这是否回答了你的问题：
public string ChineseZodiac(System.DateTime date)
{
System.Globalization.EastAsianLunisolarCalendar cc =
new System.Globalization.ChineseLunisolarCalendar();
int sexagenaryYear = cc.GetSexagenaryYear(date);
int terrestrialBranch = cc.GetTerrestrialBranch(sexagenaryYear);
// string[] years = "rat,ox,tiger,hare,dragon,snake,horse,sheep,monkey,fowl,dog,pig".Split(',');
// string[] years = "Rat,Ox,Tiger,Rabbit,Dragon,Snake,Horse,Goat,Monkey,Rooster,Dog,Pig".Split(',');
// string[] years = new string[]{ "rat", "ox", "tiger", "hare", "dragon", "snake", "horse", "sheep", "monkey", "fowl", "dog", "pig" };
string[] years = new string[]{ "Rat", "Ox", "Tiger", "Rabbit", "Dragon", "Snake", "Horse", "Goat", "Monkey", "Rooster", "Dog", "Pig" };
return years[terrestrialBranch - 1];
} // End Function ChineseZodiac
