CTRL_CLOSE_EVENT = 2,
            CTRL_LOGOFF_EVENT = 5,
            CTRL_SHUTDOWN_EVENT = 6
        }

        private static bool Handler(CtrlType sig)
        {
            switch (sig)
            {
                case CtrlType.CTRL_C_EVENT:
                case CtrlType.CTRL_LOGOFF_EVENT:
                case CtrlType.CTRL_SHUTDOWN_EVENT:
                case CtrlType.CTRL_CLOSE_EVENT:

                    Console.WriteLine("Closing");
                    System.Threading.Thread.Sleep(500);
                    return false;
                default:
                    return true;
            }
        }

        static void Main(string[] args)
        {

            _handler += new EventHandler(Handler);
            SetConsoleCtrlHandler(_handler, true);
            Console.ReadLine();


        }
    }
}

您需要将Console.CancelKeyPress事件连接到处理程序。这是一篇关于这个主题的好文章

这在Windows 7上对我很有效。用x按钮关闭
秘密在于可变静态控制台eventdelegate\u d

private static void Main(string[] args)
{
    ConsoleEventHooker.Closed += ConsoleEventHooker_Closed;
}

static void ConsoleHooker_Closed(object sender, EventArgs e)
{
}

ConsoleEventHooker.cs

namespace System
{
    internal static class ConsoleEventHooker
    {
        private static bool _initedHooker;
        private static EventHandler _closed; 
        private static EventHandler _shutdown;
        private static ConsoleEventDelegate _d;

        public static event EventHandler Closed
        {
            add
            {
                Init();
                _closed += value;
            }
            remove { _closed -= value; }
        }

        public static event EventHandler Shutdown
        {
            add
            {
                Init();
                _shutdown += value;
            }
            remove { _shutdown -= value; }
        }

        private static void Init()
        {
            if (_initedHooker) return;
            _initedHooker = true;
            _d = ConsoleEventCallback;
            SetConsoleCtrlHandler(_d, true);
        }

        private static bool ConsoleEventCallback(CtrlTypes eventType)
        {
            if (eventType == CtrlTypes.CTRL_CLOSE_EVENT)
            {
                if(_closed != null) _closed(null,new EventArgs());
            }

            if (eventType == CtrlTypes.CTRL_SHUTDOWN_EVENT)
            {
                if (_shutdown != null) _shutdown(null, new EventArgs());
            }
            return false;
        }

        // A delegate type to be used as the handler routine 
        // for SetConsoleCtrlHandler.
        delegate bool ConsoleEventDelegate(CtrlTypes ctrlType);

        [DllImport("kernel32.dll", SetLastError = true)]
        private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);

    }

    // 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
    }

调试器遇到了阻碍，它也会查找Ctrl+C。用Ctrl+F5启动程序以测试这一点。不幸的是，这对我不起作用，我将代码直接复制并粘贴到一个新的控制台应用程序中。我注意到这是在2006年写的，可能是因为我使用的是Windows7吗？这应该是正确的。你能在你的问题中添加你尝试过的代码吗。只需添加Console.CancelKeyPress+=新的ConsoleCancelEventHandler（myHandler）；到主方法，该链接现在已断开。改为添加了msdn链接。
