检测时，控制台应用程序正在关闭/杀？ [英] Detect when console application is closing/killed?

问题描述

我想作一个安全出口的，这将在Linux上使用单声道运行我的控制台应用程序，但我不能找到一个解决方案来检测阉信号发送给它或用户按下Ctrl + C。

I wanted to make a safe exit for my console application that will be running on linux using mono but I can't find a solution to detect wether a signal was sent to it or the user pressed ctrl+c.

在Windows，有一个核函数SetConsoleCtrlHandler该做这项工作，但是，单是行不通的。

On windows there is the kernel function SetConsoleCtrlHandler which does the job but that doesnt work on mono.

我如何获得在我的控制台应用程序安全出口它closing事件？

How do I get a closing event on my console application to safe exit it ?

推荐答案

您需要使用 Mono.UnixSignal ，还有张贴乔纳森·普赖尔一个很好的例子： HTTP ：//www.jprl.com/Blog/archive/development/mono/2008/Feb-08.html

You need to use Mono.UnixSignal, there's a good sample posted by Jonathan Pryor : http://www.jprl.com/Blog/archive/development/mono/2008/Feb-08.html

还有在Mono较短的例子页面： FAQ /技术/操作系统问题/信号处理：

There's also a shorter example on Mono page: FAQ / Technical / Operating System Questions / Signal Handling:

// Catch SIGINT and SIGUSR1
UnixSignal[] signals = new UnixSignal [] {
    new UnixSignal (Mono.Unix.Native.Signum.SIGINT),
    new UnixSignal (Mono.Unix.Native.Signum.SIGUSR1),
};

Thread signal_thread = new Thread (delegate () {
    while (true) {
        // Wait for a signal to be delivered
        int index = UnixSignal.WaitAny (signals, -1);

        Mono.Unix.Native.Signum signal = signals [index].Signum;

        // Notify the main thread that a signal was received,
        // you can use things like:
        //    Application.Invoke () for Gtk#
        //    Control.Invoke on Windows.Forms
        //    Write to a pipe created with UnixPipes for server apps.
        //    Use an AutoResetEvent

        // For example, this works with Gtk#    
        Application.Invoke (delegate () { ReceivedSignal (signal); });
    }});
