Question

I currently have a LINQ query written in one my controllers that I want to return a single blog post (based off a model) with corresponding comments and topics.

This is what I currently have as my query which I used to return a list of all my blog posts for the home page. I added “where p.id == id (which is the parameter taken in by the ActionResult to fetch the correct post.

var post = from p in db.Set<BlogPost>()
                   where p.id == id
                   select new PostViewModel
                              {
                                  Id = p.id,
                                  Title = p.Title,
                                  DateCreated = p.DateCreated,
                                  Content = p.Content,
                                  Topics = p.Topics,
                                  Comments = p.Comments,
                                  CommentCount = p.Comments.Count
                              };

return View(post);

The return currently is sending an IQueryable when I just want it to be a single post. Currently I have a foreach in my razor view which is useless and wrong but it works. How can I change this to do what I want?

You can do:

return View(post.SingleOrDefault());

Or if you want to have an exception in the case list is empty:

return View(post.Single());
