C#（99）：中文日历Calendar

一、层次结构

      Object<-----Calendar<-----EastAsianLunisolarCalendar<-----ChineseLunisolarCalendar(农历)

二、用法

1、支持的最大，最小日期

System.Globalization.ChineseLunisolarCalendar cc =new System.Globalization.ChineseLunisolarCalendar();
s1=cc.MinSupportedDateTime.ToString("");//02/19/1901 00:00:00
s2=cc.MaxSupportedDateTime.ToString("");//01/28/2101 23:59:59

2、单位农历天数

System.Globalization.ChineseLunisolarCalendar cc =new System.Globalization.ChineseLunisolarCalendar();
s1=cc.GetMonthsInYear(DateTime.Now.Year).ToString();//12，一年中有几个月，13表示当年有闰月。
s2=cc.GetDaysInYear(DateTime.Now.Year).ToString();//354，一年中有多少天
s3=cc.GetDaysInMonth(DateTime.Now.Year,DateTime.Now.Month).ToString();//29 ，当月中有多少天

3、天干、地支

System.Globalization.ChineseLunisolarCalendar cc =new System.Globalization.ChineseLunisolarCalendar();
s1=cc.GetSexagenaryYear(DateTime.Now ).ToString();//36，天干
s2=cc.GetTerrestrialBranch(36).ToString();//12，地支

4、农历年、月、日

System.Globalization.ChineseLunisolarCalendar cc =new System.Globalization.ChineseLunisolarCalendar();
s1=cc.GetYear(DateTime.Now).ToString();//;2019
s2=cc.GetMonth(DateTime.Now).ToString();//;5，注意：其返回值为1-13的数，如果该年四月有闰月，4月返回4，闰4月则返回5
s3=cc.GetDayOfMonth(DateTime.Now).ToString();//;23

5、闰年与闰月

System.Globalization.ChineseLunisolarCalendar cc =new System.Globalization.ChineseLunisolarCalendar();
s1=cc.IsLeapYear(DateTime.Now.Year).ToString();//;False
s2=cc.GetLeapMonth(DateTime.Now.Year).ToString();//;0，注意：表示所闰月份。如果返回5，表示闰4月。

6、显示农历大写月份

string[] monthName = {"正",  "二", "三", "四", "五", "六", "七", "八", "九", "十", "东", "腊" };
System.Globalization.ChineseLunisolarCalendar cc = new System.Globalization.ChineseLunisolarCalendar();
int currentMonth = cc.GetMonth(DateTime.Today);
int leapMonth = cc.GetLeapMonth(DateTime.Today.Year);
string realMonth;
if (currentMonth < leapMonth)
    realMonth = monthName[currentMonth];
else if (currentMonth == leapMonth)
    realMonth = "闰" + monthName[currentMonth - 1];
else
    realMonth = monthName[currentMonth - 1];
s1 = realMonth.ToString();//;五
