Answer 1

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.
