I was wondering if anyone had a better idea how to do this. atm returning IQueryable<Member> as ObjectQuery<Member> seems dirty to me.
namespace Falcon.Business.Repositories

public class MemberRepository : LinqRepository<Member>, IMemberRepository

public Member Fetch(MemberCriteria criteria)
{
ObjectQuery<Member> query = base.CreateQuery();
query = this.AddRelations(query);
query = this.AddCriteria(query, criteria);
query = this.AddCriteriaOrder(query, criteria);
return query.FirstOrDefault();
}
public IPagerService<Member> FetchAll(MemberCriteria criteria)
{
int page = (criteria.Page.HasValue) ? criteria.Page.Value : 1;
int limit = criteria.Limit;
int start = (page * limit) - limit;
int total = this.Count(criteria);
ObjectQuery<Member> query = base.CreateQuery();
query = this.AddRelations(query);
query = this.AddCriteria(query, criteria);
query = this.AddCriteriaOrder(query, criteria);
return new PagerService<Member>(query.Skip(start).Take(limit).ToList(), page, limit, total);
}
public int Count(MemberCriteria criteria)
{
ObjectQuery<Member> query = base.CreateQuery();
query = this.AddCriteria(query, criteria);
return query.Count();
}
public ObjectQuery<Member> AddCriteria(IQueryable<Member> query, MemberCriteria criteria)
{
if (criteria.Title.HasValue())
{
query = query.Where(q => q.Title == criteria.Title);
}
if (criteria.TitleUrl.HasValue())
{
query = query.Where(q => q.TitleUrl == criteria.TitleUrl);

{
query = query.Where(q => q.EmailAddress == criteria.EmailAddress);
}
if (criteria.HostAddress.HasValue())
{
query = query.Where(q => q.HostAddress == criteria.HostAddress);
}
query = query.Where(q => q.Status == criteria.Status);
return query as ObjectQuery<Member>;
}
public ObjectQuery<Member> AddCriteriaOrder(IQueryable<Member> query, MemberCriteria criteria)
{
if (criteria.Sort == SortMember.ID)
{

}
else
{

? query.OrderBy(q => q.Created)

}
return query as ObjectQuery<Member>;
}
private ObjectQuery<Member> AddRelations(ObjectQuery<Member> query)
{
query = query.Include(x => x.Country);

return query;
