方法一: //最具有技術(shù)含量的一種
int days = System.Threading.Thread.CurrentThread.CurrentUICulture.Calendar.GetDaysInMonth(DateTime.Now.Year ,DateTime.Now.Month);
方法二://最奇怪的一種
DateTime dtNow = DateTime.Today;
int days = dtNow .AddDays(1 - dtNow .Day).AddMonths(1).AddDays(-1).Day;
方法三://最常規(guī)的寫法
DateTime dtNow = DateTime.Now; int days = DateTime.DaysInMonth(dtNow.Year ,dtNow.Month);
