Is there any easy way to increment a DateTime by monthly/yearly/daily units without having to parse it out like crazy?

Question

I need to set up billing cycles and process payments. So for example I will process a payment immediately and then set the next one up to process exactly one month from then

If you ever need to work with Quarter or WeekOfYear, Microsoft.VisualBasic.DateAndTime.

Otherwise, System.DateTime does everything you would typically need.
