如何将Linq（EF）级联查询的结果转换为泛型集合类型

[寂寞沙洲]

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>();

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 };

你的问题在于 查询时用了匿名类，在ToList()转化时当然出错了

[threenewbee]

List<ContactViewModel> models= contacts.Select(x => new ContactViewModel() { xx = x.xx, yy = x.yy, ... })ToList();

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 }; 这样写报错； ---------------------------- List<ContactViewModel> models= contacts.Select(x => new ContactViewModel() { xx = x.xx, yy = x.yy, ... })ToList(); 可以！！ 谢谢！ 看看大家是否还有其他方法，一会给分！
