check if a date falls in the next 24 hours with c #

Question

it is possible with C # test whether the DateTime " 01/29/2016 16:22:00 " is included in the next 24 hours? I have a date that is " 01/28/2016 15:30 " ( DateTime.Now ) and I 'd like to know if it is within the range going forward 24 hours. I hope I explained .

You want to know if `DateTime.Now` is within the next 24 hours? — Tim Schmelter, Jan 28 '16 at 15:26

(yourDatetime - DateTime.Now) <= TimeSpan.FromHours(24)

And if your time was 5 years ago? – jmoreno Jan 28 '16 at 15:41
It will not work if the `yourDatetime = DateTime.Now.AddHours(-26)`; You can use `Math.Abs`. – Farhad Jabiyev Jan 28 '16 at 15:43

You can use AddHours:

var myDateTime = ...
var now = DateTime.Now;

if (myDateTime <= now.AddHours(24)
    && myDateTime >= now.AddHours(-24))
{

}

Also keep in mind that DateTime is immutable and they cannot be modified after creation. That is why AddHours returns a new instance.

Update: After seeing M.kazem's answer I have though that you can also use that:

Math.Abs(myDateTime.Subtract(DateTime.Now).TotalHours) <= 24
