如何删除控制台应用程序中显示的文本，c#？

Question

假设用户被要求提供手册。现在我们都知道手册既方便又广泛，例如我如何折叠/清除以便用户可以继续下一个活动？通过在按 M 后按 C，我希望用户立即跳转到下一个活动。

如何删除它？

这是代码：

static void Main(string[] args)
        {
            Console.WriteLine("Do you want to play the game?\nPress Y to continue\tPress M to view the rules\tEnter any key to exit. ");

            string iQuestion = Console.ReadLine();
            if (iQuestion.Equals("y", StringComparison.OrdinalIgnoreCase))
            {
                ProjectExecution();
                Console.WriteLine("\nWorld you like to try again?\nPress y to play again\tEnter any key to exit. ");
                string ask = Console.ReadLine();
                if (ask.Equals("y", StringComparison.OrdinalIgnoreCase))
                {
                    ProjectExecution();
                }
                else
                {
                    Console.WriteLine("Thank you for playing");
                }
                Console.Read();
            }
            else if (iQuestion.Equals("m", StringComparison.OrdinalIgnoreCase))
            {
                Console.WriteLine("Hwewewe\nPress C to continue");\\This is just an example
                string mQuestion = Console.ReadLine();
                if (mQuestion.Equals("c", StringComparison.OrdinalIgnoreCase))
                {
                    Console.Clear();
                    ProjectExecution();
                    Console.Read();
                }
            }
            else
            {
                Environment.Exit(10);
            }
        }

我愿意接受另一种解决方案。

我正在寻找相同的答案。我希望能够按 A 打开控制台行，但我不希望用户的文本出现在控制台中。

这是我的代码：

Console.BackgroundColor = ConsoleColor.Black;
static void PrintNewLine(int n)
{
    string newLines = new String('\n', n - 1);
    Console.WriteLine(newLines);
}
        Console.ForegroundColor = ConsoleColor.Cyan;
        Console.WriteLine("TCO Blossom Acquisition Script");

        PrintNewLine(1);
        Console.ForegroundColor = ConsoleColor.White;
        Console.WriteLine("Hello, Mr/Mrs/Ms _____?  My name is _____ and I’m calling on behalf of the Cleveland \r\nOrchestra. First and foremost I wanted to thank you for attending the Blossom Festival, \r\nI see you joined us for the (last concert in history) concert - I’d love to know how you \r\nenjoyed that performance! ");
        PrintNewLine(1);

        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("(Build rapport with open ended questions - what was the highlight of the evening? How did they like their seats? etc)");
        PrintNewLine(1);
        Console.ForegroundColor = ConsoleColor.White;
        Console.WriteLine("Thank you for that, we always appreciate hearing from our audience members!  We’re \r\nexcited to have another great summer of music lined up this year - from classical \r\nfavorites like Rhapsody in Blue, to great films like Indiana Jones and Lord of the Rings, \r\nto special guest artists like Leslie Odom Jr of “Hamilton” fame, it’s going to be a great \r\nseason!

        Console.ForegroundColor = ConsoleColor.Yellow;
        Console.WriteLine("*Let me ask you this, do you prefer symphonic masterworks, or music from film, Broadway and popular entertainers?*");
