Question

The scenario is, I have simple Post table with just title & story. after posting a new post I want to show the post using my view page.I have write the method to display the post as follows:

  \\Post is the class name & item is the obj to bind it from the view form.
public List<Post> ViewPost(Post item)
    {
        using(var context=new TourBlogEntities1())
        {
            var post= from s in context.Posts
                      where s.PostID=item.PostID //showing error here.
                      select s;

            return post.ToList<Post>();
        }
    }

I’m getting an error saying ‘can’t convert the lambada expression to type string because its not a delegate type’.

Whats need to be done? some more information would also be helpfull, like I have a field name userid in post table, which I want to fill automatically by using the logging info. How can I do that? Thanks.

Answer 1

In your LINQ query replace:

where s.PostID = item.PostID 

with:

where s.PostID == item.PostID 

The where LINQ operator expects a boolean condition and not an assignment.
