Question

I have a table (I am using Entity Model) and filtered that table using LINQ query which is working fine.
Now I want to filter the records on the basis of array of dates. I am not able to implement IN clause on array of dates

filteredList = leadsNewAndScheduled.Where(lead =>  
              (LeadTypeIDs.Contains(lead.TYPE_ID.ToString()) ||
              LeadTypeIDs == string.Empty) &&
              (priorityIDs.Contains(lead.PRIORITY_ID.ToString()) ||
              priorityIDs == string.Empty) &&
              (((lead.EXPIRED_ON <= dateExpiry ||
              Convert.ToDateTime(lead.EXPIRED_ON) == DateTime.Today.Date) &&
              lead.STATUS_ID == (int)Enumerations.LeadStatus.New) ||
              lead.STATUS_ID == (int)Enumerations.LeadStatus.Active) &&
              (lead.START_TIME IN (arrAppointmentDates))
            ).ToList();

I want your help in following

(lead.START_TIME IN (arrAppointmentDates))

Thanks in advance.

Answer 1

I solved this problem while declaring list of dates and then applying contains clause in LINQ query.

example:

//list of dates.
List<DateTime> arrAppointmentDates;

//change in query
arrAppointmentDates.Contains(Convert.ToDateTime(lead.START_TIME).Date)
