Swith case

Swith case必须与break一起使用

Break是跳转语句。与swith case连用的时候是跳出最近的{}

例如//Console.WriteLine("请输入月份");

            //int y = int.Parse(Console.ReadLine ());

            //Console.WriteLine("请输入几号");

            //int h = int.Parse(Console.ReadLine());

            //int y1 = 31, y2 = 28, y3 = 31, y4 = 30, y5 = 31, y6 = 30, y7 = 31, y8 = 31, y9 = 30, y10 = 31, y11 = 30;

           

            //switch (y)

            //{

            //    case 1:

            //        Console.WriteLine("第"+h+"天");

            //        break;

            //    case 2:

            //        Console.WriteLine("第"+(y1+h)+"天");

            //        break;

            //    case 3:

            //        Console.WriteLine("第" +(y1+y2+ h)+ "天");

            //        break;

            //    case 4:

            //        Console.WriteLine("第" + (y1 +y2+y3+ h) + "天");

            //        break;

 

            //    case 5:

            //        Console.WriteLine("第" +(y1+y2+y3+y4+ h) + "天");

            //        break;

            //    case 6:

            //        Console.WriteLine("第" + (y1 +y2+y3+y4+y5+ h) + "天");

            //        break;

            //    case 7:

            //        Console.WriteLine("第" +(y1+y2+y3+y4+y5+y6+ h) + "天");

            //        break;

            //    case 8:

            //        Console.WriteLine("第" + (y1 +y2+y3+y4+y5+y6+y7+ h) + "天");

            //        break;

            //    case 9:

            //        Console.WriteLine("第" + (y1 + y2 + y3 + y4 + y5 + y6 + y7 +y8+ h) + "天");

            //        break;

            //    case 10:

            //        Console.WriteLine("第" + (y1 + y2 + y3 + y4 + y5 + y6 + y7 + y8+y9 + h) + "天");

            //        break;

            //    case 11:

            //        Console.WriteLine("第" + (y1 + y2 + y3 + y4 + y5 + y6 + y7 + y8 + y9+y10 + h) + "天");

            //        break;

            //    case 12:

            //        Console.WriteLine("第" + (y1 + y2 + y3 + y4 + y5 + y6 + y7 + y8 + y9 +y10+y11+ h) + "天");

            //        break;

            //    default :

            //        Console.WriteLine("您的输入有误！");

            //        break;

            //}

            //Console.ReadLine();
