C#通用节气类库农历类（很全面）
自己整理的，专业分享学习高质量代码，每周期布置学习任务，激发学习C#兴趣！
用法：
DateTime dt = mc.SelectionStart;
c = new EcanChineseCalendar(dt);
StringBuilder dayInfo = new StringBuilder();
dayInfo.Append(阳历： + c.DateString + r );//阳历日期
dayInfo.Append(农历： + c.ChineseDateString + r );//农历日期
dayInfo.Append(星期： + c.WeekDayStr);//星期
dayInfo.Append(时辰： + c.ChineseHour + r );//时辰
dayInfo.Append(属相： + c.AnimalString + r );//属相
dayInfo.Append(节气： + c.ChineseTwentyFourDay + r );//节气
dayInfo.Append(前一个节气： + c.ChineseTwentyFourPrevDay + r );//前一个节气
dayInfo.Append(下一个节气： + c.ChineseTwentyFourNextDay + r );//下一个节气
dayInfo.Append(节日： + c.DateHoliday + r );//节日
dayInfo.Append(干支： + c.GanZhiDateString + r );//干支
