I need to get date from datetime in linq like this:

var items = db.Students.ToList().Select(u => new { bi = u.Birthday.Date });

but items in grid are displayed as follows:

I've seen other questions:

Question1: Linq - Select Date from DateTime

but when I edit code Similarly,

                var items = (from xx in db.Students                                     
                                 select new
                                 {
                                    EntityFunctions.TruncateTime(xx.Birthday)
                                 }).ToList();

I got a error in code!!

回答1:

As you have been told before in your other questions; when you display your grid at some point DateTime.ToString() is called, this results in a default behavior of displaying date and time. The DateTime.Date property simply returns the date part of the DateTime as a DateTime; in other words it returns the same thing but with the time set to exactly 12:00 AM.

To get the only the date as a string, you want to call DateTime.ToShortDateString, see here: https://msdn.microsoft.com/en-us/library/system.datetime.toshortdatestring(v=vs.110).aspx

In short this has nothing to do with Linq, the problem occurs when you try to display your DateTime object within your grid and as such needs to be solved by adjusting the formatting of the grid cells.
