LINQ not working

hi all

I want to combine 2 queries in in one. I have following code and how will i write LINQ to combine it - 

 var List = (from m in resellers
                                select new SelectListItem
                                {
                                    Text = m.Rr,
                                    Value = m.RrId.ToString(),
                                    Selected = m.rId == cId
                                }).OrderBy(t => t.Text).ToList();

                ViewBag.rrs = List;

How will I send or add above LINQ's output to my 2nd LINQ which is given below - 

reportsViewModel.MList = (from m in array //join p in rrs on m equals p.RrId

                                                           select new MModel
                                                           {
                                                               mth = m.Key,
                                                               views = m.Value
                                                           }).OrderBy(t => rrs).ToList();

I tried to join it but it is giving me an error....

Thanks in advance.... any help is appreciated...
