Solution 2

What you should use is the Timespan Structure[^].

You would use something like this:

C#

Timespan result = DtpDateRetour.Value - DtpDateLocation.Value;
TbnbJourLocation.Text = Convert.ToInt32( result.TotalDays + 0.5 ).ToString();

This solution is an additional answer to Marcus's answer.

Here is another way that you can apply:

C#

TimeSpan dateDifference = new TimeSpan();
DateTime beginDate = DtpDateRetour.SelectedDate;
DateTime endDate = DtpDateLocation.SelectedDate;
dateDifference = beginDate.Subtract(endDate);

Good luck,
OI

I would also write subtraction operator "-" instead "Subtract", would be much more readable. OP also probably need a reference to format strings to format TimeSpan value as a string.

Solution 4

You can get days difference between two dates using TimeSpan

TimeSpan ts = DtpDateRetour.Value.Subtract(DtpDateLocation.Value);
TbnbJourLocation.Text = ts.Days.ToString();
