如何处理控制台应用程序键preSS事件 [英] how to handle key press event in console application

问题描述

我想创建一个控制台应用程序，将显示一个pssed控制台屏幕上$ P $关键，我做了这个code迄今：

I want to create a console application that will display the key that is pressed on console screen, I made this code so far:

    static void Main(string[] args)
    {
        // this is absolutely wrong, but I hope you get what I mean
        PreviewKeyDownEventArgs += new PreviewKeyDownEventArgs(keylogger);
    }

    private void keylogger(KeyEventArgs e)
    {
        Console.Write(e.KeyCode);
    }

我想知道，我应该在主要类型，以便我可以调用该事件？

I want to know, what should I type in main so I can call that event?

推荐答案

有关控制台应用程序，你可以做到这一点，做的，而循环运行，直到你preSS X

For console application you can do this, the do while loop runs untill you press x

public class Program
{
    public static void Main()
    {

        ConsoleKeyInfo keyinfo;
        do
        {
            keyinfo = Console.ReadKey();
            Console.WriteLine(keyinfo.Key + " was pressed");
        }
        while (keyinfo.Key != ConsoleKey.X);
    }
}

这如果你的控制台应用程序具有焦点只会工作。如果您要收集全系统的关键preSS事件，你可以使用 windows钩子

This will only work if your console application has focus. If you want to gather system wide key press events you can use windows hooks
