DateTime t1 = Convert.ToDateTime("2006-1-6");
DateTime t2 = Convert.ToDateTime("2006-1-16");
int day=Math.Abs(((TimeSpan)(t1 - t2)).Days);

datediff(day,date1,date2)

3、
DateTime oldDate = new DateTime(2002,7,15);
DateTime newDate = DateTime.Now;
// Difference in days, hours, and minutes.
TimeSpan ts = newDate - oldDate;
// Difference in days.
int differenceInDays = ts.Days;
Console.WriteLine("Difference in days: {0} ", differenceInDays);
