ASP.NET顯示農歷時間

今天看了下之前寫的網頁，突然想起應該加個時間的。
於是准備就直接DateTime.Now一下，再一想，還是顯示農歷吧，畢竟這是咱們中國人自己的時間，
想想現在很多人不看日歷根本都都不知道農歷時間了。

這段代碼也是從網上找來的，基本沒怎麼改。
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();
}

使用：
<table style="">
<tr valign="bottom">
<td valign="bottom"> <%=ForignTimeNow%><br /></td>>
</tr>
<tr valign="bottom">
<td valign="bottom"> <%=ChineseTimeNow %></td>
</tr>
