如何在控制台应用程序中处理按键事件 [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，它将显示在控制台屏幕上按下的键，我将此代码提交到目前为止：

I want to create a console application that will display the key that is pressed on the 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，我应该输入主要内容，所以我可以称之为事件？

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

推荐答案

对于控制台应用程序，您可以执行此操作， do while 循环运行，直到你按 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);
    }
}

只有在您的控制台应用程序有焦点。如果您想收集系统范围的按键新闻事件，可以使用 windows hooks

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
