I've to detect if two time periods are overlapping.
Every period has a start date and an end date.
I need to detect if my first time period (A) is overlapping with another one(B/C).
In my case, if the start of B is equal to the end of A, they are not overlapping(the inverse too)
I found the following cases:
So actually I'm doing this like this:
tStartA < tStartB && tStartB < tEndA //For case 1 OR tStartA < tEndB && tEndB <= tEndA //For case 2 OR tStartB < tStartA && tEndB > tEndA //For case 3
(The case 4 is taken in account either in case 1 or in case 2)
It works, but it seems not very efficient.
So, first is there an existing class in c# that can modelize this(a time period), something like a timepsan, but with a fixed start date.
Secondly: Is there already a c# code(like in the Datetime class) which can handle this?
Third: if no, what would be your approach to make this comparison the most fast?
