Question

i’m trying to learn Entity Framework and I need some help to build my query.
I have a Post class like this :

public class Post
{
    public int PostID {get;set;}
    public string Title {get;set;}
    public string Content {get;set;}
    public PostStatus Status {get;set;}
    public IList<Comment> Comments {get; set;}
}

I also have a Comment class :

public class Comment
{
    public int CommentID {get;set;}
    public string Content {get;set;}
    public CommentStatus Status {get;set;}
}

What I want is to retrieve all Article with Status == PostStatus.Published, including Comment with Status == CommentStatus.Published.

As you understand, I want to display in a blog all published article with their published comment.

I retrieve all published article with all comments, but I only want to get their published comment, not pending ones.

var result = from art in context.Posts.Include("Comments")
             where art.Status == PostStatus.Published
             select art;

Thanks for your help

After some research and using your answers, I found that the good way to go is :

context.Posts.Where(p=> p.InternalStatus == (int)PostStatus.Published).ToList()
    .Select(item =>
                    new Post
                        {
                            PostID = item.PostID,
                            Title = item.Title,
                            Author = item.Author,
                            Content = item.Content,
                            DateCreation = item.DateCreation,
                            Status = item.Status,
                            Comments =
                                item.Comments.Where(
                                    comment => comment.InternalStatus == (int) CommentStatus.Approved).ToList()
                        }).AsQueryable();
