Compare DateTime Lists, c# linq

I have a List in C#

List<Dates>

public class Dates
{
    public DateTime Start {get; set;}
    public DateTime End {get; set;}
}

In List:

Start - End

  1. 2014-03-17 09:00:00 - 2014-03-17 10:00:00
  2. 2014-03-17 10:59:59 - 2014-03-17 11:44:59

How do I check if my startToCheck is between Start, the same to endToCheck to End to that list?

For example: 

startToCheck = 2014-03-17 11:00:00
endToCheck = 2014-03-17 12:00:00

Obviously, my startToCheck is in List nr2, but is not find it.

I tried 

if (Start <= startToCheck && End >= endToCheck)

But is not working... Any help, please?

Thanks

It sounds like you are trying to determine if any of the Dates value in the list are between that range. If so you are looking for the Any method

if (theList.Any(x => x.Start <= endToCheck && x.End >= startToCheck) { 
  ...
}

If you want to detect all overlaps:

yourList.Where(x=> x.Start <= endToCheck && x.End >= startToCheck)
