for (DateTime i = dtFrom1; i <= dtTo1; i = i.AddDays(1))
{
pdate = new pdate();
pdate.ProgressDate = i.Date;
pdate.prog = 10;
listpdate.Add(pdate);
}
this code is in api which returns listpdate;
Q1) in return stmt should i put order by or will it keep the order in which i have inserted the objects, and finally the api is called in .js so will get every thing in the same order
in which i have entered.
return listpdate.OrderBy(o => o.ProgressDate).ToList();
q2) if i group by on one col in return stmt , then should we use order by or it will keep the objects in listpdate ordered by progressdate in the order i have entered in loop.
so in simple should i put ordeby or not in this case. where i need the data at .js on page order by progress date.
<div> return listpdate.GroupBy(val => DateTime.SpecifyKind(new DateTime(val.ProgressDate.Year, val.ProgressDate.Month,</div> <div> DateTime.DaysInMonth(val.ProgressDate.Year, val.ProgressDate.Month)),DateTimeKind.Utc))</div><div> .Select(grouped => new pdate()</div> <div> {</div> <div> ProgressDate = grouped.Key</div> <div> ,</div> <div> prog = grouped.Sum(Pp => Pp.prog)</div> <div> }).OrderBy(o => o.ProgressDate).ToList();</div> <div> </div>
