// Create a TimeSpan representing 2.5 days.

TimeSpan timespan1 = new TimeSpan(2, 12, 0, 0);



// Create a TimeSpan representing 4.5 days.

TimeSpan timespan2 = new TimeSpan(4, 12, 0, 0);



// Create a TimeSpan representing 1 week.

TimeSpan oneWeek = timespan1 + timespan2;



// Create a DateTime with the current date and time.

DateTime now = DateTime.Now;



// Create a DateTime representing 1 week ago.

DateTime past = now - oneWeek;



// Create a DateTime representing 1 week in the future.

DateTime future = now + oneWeek;

مثال :‌ پیدا کردن اختلاف تعداد روزهای بین دو تاریخ :

DateTime dateFrom = DateTime.Parse("10/10/2007");

DateTime dateTo = DateTime.Parse("11/12/2007");

TimeSpan ts = dateTo - dateFrom;

int days = ts.Days;

و یا :

DateTime dtFirst = new DateTime(2007, 10, 10);

DateTime dtSecond = new DateTime(2007, 11, 12);

TimeSpan diffResult = dtSecond.Subtract(dtFirst);
