小小的钢琴系统

今天学习了Console.Beep（）这个方法，然后利用这个方法做了一个小小的钢琴系统，感觉还挺有意思的，下面是主要代码实现：

 while (true)
            {
               
                char i=Console.ReadKey().KeyChar;//输入按键
               
                
                switch (i)
                {
                     
                    case '1':
                        Console.BackgroundColor = ConsoleColor.DarkBlue;   //按键的颜色                    
                        Console.Beep(518,100); //设置  Console.Beep里面的参数，发出  不同的声音，模拟钢琴的八个发音键          
                        break;
                    case '2':
                        Console.Beep(592, 100)
                        Console.BackgroundColor = ConsoleColor.DarkGreen;
                      
                        break;
                    case '3':
                        Console.Beep(666, 100);
                        Console.BackgroundColor = ConsoleColor.DarkRed;
                        break;
                    case '4':
                        Console.Beep(703, 100);
                        Console.BackgroundColor = ConsoleColor.DarkYellow;
                        break;
                    case '5':
                        Console.Beep(777, 100);
                        Console.BackgroundColor = ConsoleColor.DarkMagenta;
                        break;
                    case '6':
                        Console.Beep(851, 100);
                        Console.BackgroundColor = ConsoleColor.DarkCyan;
                        break;
                    case '7':
                        Console.Beep(925, 100);
                        Console.BackgroundColor = ConsoleColor.DarkGray;
                        break;
                    case '8':
                        Console.Beep(1037, 100);
                        Console.BackgroundColor = ConsoleColor.DarkGray;
                        break;
                }

            }

虽然代码很简单，实现的功能也很简单，但是通过学习一个简单的方法，然后能够扩展到别的方面，然后还做出了这么一个小小的系统，感觉还是很不错的，系统还很不完善，以后会继续改进的。
