ASP.NET显示农历时间的方法
本文实例讲述了asp.net显示农历时间的方法。分享给大家供大家参考。具体实现方法如下：
cs部分代码如下:
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();
}
/// <summary>
/// 获取一个公历日期对应的完整的农历日期
/// </summary>
/// <param name="time">一个公历日期</param>
/// <returns>农历日期</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>
/// 获取一个公历日期的农历干支纪年
/// </summary>
/// <param name="time">一个公历日期</param>
/// <returns>农历干支纪年</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>
/// 获取一个公历日期的农历年份
/// </summary>
/// <param name="time">一个公历日期</param>
/// <returns>农历年份</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>
/// 获取一个公历日期的农历月份
/// </summary>
/// <param name="time">一个公历日期</param>
/// <returns>农历月份</returns>
public string getmonth(datetime time)
{
int month = calendar.getmonth(time);
int year = calendar.getyear(time);
int leap = 0;
//正月不可能闰月
for (int i = 3; i <= month; i++)
{
if (calendar.isleapmonth(year, i))
{
leap = i;
break; //一年中最多有一个闰月
}
}
if (leap > 0) month--;
return (leap == month + 1 ? "闰" : "") + chinesemonthname[month - 1];
}
/// <summary>
/// 获取一个公历日期的农历日
/// </summary>
/// <param name="time">一个公历日期</param>
/// <returns>农历日</returns>
public string getday(datetime time)
{
return chinesedayname[calendar.getdayofmonth(time) - 1];
}
前台部分代码如下：
<tr valign="bottom">
<td valign="bottom"> <%=forigntimenow%><br /></td>>
</tr>
<tr valign="bottom">
<td valign="bottom"> <%=chinesetimenow %></td>
</tr>
</table>
希望本文所述对大家的asp.net程序设计有所帮助。
