        DateTime date1 = new DateTime(2011, 1, 1, 12, 0, 0);
        DateTime date2 = new DateTime(2011, 1, 3, 13, 0, 0);
        TimeSpan ts = date2 - date1;

        double hours = ts.TotalHours;

Use TotalHours instead of Hours. Note that the result is a double - you can just cast it to int to get the whole number of hours. (Check what behaviour you want if the result is negative though...)

From the docs for Hours:

Property Value: The hour component of the current TimeSpan structure. The return value ranges from -23 through 23

You don't want the hour component - you want the whole time span, expressed in hours.
