Question

Overlap exists between DateRange1 and DateRange2

DateRange1:        |-----------|
DateRange2:                |-------|

Overlap does not exist between DateRange3 and DateRange4

DateRange3:    |------|
DateRange4:                 |-------|

I have a query that checks if there is an overlap, but it’s a little hairy. It involves checking each DateRange border and uses a lot of <‘s and >’s.

I was wondering if you could say like, if DateRange1.Union(DateRange2) != null, do stuff.
Just something to make my code more readable and less hairy.

Thanks!

If you can add a IncludedDates property (IEnumerable<DateTime>), it should be pretty easy.

DateRange1.IncludedDates.Intersect(DateRange2.IncludedDates).Any()
