Question

public IEnumerable<Models.Comment> GetUserComments()
{
    return List<Comment>
    {
        new Comment
        {
            CommentFor = "ee",
            DateAdded = DateTime.Now,
            CommentText = "aaaa",
            Location = new Location
            {
                Name = "Location Name",
                Country = new Country
                {
                    Name="Israel"
                },
                State=new State { Name="TelAviv" }
            }
        } 

    };
}

Can you help me correct Linq query for that?

I need to take value from database using Entity Framework 4.
I did like this

         public IEnumerable<Models.Comment> GetUserComments()
    {
         var comment = (from u in context.Comments
                       where u.UserID == userId
                       select new Comment
                       {
                           //Location = context.Locations.FirstOrDefault(x => x.locationid == u.LocationID).name,
                           Location = (from l in context.Locations
                                       where l.LocationID == u.LocationID
                                       select new Location
                                       {
                                           Name = l.Name,
                                           State = (
                                                 from s in context.States
                                                 where (s.StateID == l.StateID)
                                                 select new State { Name  = s.Name }
                                                 ).FirstOrDefault()

                                       }
                                       ).FirstOrDefault(),
                           CommentFor = "bs",
                           DateAdded = u.DateAdded,
                           CommentText = u.CommentText
                       }
                    ).ToList();
                       }

getting error like:

The entity or complex type ‘CGWeb.Models.Repositories.Comment’ cannot be constructed in a LINQ to Entities query.

Please tell me where my mistake i had done

Answer 1

u.Location should be Location.
