C＃-控制台按键 [英] C# - Console Keystrokes

问题描述

如果它们相等，我想将控制台中的按键与左箭头键进行比较，这意味着按下的键是左箭头键，该键将控制台的背景色更改为青色...

I want to compare the key pressed in a console to the left arrow key if they are equal meaning the key pressed was the left arrow key, key change the background color of the console to cyan...

我不确定如何设置If语句，因为我不知道如何比较控制台中的键。

I'm not sure how to set up the If statement though, because I dont know how to compare keys in a console.

using System;

namespace ConsolePaint
{
class MainClass
{


    public static void Main (string[] args)
    {
        ConsoleKeyInfo keypress;
        keypress = Console.ReadKey(); // read keystrokes 

        if ( keypress.KeyChar == ConsoleKey.LeftArrow )
        {
            Console.BackgroundColor = "Cyan";
        }
    }
}

}

推荐答案

尝试一下：

ConsoleKeyInfo keypress;
keypress = Console.ReadKey(); // read keystrokes 

if (keypress.Key == ConsoleKey.LeftArrow)
{
    Console.BackgroundColor = ConsoleColor.Cyan;
}
