int no = 10;
            var duplicate = from m in context.PreferredFeedUserCompaniesFollwers
                            group m by new {m.CompanyID} into grp
                            where grp.Count()>no
                            select new {grp}
我需要获取表中存在的所有comapnyids(一个或多个),其计数与我通过no动态给出的计数匹配。我无法完成任何帮助
