Issue with querying database using LINQ query to bring list of DTO - sql

Question

I have a LINQ query in the below format. The problem is that I am passing a list of 100 consumerID in the form of list. I want to query the database and bring result for
all these 100 consumerIds. However the query brings back the result only for the first guy. I am suspecting I am missing something in the where clause. I am sure there are matching results in the database for all these 100 consumerIds.
public ICollection<ConsumerExchangeChangeDto> GetByConsumers(List<int> consumerIDs)
{
EnrollmentReportingModel db = (EnrollmentReportingModel)Context.DbContext;
var results = (from ecew in db.A
join ecewe in db.B on ecew.ID
equals ecewe.ExchangeChangeEnrollmentWindowID into temp
from j in temp.DefaultIfEmpty()
join cecr in db.C on ecew.ConsumerExchangeChangeRequestID equals cecr.ID
join con in db.D on cecr.ConsumerID equals con.ID
where consumerIDs.Contains(con.ID) && !ecew.Deleted
select new E
{
ConsumerID = con.ID,
OrganizationID = con.OrganizationID,
StartDate = ecew.StartDate,
EndDate = ecew.EndDate,
Deleted = ecew.Deleted
}).ToList();
return results;
}
Here is the dto class
public class E : ILzDto
{
public int ConsumerID { get; set; }
public int OrganizationID { get; set; }
public DateTime? StartDate { get; set; }
public DateTime? EndDate { get; set; }
public bool Deleted { get; set; }
}

I think you want Any, not contains:
public ICollection<ConsumerExchangeChangeDto> GetByConsumers(List<int> consumerIDs)
{
EnrollmentReportingModel db = (EnrollmentReportingModel)Context.DbContext;
var results = (from ecew in db.A
join ecewe in db.B on ecew.ID
equals ecewe.ExchangeChangeEnrollmentWindowID into temp
from j in temp.DefaultIfEmpty()
join cecr in db.C on ecew.ConsumerExchangeChangeRequestID equals cecr.ID
where consumerIDs.Any(x => x == cecr.ConsumerID) && !ecew.Deleted
select new E
{
ConsumerID = cecr.ConsumerID,
OrganizationID = con.OrganizationID,
StartDate = ecew.StartDate,
EndDate = ecew.EndDate,
Deleted = false
}).ToList();
return results;
}
