在 C# 中使用 enter 键绕过多个 foreach 循环

Question

我目前正在 C# 控制台中制作一个文本冒险游戏，它会在游戏开始前显示简介。我正在寻找一种方法来循环浏览长介绍而不按下任何键，但允许用户在任何时候按“Enter”以将其余文本跳过到最后。长长的介绍会在屏幕上滚动文本，但如果您要播放多次，这可能会很乏味。

到目前为止，我已经尝试在 while 循环和 if 语句中使用 Console.ReadKey 和 Console.Keyavailable，但有点卡住了。因为目前 foreach 语句没有处于任何循环中，只是打印直到完成。

//Long Intro
            foreach (char i in introText1)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            //Different colour to show importance of ship parts
            Console.ForegroundColor = ConsoleColor.Yellow;
            foreach (char i in introText2)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            Console.ForegroundColor = ConsoleColor.White;
            foreach (char i in introText3)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            //Different colour to show importance of oxygen
            Console.ForegroundColor = ConsoleColor.Cyan;
            foreach (char i in introText4)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            Console.ForegroundColor = ConsoleColor.White;
            foreach (char i in introText5)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            foreach (char i in introText6)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }
            //Quick guide to help menu
            Console.ForegroundColor = ConsoleColor.Green;
            foreach (char i in introText7)
            {
                Console.Write(i);
                Thread.Sleep(1);
            }

            //Quick Intro
            Console.WriteLine(introText1);
            Console.ForegroundColor = ConsoleColor.Yellow;
            Console.WriteLine(introText2);
            Console.ForegroundColor = ConsoleColor.White;
            Console.WriteLine(introText3);
            Console.ForegroundColor = ConsoleColor.Cyan;
            Console.WriteLine(introText4);
            Console.ForegroundColor = ConsoleColor.White;
            Console.WriteLine(introText5);
            Console.WriteLine(introText6);
            Console.ForegroundColor = ConsoleColor.Green;
            Console.WriteLine(introText7);

最终提示用户查看他们是否想首先查看介绍，因为这是获得所需效果的最简单方法。

            Console.WriteLine("Press ENTER to view intro");
            Console.WriteLine("Press Q to view quick intro");
            Console.WriteLine("Press S to skip intro");
            string temp1 = Console.ReadLine().ToUpper();
            if (temp1 == "Q")
            {
                Console.Clear();
                Console.Write(introText1);
                Console.ForegroundColor = ConsoleColor.Yellow;
                Console.Write(introText2);
                Console.ForegroundColor = ConsoleColor.White;
                Console.Write(introText3);
                Console.ForegroundColor = ConsoleColor.Cyan;
                Console.Write(introText4);

有很多方法可以做到这一点。这是Task和CancelationToken

using var cts = new CancellationTokenSource();
var token = cts.Token;

_ = Task.Run(async () =>
{
   var i = 0;
   // some fake loop
   while (!token.IsCancellationRequested)
   {
      Console.WriteLine(i++);
      await Task.Delay(1000);
   }
});

Console.WriteLine("press any key to stop");
Console.ReadKey();
cts.Cancel();
Console.WriteLine("Finished");

输出

press any key to stop
0
1
2
Finished
