Linq选择日期+ 1的时间

Question

In my SQL 2008 R2, I have this table:

I have create the LINQ syntax to select all hours that greater than computer hour:

 public IList<LS_CLIENTHORRAIRE> Get_All_Obj(string CLIENT_ID)
        {
            try
            {
                IList<LS_CLIENTHORRAIRE> LesListe;
                using (Soft8Exp_ClientEntities oEntite_T = new Soft8Exp_ClientEntities())
                {
                    int The_Hour = DateTime.Now.Hour;
                    var query = from o in oEntite_T.LS_CLIENTHORRAIRE where o.CLIENT_ID == CLIENT_ID && o.HORRAIRE > new TimeSpan(The_Hour, 00/*minutes*/, 00/*seconds*/) select o;
                    LesListe = query.ToList();
                }
                return LesListe;
            }
            catch (Exception excThrown)
            {
                throw new Exception("Err_02", excThrown);
            }
        }

and it is work fine:

• when the hour computer is 08:00 then it return 12:00 and 19:00 ,
• when the hour computer is 13:00 then it return 19:00 .

But now I want to change the program that look at the date also:

• when the hour computer is 08:00 then it return 12:00 and 19:00 and 05:00 .
• when the hour computer is 13:00 then it return 19:00 and 05:00 .
• when the hour computer is 20:00 then it return 05:00 .

Any idea ?

i have tried like this:

 DateTime The_Date = DateTime.Now.Date;
                    var query = from o in oEntite_T.LS_CLIENTHORRAIRE where o.CLIENT_ID == CLIENT_ID && The_Date.Add(o.HORRAIRE) > DateTime.Now select o;
                    LesListe = query.ToList(

);

but unfortunately it not work

Answer 1

var query = oEntite_T.LS_CLIENTHORRAIRE
                .Where(o => o.CLIENT_ID == CLIENT_ID &&
                      (o.HORRAIRE > DateTime.Now.TimeOfDay || 
                       o.HORRAIRE.Hours == 5));

That would make the method behave like you'd like. Though I don't understand, why you want 5:00 returned, even though it is actually smaller than DateTime.Now = 13:00 .

I think your table lacks date information, which makes the logic broken.
