Answer 1

var d1 = new DateTime(year1, month1, day1);
var d2 = new DateTime(year2, month2, day2);
TimeSpan t = d2 - d1;
var elapsedDays = t.Days;

Answer 2

Try this:

TimeSpan difference = endTime.Subtract(startTime); 
int numDays = difference.Days;

Answer 3

Subtracting a DateTime (or a DateTimeOffset) from another will result in a TimeSpan. The TimeSpan structure has a TotalDays property which should give you what you're looking for.

Here's a link to the MSDN page for TimeSpan.

Answer 4

(new DateTime(endYear, endMonth, endDay) - new DateTime(startYear, startMonth, startDay)).TotalDays

Answer 5

DateTime checkin //set to checkin date
DateTime checkout //set to checkout date
TimeSpan ts = checkout.Subtract(checkin);
int dayDifference = ts.TotalDays; //this is your days
