我怎样才能保持一个控制台打开，直到CancelKey preSS事件被解雇？ [英] How can I keep a console open until CancelKeyPress event is fired?

问题描述

什么是保持一个控制台应用程序，只要CancelKey preSS事件还没有被解雇开的最好方式？

What is the best way to keep a console application open as long as the CancelKeyPress event has not been fired?

我会preFER不使用Console.Read或到Console.ReadLine，因为我不想接受输入。我只想让底层应用程序打印到控制台事件的详细信息，因为他们被解雇。那么一旦CancelKey preSS事件触发我想平稳地关闭应用程序。

I would prefer to not use Console.Read or Console.ReadLine as I do not want to accept input. I just want to enable the underlying application to print to the console event details as they are fired. Then once the CancelKeyPress event is fired I want to gracefully shut down the application.

推荐答案

我假设正常关闭的应用程序是你在挣扎这里的一部分。否则，你的应用程序会自动退出的CTRL-C。您应该更改标题。

I'm assuming that "gracefully shut down the application" is the part you are struggling with here. Otherwise your application will automatically exit on ctrl-c. You should change the title.

下面是什么，我想你需要一个快速演示。它可以改进多一点与使用锁定和监控的通知。我不知道正是你需要的，所以我就提出这个...

Here's a quick demo of what I think you need. It could be refined a bit more with use of locking and Monitors for notification. I'm not sure exactly what you need though, so I'll just pose this...

class Program
{

    private static bool _s_stop = false;

    public static void Main(string[] args)
    {
        Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);
        while (!_s_stop)
        {
            /* put real logic here */
            Console.WriteLine("still running at {0}", DateTime.Now);
            Thread.Sleep(3000);
        }
        Console.WriteLine("Graceful shut down code here...");

        //don't leave this...  demonstration purposes only...
        Console.ReadLine();
    }

    static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
    {
        //you have 2 options here, leave e.Cancel set to false and just handle any
        //graceful shutdown that you can while in here, or set a flag to notify the other
        //thread at the next check that it's to shut down.  I'll do the 2nd option
        e.Cancel = true;
        _s_stop = true;
        Console.WriteLine("CancelKeyPress fired...");
    }

}
