C# Get Empty partion of the date time from List date time

Question

i have in c# this list of the Rendez-vous:

ID Date_Start Date_End
1. 18/11/2016 08:00 18/11/2016 14:00
2. 18/11/2016 09:00 18/11/2016 11:30
3. 18/11/2016 14:00 18/11/2016 16:30
4. 18/11/2016 17:30 18/11/2016 19:00

How I can check the part of time is busy or no ? for exemple how to check the part time from 18/11/2016 11:30 to 18/11/2016 14:00 is busy ?

thanks for your Response.

@MacakM I think OP is actually looking for an overlap of date ranges, although it's unclear — ChaseMedallion, Nov 19 '16 at 15:13

It's hard to tell exactly what you're looking for from your question. My interpretation is that you want to know whether a given range of dates overlaps with any range in your list. Here's the code to do that:

Rendezvous[] rendezvous = ... // you already have this
DateTime startTime = ... // e. g. 18/11/2016 11:30
DateTime endTime = ... // e. g. 18/11/2016 14:00
var isBusy = rendezvous.Any(r => !(endTime < r.Date_Start || startTime > r.Date_End));
