C#教程之C#实现带阴历显示的日期代码

本文实例讲述了C#实现带阴历显示的日期代码，分享给大家供大家参考。具体方法如下：

这是一个用于酒店预定功能的带日期控件，类似去哪网酒店预定，由于需要设置节假日不同时期内的价格，因此需要自己写个时间控件。在此分享下写时间控件过程中用到的农历显示类。

复制代码代码如下:

public class CnCalendar
{
static ChineseLunisolarCalendar cCalendar = new ChineseLunisolarCalendar();
public static string GetChineseDateTime(DateTime datetime)
{
string strDate = datetime.Month + "月" + datetime.Day + "日";
int lyear = cCalendar.GetYear(datetime);
int lmonth = cCalendar.GetMonth(datetime);
int lday = cCalendar.GetDayOfMonth(datetime);
//获取闰月， 0 则表示没有闰月
int leapMonth = cCalendar.GetLeapMonth(lyear);
bool isleap = false;
if (leapMonth > 0)
{
if (leapMonth == lmonth)
{
//闰月
isleap = true;
lmonth--;
}
else if (lmonth > leapMonth)
{
lmonth--;
}
}
if (strDate == "1月1日")
{
return "元旦";
}
else if (strDate == "2月14日")
{
return "情人节";
}
else if (strDate == "3月8日")
{
return "妇女节";
}
else if (strDate == "3月12日")
{
return "植树节";
}
else if (strDate == "4月1日")
{
return "愚人节";
}
else if (strDate == "5月1日")
{
return "劳动节";
}
else if (strDate == "5月4日")
{
return "青年节";
}
else if (strDate == "6月1日")
{
return "儿童节";
}
else if (strDate == "8月1日")
{
return "建军节";
}
else if (strDate == "9月10日")
{
return "教师节";
}
else if (strDate == "10月1日")
{
return "国庆节";
}
else
{
if (lday == 1)
{
return "" +
string.Concat(isleap ? "闰" : string.Empty, GetLunisolarMonth(lmonth), "月") + "";
}
else
{
string strNongli = string.Concat(isleap ? "闰" : string.Empty, GetLunisolarMonth(lmonth), "月",
GetLunisolarDay(lday));
switch (strNongli)
{
case "正月初一":
return "春节";
case "正月十五":
return "元宵节";
case "五月初五":
return "端午节";
case "七月初七":
return "七夕";
case "八月十五":
return "中秋节";
case "九月初九":
return "重阳节";
case "腊月初八":
return "腊八节";
case "腊月二十四":
return "扫房节";
default:
return "" + GetLunisolarDay(lday) + "";
}
}
}
}
