[转载]c#农历

转载自：http://www.cnblogs.com/zjfree/archive/2011/01/13/1934231.html

网上已经有很多C#的农历类，但看来都很复杂，其实C#中已经提供了中国的农历类ChineseLunisolarCalendar。但未提供节气和节日功能。

根据网上的方法字节写了一个中国农历类！

ChinaDate.GetChinaDate(DateTime dt) 获取农历日期

ChinaDate.GetYear(DateTime dt) 获取农历年份（包含天干地支和生肖信息）

ChinaDate.GetMonth(DateTime dt) 获取农历月份

ChinaDate.GetDay(DateTime dt) 获取农历日期

ChinaDate.GetSolarTerm(DateTime dt) 获取节气

ChinaDate.GetHoliday(DateTime dt) 获取公历节日

ChinaDate.GetChinaHoliday(DateTime dt) 获取农历节日
