代码如下:

void Main()
{
//农历转阳历
var lunar = new System.Globalization.ChineseLunisolarCalendar();
var date = lunar.ToDateTime(, , , , , , ); //将2020年正月初一转为阳历,如果闰月,则月份加1。2020年有闰四月,则闰四月传5, 本年度之后的月份依次类推
Console.WriteLine(date); //阳历转阴历
date = new DateTime(, , );
var leapMonth = lunar.GetLeapMonth(date.Year); //获取当年农历闰月
if (leapMonth == ) //当年没有闰月
{
var lunarDate = lunar.GetYear(date) + "年" + lunar.GetMonth(date) + "月" + lunar.GetDayOfMonth(date) + "日";
Console.WriteLine(lunarDate);
}
else //当年有闰月
{
//因闰月之后月份都加了一,所以要减一
var month = lunar.GetMonth(date) >= leapMonth ? lunar.GetMonth(date) - : lunar.GetMonth(date);
var lunarDate = lunar.GetYear(date) + "年" + (lunar.GetMonth(date) == leapMonth ? "闰" : string.Empty) + month + "月" + lunar.GetDayOfMonth(date) + "日";
Console.WriteLine(lunarDate);
}
}
