我如何从我本地收藏中存在的DB中获取元素？

Question

here is code

var tempEnities =
                _dc.VKEntities.Where(
                    z => enities.Any(x => x.Name==z.Name && x.Type==z.Type)  ).
                    ToList();

enities is my local collection.

Well ofcourse this code doesnt work because of linq2sql cannt translate Any to sql. Haw can i do it right?

Try this one:

var tempEnities =
                from db in _dc.VKEntities
                join local in enities on new { db.Name, db.Type } 
                equals new {local.Name, local.Type}
                select db;

Some thing like this has been asked quite a few times.
