Get total days (int) between DateTime.Now and a certain DateTime [closed]

Question

How can I get the total days as int between DateTime.Now and a specific DateTime? Can this be done using LINQ?

Answer 1

You can simply calculate the difference using the following method:

DateTime a = ;//some datetime
DateTime now = DateTime.Now;
TimeSpan ts = now-a;
int days = Math.Abs(ts.Days);

Answer 2

Simply subtract two DateTimes from each other, into a TimeSpan, and get the TotalDays component from it.

TimeSpan diff = DateTime.Now - OtherDateTime
int days = (int)Math.Abs(Math.Round(diff.TotalDays));

It is rounded to remove the fraction caused by the hours/minutes/seconds, and the absolute value is given so you get the exact change.
