//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 = {“*”,”月朔”,”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”};
