Entity Framework cast to ObjectSet

I'm pretty new to Entity Framework and I have a question. Is it possible to cast/convert a type var to a strongly typed ObjectSet.

For example I would like to do something like this (this is just an example from my head, not the real code):

var member = from item in memb开发者_Python百科er
                where (age == 30)
                select item;


EF.Member mbr = (EF.Member)member;   // here I would like to cast/convert

Thanks!

Variable of type var is already strongly typed. In your scenario it is IQueryable<Member>. You can't cast it to ObjectSet<Member>. You should be able to cast it to ObjectQuery<Member>.
