            }
7.           return result;
    }

I get error at line no 6 probably due to wrong coding at line no 4 or due to some missing references. Please help me out. Thank you dear friends.

It is clear that your BoardPost post = dc.BoardPosts... line is returning null so your result.Account = post.Account is failing with post being null.

Whenever you do something to get an object back, always ensure that the object exists before trying to use it.

C#

if( post != null )
   result.Account = post.Account;

As to the syntax of the linq, I don't see anything wrong with it off the top of my head.
