今天看了下之前写的网页，突然想起应该加个时间的。
于是准备就直接DateTime.Now一下，再一想，还是显示农历吧，毕竟这是咱们中国人自己的时间，
想想现在很多人不看日历根本都都不知道农历时间了。

这段代码也是从网上找来的，基本没怎么改。

public string ChineseTimeNow = "";
        public string ForignTimeNow = "";
        private static ChineseLunisolarCalendar calendar = new ChineseLunisolarCalendar();
        private static string ChineseNumber = "〇一二三四五六七八九";
        public const string CelestialStem = "甲乙丙丁戊己庚辛壬癸";
        public const string TerrestrialBranch = "子丑寅卯辰巳午未申酉戌亥";
        public static readonly string[] ChineseDayName = new string[] {
            "初一","初二","初三","初四","初五","初六","初七","初八","初九","初十",
            "十一","十二","十三","十四","十五","十六","十七","十八","十九","二十",
            "廿一","廿二","廿三","廿四","廿五","廿六","廿七","廿八","廿九","三十"};
        public static readonly string[] ChineseMonthName = new string[] { "正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二" };

        override protected void Page_Load(object sender, EventArgs e)
        {
            base.Page_Load(sender, e);
            userName = Session["Admin"].ToString();
            ChineseTimeNow=GetChineseDate(DateTime.Now);
            ForignTimeNow = DateTime.Now.GetDateTimeFormats('D')[0].ToString();
        }

            string strD = GetDay(time);
            string strSB = GetStemBranch(time);
            string strDate = strY + "(" + strSB + ")年 " + strM + "月 " + strD;
            return strDate;

            string stemBranch = CelestialStem.Substring(sexagenaryYear % 10 - 1, 1) + TerrestrialBranch.Substring(sexagenaryYear % 12 - 1, 1);
            return stemBranch;
        }

            }
            if (leap > 0) month--;
            return (leap == month + 1 ? "闰" : "") + ChineseMonthName[month - 1];
