利用goto，進行氣泡排序

                int[] list = new int[9] { 2, 4, 6, 7, 1, 9, 3, 8, 5 };
                int temporarily;
                Boolean  flag = true ; 
                int i=1;
                int j=1;
                for1:
                flag =false  ;
                j = 1;
                for2:                
                if (list[j] < list[j - 1])
                {    
                    temporarily  = list[j];
                    list[j] = list[j - 1];
                    list[j - 1] = temporarily;
                    flag = true ;
                }
                if (j<9-i)
                {
                    j += 1;
                    goto for2;
                }
                if (i < 8 && flag == true )
                {
                    i += 1;
                    goto for1;
                }
                j = 0;
                for3:
                Console.Write(list[j] + " ");
                j++;
                if (j < 9)
                    goto for3;
