Hi,

In VB we have DateDiff to calculate the days difference between 2 dates,
I was wondering if we

have something like that in C#?

I want to calculate for example the days difference betwenn 19/06/2007
and 12/06/2007.. it

should return 7

Cheers!

Try:

(date2 - date1).TotalDays;

Claudia,

You should just be able to subtract the two datetime instances and get a
TimeSpan instance. From that, you can use the Days property to find the
number of days between the two dates.

If the DateDiff has logic that the standard operations on DateTime does
not provide, then you can add a reference to Microsoft.VisualBasic.dll and
then use the DateDiff function like you would in VB.
 
you can use dt1.Subtract(dt2).Days to get days diff

Just a note on .Days vs .TotalDays

If (dt1 - dt2) is 7 days, 12 hours, TotalDays will give 7.5, .Days
will give 7
 
Claudia,

As you can see is it not clear wat for you is for you the difference between
2 dates, is that in hours 48 hours or just that from 1 january until 3
january is 2 dates.

(I would avoid the timespan by the day because it has only a limited amount
of days you can get returned).

The maximu value of TimeSpan is 10675199.02:48:05.4775808
I suppose this is enough for most cases ;-)

dt1.Subtract(dt2)).Days should be enough for the req it seems.
