HI,

how can we use right outer join in c# linq.


here is my code

var selArticles = (from p in eLibObj.Publications
                                      join a in eLibObj.Articles on p.PublicationID equals a.PublicationID

                                      join ar in eLibObj.ArticleReadUnreads.Where(atrxn => atrxn.EmployeeID.Equals(iEmployeeID)) on a.ArticleID equals ar.ArticleID into gj
                                      from newList in gj.DefaultIfEmpty()



                                      where p.Enabled.Equals(true) && a.Published.Equals(1) && a.Enabled.Equals(true)

                                      select new
                                      {
                                          ArticleID = a.ArticleID,
                                          Title = a.Title,
                                          PublicationID = a.PublicationID,
                                          PublicationImage = p.ImageName,
                                          ArticleDate = a.ArticleDate,
                                          PublicationName = p.Name,
                                          ArticleTRXNID = newList.ArticleID == null ? 0 : newList.ArticleID,

                                          ArticleLastReadTime = newList.LastReadTime == null ? new DateTime(1900, 1, 1) : newList.LastReadTime
                                      }).ToList().OrderByDescending(o => o.ArticleLastReadTime).Take(4);

first i get all articles for publication and then want to match all articles with empid and are read and from that want to get only top four records from article. currently what happen that it loads all articles for publication and do left outer join with readunread table if no data match still it gets first 4 records because of the left outer join.
