Getting the total hours in a TimeSpan

Question

How can I subtract two dates and get the total hours of the TimeSpan object that is returned?

For example, if the TimeSpan is 2 days, the total hours are 48.

Answer 1

Then you want the TotalHours property of the TimeSpan object:

DateTime today = DateTime.Today;
DateTime twoDaysAgo = today.AddDays(-2.0);

// returns 48.0
double totalHours = (today - twoDaysAgo).TotalHours;
