怎么将Linq（EF）级联查询的结果转换为泛型集合类型

如何将Linq（EF）级联查询的结果转换为泛型集合类型
            var contacts = from c in db.Contact
                                                     join p in db.ContactGroup
                           on c.GroupId equals p.Id
                           select new
                           {
                               c.Id,
                               c.Name,
                               c.Phone,
                               c.Email,
                               c.GroupId,
                               p.GroupName
                           };
如何将contacts转换为泛型集合： IEnumerable<MVCLearning.Models.ContactViewModel>或List<ContactViewModel> 。
下面的方法不行：
                IEnumerable<ContactViewModel> models=contacts.Cast<ContactViewModel>();
下面的代码也不行：
              IEnumerable<ContactViewModel> models= contacts.ToList<ContactViewModel>();
------解决方案--------------------
   var contacts = from c in db.Contact
                                                     join p in db.ContactGroup
                           on c.GroupId equals p.Id
                           select new ContactViewModel
                           {
                               c.Id,
                               c.Name,
                               c.Phone,
                               c.Email,
                               c.GroupId,
                               p.GroupName
                           };
------解决方案--------------------
你的问题在于 查询时用了匿名类，在ToList()转化时当然出错了
------解决方案--------------------
List<ContactViewModel> models= contacts.Select(x => new ContactViewModel() { xx = x.xx, yy = x.yy, ... })ToList();
