在控制台应用程序中禁用用户输入

Disabling User Input in a Console Application(在控制台应用程序中禁用用户输入)

问题描述

我正在制作一个基于 C# 控制台文本的游戏，并且因为我希望它看起来更老派，所以我添加了一种效果，使任何文本(描述、教程、对话)看起来都像是正在输入的，并且它看起来像这样:

I am making a C# console text-based game, and because I wanted it to look more old-school, I've added an effect so that any text (descriptions, tutorials, dialogues) looks like it's being typed, and it looks like this:

public static int pauseTime = 50;

class Writer
{
    public void WriteLine(string myText)
    {
        int pauseTime = MainClass.time;
        for (int i = 0; i < myText.Length; i++)
        {
                Console.Write(myText[i]);
                System.Threading.Thread.Sleep(pauseTime);
        }
        Console.WriteLine("");
    }
}

但后来我觉得这可能很烦人，我想添加一个选项来跳过效果并让所有文本立即出现.所以我选择了 Enter 键作为跳过"键，它使文本立即出现，但按 Enter 键也会创建一个新的文本行，打乱文本.

But then I thought that this might be annoying and I thought about adding an option to skip the effect and make all the text appear at once. So I chose the Enter key to be the "skip" key, and it makes the text appear at once, but pressing the enter key also creates a new text line, scrambling the text.

所以我想以某种方式禁用用户输入，以便用户无法在控制台中写入任何内容.有没有办法，例如，禁用命令提示符(命令提示符不是指 cmd.exe，而是闪烁的_"下划线符号)?

So I want to somehow disable user input, so that the user cannot write anything in the console. Is there a way to, for example, disable the command prompt (and by command prompt I don't mean cmd.exe, but the flashing "_" underscore sign)?

推荐答案

我认为你想要的是 Console.ReadKey(true) 它将拦截按下的键并且不会显示它.

I think what you want is Console.ReadKey(true) which will intercept the pressed key and won't display it.

class Writer
{
    public void WriteLine(string myText)
    {
        for (int i = 0; i < myText.Length; i++)
        {
            if (Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Enter)
            {
                Console.Write(myText.Substring(i, myText.Length - i));
                break;
            }
            Console.Write(myText[i]);
            System.Threading.Thread.Sleep(pauseTime);
        }
        Console.WriteLine("");
    }
}
