模拟录音和播放的过程

        控制台有一个强大的类Console，它包含了很多的方法，使控制台看起来不是那么的死板。其中Beep（）方法就可以实现音频播放的功能。

        一下是实现发音的一个方法，传入的参数为一个字符型的，因为要获取的是用户按下键盘上的哪个键。

        static void Play(char ch)
        {
            switch (ch)
            {
                case '1':
                    Console.BackgroundColor = ConsoleColor.Blue;     //改变其背景的颜色
                    Console.Clear();
                    i = 1;
                    Console.Beep((i + 13) * 37, 200);                                   //Beep()方法的使用
                    break;
                case '2':

                    Console.BackgroundColor = ConsoleColor.Cyan;
                    Console.Clear();
                    i = 3;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '3':

                    Console.BackgroundColor = ConsoleColor.DarkBlue;
                    Console.Clear();
                    i = 5;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '4':

                    Console.BackgroundColor = ConsoleColor.DarkCyan;
                    Console.Clear();
                    i = 6;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '5':

                    Console.BackgroundColor = ConsoleColor.DarkGray;
                    Console.Clear();
                    i = 8;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '6':

                    Console.BackgroundColor = ConsoleColor.DarkGreen;
                    Console.Clear();
                    i = 10;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '7':

                    Console.BackgroundColor = ConsoleColor.DarkMagenta;
                    Console.Clear();
                    i = 12;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                case '8':

                    Console.BackgroundColor = ConsoleColor.Gray;
                    Console.Clear();
                    i = 15;
                    Console.Beep((i + 13) * 37, 200);
                    break;
                default:
                    Console.BackgroundColor = ConsoleColor.DarkYellow;
                    Console.Clear();
                    i = 1;
                    Console.Beep((i + 13) * 37, 200);
                    break;
            }
        }

 

          怎样获取用户在键盘上输入的键，录音结束标记是哪个，这都是需要考虑的。

            while (true)
            {
                Console.WriteLine("a.开始录音 b.播放录音");
                char choose = Convert.ToChar(Console.ReadLine());

                switch (choose)
                {
                    case 'a':

                        ConsoleKeyInfo key1 = new ConsoleKeyInfo();
                        while (key1.KeyChar != 's')                         //当用户输入s时，表明输入结束
                        {
                            key1 = Console.ReadKey(true);                     //获取用户输入的键值
                            a = key1.KeyChar;
                            list.Add(a);
                            Console.Write(a);
                            Play(a);

                        }

                        break;

                    case 'b':
                        if (list.Count > 0)
                        {
                            foreach (char ch in list)
                            {
                                Play(ch);
                            }
                        }

                        else
                        {
                            Console.WriteLine("你还没有录音，请先录音！");

                        }
                        break;
                }

 

Console类中的好多方法，属性都值得我们去深入的研究！
