On your first attempt remember that DateTime.Now includes minutes, seconds and milliseconds. Try using DateTime.Now.Date instead (as you did on the second attempt)

I tried DateTime.Now.Date
i got 0 records :(

What type is DateWorked and do you actually have any records with today's date on them (you'd be surprised how many times that is an issue :-))

DateWorked type is DateTime and yes i have records with todays date

Can you please try this and see if it works :

DetailDB.Where(x => x.DateWorked.Value.Date == null || x.DateWorked.Value.Date == DateTime.Now.Date);

Try:

C#

var xx = DetailDB.Where(x => x.DateWorked == null ? false : ((DateTime)x.DateWorked).Date == DateTime.Now.Date);
