本文实例讲述了C#实现农历日历的方法。分享给大家供大家参考。
具体实现方法如下:
private static string []TianGan = {"甲","乙","丙","丁","戊","己","庚","辛","壬","癸"};
//地支
private static string []DiZhi = {"子","丑","寅","卯","辰","巳","午","未","申","酉","戌","亥"};
//十二生肖
private static string []ShengXiao = {"鼠","牛","虎","兔","龙","蛇","马","羊","猴","鸡","狗","猪"};
//农历日期
private static string []DayName = {"*","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"};
//农历月份
private static string []MonthName = {"*","正","二","三","四","五","六","七","八","九","十","十一","腊"};
//公历月计数天
private static int []MonthAdd = {0,31,59,90,120,151,181,212,243,273,304,334};
//农历数据
private static int []LunarData = {2635,333387,1701,1748,267701,694,2391,133423,1175,396438 ,3402,3749,331177,1453,694,201326,2350,465197,3221,3402 ,400202,2901,1386,267611,605,2349,137515,2709,464533,1738 ,2901,330421,1242,2651,199255,1323,529706,3733,1706,398762 ,2741,1206,267438,2647,1318,204070,3477,461653,1386,2413 ,330077,1197,2637,268877,3365,531109,2900,2922,398042,2395 ,1179,267415,2635,661067,1701,1748,398772,2742,2391,330031 ,1175,1611,200010,3749,527717,1452,2742,332397,2350,3222 ,268949,3402,3493,133973,1386,464219,605,2349,334123,2709 ,2890,267946,2773,592565,1210,2651,395863,1323,2707,265877};
