ASP.NET顯示農歷時間改進版

編輯：ASP.NET基礎

本文實例講述了ASP.NET顯示農歷時間的方法，是前面一篇文章源碼的改進版。分享給大家供大家參考。具體如下：

前面有一篇取農歷時間http://www.jb51.net/article/57481.htm，不過沒有進行封裝使用起來需要手動修改。本次進行簡單封裝一下，可以直接進行調用。

代碼如下：

取農歷時間的類
復制代碼代碼如下:public class CountryDate
{
     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" };

     /// <summary>
     /// 獲取一個公歷日期對應的完整的農歷日期
     /// </summary>
     /// <param name="time">一個公歷日期</param>
     /// <returns>農歷日期</returns>
     public string GetChineseDate(DateTime time)
     {
         string strY = GetYear(time);
         string strM = GetMonth(time);
         string strD = GetDay(time);
         string strSB = GetStemBranch(time);
         string strDate = strY + "(" + strSB + ")年 " + strM + "月 " + strD;
         return strDate;
     }
     /// <summary>
     /// 獲取一個公歷日期的農歷干支紀年
     /// </summary>
     /// <param name="time">一個公歷日期</param>
     /// <returns>農歷干支紀年</returns>
     public string GetStemBranch(DateTime time)
     {
         int sexagenaryYear = calendar.GetSexagenaryYear(time);
         string stemBranch = CelestialStem.Substring(sexagenaryYear % 10 - 1, 1) + TerrestrialBranch.Substring(sexagenaryYear % 12 - 1, 1);
         return stemBranch;
     }

     /// <summary>
     /// 獲取一個公歷日期的農歷年份
     /// </summary>
     /// <param name="time">一個公歷日期</param>
     /// <returns>農歷年份</returns>
     public string GetYear(DateTime time)
     {
         StringBuilder sb = new StringBuilder();
         int year = calendar.GetYear(time);
         int d;
         do
         {
             d = year % 10;
             sb.Insert(0, ChineseNumber[d]);
             year = year / 10;
         } while (year > 0);
         return sb.ToString();
     }

     /// <summary>
     /// 獲取一個公歷日期的農歷月份
     /// </summary>
     /// <param name="time">一個公歷日期</param>
     /// <returns>農歷月份</returns>
     public string GetMonth(DateTime time)
     {
         int month = calendar.GetMonth(time);
         int year = calendar.GetYear(time);
         int leap = 0;

         //正月不可能閏月
         for (int i = 3; i <= month; i++)
         {
             if (calendar.IsLeapMonth(year, i))
             {
                 leap = i;
                 break; //一年中最多有一個閏月
             }

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

     /// <summary>
     /// 獲取一個公歷日期的農歷日
     /// </summary>
     /// <param name="time">一個公歷日期</param>
     /// <returns>農歷日</returns>
     public string GetDay(DateTime time)
     {
         return ChineseDayName[calendar.GetDayOfMonth(time) - 1];
     }
}

需要的using
復制代碼代碼如下:using System;
using System.Collections.Generic;
using System.Web;
using System.Text;
using System.Globalization;
調用：
復制代碼代碼如下:CountryDate cd = new CountryDate();
string ChineseTimeNow = cd.GetChineseDate(DateTime.Now);//農歷日期
string ForignTimeNow = DateTime.Now.GetDateTimeFormats('D')[0].ToString();//公歷日期

下面有一個測試的效果：

前台代碼：

復制代碼代碼如下:<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestCountryDate._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <table>
     <tr>
      <td><asp:Label ID="Label1" runat="server" Text="農歷時間"/></td>
      <td><asp:Label ID="lblCountryDate" runat="server"/></td>
     </tr>
     <tr>
      <td><asp:Label ID="Label2" runat="server" Text="公歷時間"/></td>
      <td><asp:Label ID="lblForignDate" runat="server"/></td>
     </tr>
    </table>
    <asp:Button ID="buttton1" runat="server" Text="顯示時間" OnClick="Button1_Click" />
    </div>
    </form>
</body>
</html>

後台代碼：
復制代碼代碼如下:public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        CountryDate cd = new CountryDate();
        string ChineseTimeNow = cd.GetChineseDate(DateTime.Now);//農歷日期
        string ForignTimeNow = DateTime.Now.GetDateTimeFormats('D')[0].ToString();//公歷日期

        lblCountryDate.Text = ChineseTimeNow;
        lblForignDate.Text = ForignTimeNow;
    }
}
