如何在.NET 4中使用Console.CancelKeyPress？ （在.NET 3.5及更低版本中工作良好） [英] How do I use Console.CancelKeyPress in .NET 4? (Works fine in .NET 3.5 and below)

问题描述

我在C＃4中写了一个控制台应用程序，希望正常取消我的程序，按Ctrl + C。下面的代码我已经使用了很多次，但现在当试图在.NET 4中使用它，似乎一个奇怪的未处理的异常发生。

I am writing a Console app in C# 4 and want to gracefully cancel my program and Ctrl + C is pressed. The following code I have used many times before, but now when trying to use it in .NET 4, it seems a strange unhandled exception is occurring.

namespace ConsoleTest
{
    class Program
    {
        private static bool stop = false;

        static void Main(string[] args)
        {
            System.Console.TreatControlCAsInput = false;
            System.Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);

            while (!stop)
            {
                System.Console.WriteLine("waiting...");
                System.Threading.Thread.Sleep(1000);
            }
            System.Console.WriteLine("Press any key to exit...");
            System.Console.ReadKey(true);
        }

        static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
        {
            stop = true;
            e.Cancel = true;
        }
    }
}

目标框架到.NET 3.5，它工作。

推荐答案

这是 Microsoft Connect 。

请注意，它在调试器之外工作。

Note that it does work outside of the debugger.
