C# 趣味小程序（2）——用字母表示的26进制数

 1为A，2为B……26为Z， 27为AA以此类推

{
         StringBuilder sbW = null;
            for (int i = 1; i < 500;i++)//五百以内
            {
                sbW = new StringBuilder();
                int n = i;
                while (n != 0)
                {
                    if (n % 26 == 0)
                    {
                        sbW.Insert(0, 'Z');
                        n = n / 26 - 1;
                    }
                    else
                    {
                        sbW.Insert(0, (char)((n % 26 - 1) + 'A'));
                        n /= 26;
                    }
                }
                    Console.WriteLine(i.ToString() +"/t" +sbW.ToString());
            }
