如何在ASP.NET中显示基于年份(考虑leap年)的月份的最后日期

how to display the last date of the month based on the year (taking into account leap year)in ASP.NET

推荐答案

让.Net处理此问题您:

Let .Net handle this for you:

public DateTime LastDayOfMonthFromDateTime(DateTime dateTime)
{
   DateTime firstDayOfTheMonth = new DateTime(dateTime.Year, dateTime.Month, 1);
   return firstDayOfTheMonth.AddMonths(1).AddDays(-1);
}

public int GetDaysInMonth(int month, int year)
{
DateTime date = DateTime.Now;
if (month == 12) date = new DateTime(year + 1, 1, 1);
else date = new DateTime(year, month + 1, 1);
return date.AddDays(-1).Day;
}
