In my application, a user enters two dates. A scheduled start date, and a scheduled end date. We have to take those dates, and populate 4 fields, based on the difference.

So, lets say he selects 1st Jan, 2010 as a start, and 2nd of March, 2011 as the end, we need to end up with:

Years: 1 Months: 2 Weeks: 0 Days 1

Meaning the total duration is 1 year, 2 months and 1 day.

Is there a standard way of doing this? Or would I need to write a method that has a lot of pretty tricky logic to work it out? I was hoping I'd be lucky, and there would be a date-diff type .Net class available.

c# .net date timespan
