Have you tried TimeSpan?

TimeSpan tm= dt1 - dt2;

[loliana]

I tried in this function but it didn't any thing...
I have this func:

public static string   DateDiff( DateTime t2,DateTime t1)
        {
            TimeSpan  diffResult = t2.Subtract(t1);
            int i = diffResult.days;
            
       
            return i.ToString();

        }

but dont know what i have to do to get the days numb..

Have you tried diffResult.TotalDays? .Days only returns the day portion of the timespan, so if the difference between the dates was 1 month, 1 week and 1 day then .Days would return 1 whereas TotalDays would return 39 or something close to it depending on the dates you were comparing.
