        case 1: 
          Console.WriteLine("In case 1"); 
          goto case 3;

          Console.WriteLine("In case 2"); 
          goto case 1; 
        case 3: 
          Console.WriteLine("In case 3"); 
          goto default; 
        default: 
          Console.WriteLine("In default"); 
          break;
