Iqueryable<>合并问题

 var temp = from c in menbers

                      select new

                      {

                          id = c.id,

                          companyname = c.companyname

                      };

            int j = temp.Count();

            var adding = from c in menbers

                       select new

                       {

                           id = 10000,

                           companyname = "火热招租中..."

                       };

请问：temp和adding能够合并在一起用来绑定?具体方法是？
------解决方案--------------------
temp.Concat(adding)
------解决方案--------------------

引用:

temp.Concat(adding)

结果集是在temp里面吗。我怎么datalist绑定temp。还是只有一个数据啊
------解决方案--------------------
temp = temp.Concat(adding); //这样才在temp里面。
------解决方案--------------------

                var temp = (from u in menbers

                            select new

                            {

                                id = u.id,

                                companyname = u.companyname

                            }).Union(

                             from n in menbers
