中断到Console.ReadLine [英] Interrupt Console.ReadLine

问题描述

是否可以停止到Console.ReadLine（）编程？

我有一个控制台应用程序的大部分逻辑在不同的线程运行，并在主线程我接受输入使用到Console.ReadLine（）。我想停止从控制台读取时分离出的线程停止运行。

I have a console application: the much of the logic runs on a different thread and in the main thread I accept input using Console.ReadLine(). I'd like to stop reading from console when the separated thread stop running.

我怎样才能做到这一点？

How can I achieve this?

推荐答案

这是可能的，你必须关闭标准输入流挺举的地板垫。此程序演示的想法：

It's possible, you have to jerk the floor mat by closing the stdin stream. This program demonstrates the idea:

using System;
using System.Threading;
using System.Runtime.InteropServices;

namespace ConsoleApplication2 {
    class Program {
        static void Main(string[] args) {
            ThreadPool.QueueUserWorkItem((o) => {
                Thread.Sleep(1000);
                IntPtr stdin = GetStdHandle(StdHandle.Stdin);
                CloseHandle(stdin);
            });
            Console.ReadLine();
        }

        // P/Invoke:
        private enum StdHandle { Stdin = -10, Stdout = -11, Stderr = -12 };
        [DllImport("kernel32.dll")]
        private static extern IntPtr GetStdHandle(StdHandle std);
        [DllImport("kernel32.dll")]
        private static extern bool CloseHandle(IntPtr hdl);
    }
}
