C# 控制台应用程序：防止打印 Control-C？

发布于 2024-09-05 19:32:13 字数 410 浏览 10 评论 0原文

我有一个控制台应用程序，我想捕获 Control-C 并正常关闭。

我有以下代码：

Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) =>
{
   Logger.Log("Control+C hit. Shutting down.");
   resetEvent.Set();
});

输出窗口显示：

6/16/2010 3:24:34 PM：按 Control+C。正在关闭。
^C

有没有办法防止 control-c 字符 ^C 出现？这不是什么大事，但出于某种原因我会很关注它，因为我就是这样的肛门。

I have a console app, and I want to capture Control-C and shutdown gracefully.

I have the following code:

Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) =>
{
   Logger.Log("Control+C hit. Shutting down.");
   resetEvent.Set();
});

And the output windows shows:

6/16/2010 3:24:34 PM: Control+C hit. Shutting down.
^C

Is there a way to prevent the control-c character ^C from appearing? It's not a huge deal, but for some reason Ill be fixated on it because I'm anal like that.

作为控制台应用程序，我将使用 Environment.Exit 来表示应用程序正在退出，这样可以阻止 ^C 被打印。

您甚至可以提供特定的错误代码来表示用户按下了 CTRL+C。

static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
    Console.WriteLine("Control+C hit. Shutting down."); 

    Environment.Exit(-1);
}

Being a console application I would use Environment.Exit to signal that the application is exiting and this way stopping the ^C from being print.

You could even provide a specific error code to symbolize that the user pressed CTRL+C.

static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
    Console.WriteLine("Control+C hit. Shutting down."); 

    Environment.Exit(-1);
}

这应该有效...

Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) =>
{
    Console.WriteLine("Control+C hit. Shutting down.");
    Environment.Exit(0);
});

Console.ReadLine();

This should work...

Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) =>
{
    Console.WriteLine("Control+C hit. Shutting down.");
    Environment.Exit(0);
});

Console.ReadLine();

虽然这不一定是您想要实现的解决方案，但它确实会阻止显示 ^C：

static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
    Console.WriteLine("Control+C hit. Shutting down.");     
    Process.GetCurrentProcess().Kill();
}

While this is not necessarily a solution you want to implement, it does prevent the ^C from being displayed:

static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
    Console.WriteLine("Control+C hit. Shutting down.");     
    Process.GetCurrentProcess().Kill();
}
