发帖数: 916 | 1 假设有一个table User，primary key is ID(int), one field called Name
given a list of user ID, say HashSet ids
what's the most efficient way to get the list of user?
from u in Users
where ids.Contains(u.ID)
select u
this is the most basic way i can think of. I'm sure there is a better way.
I'm using linq to sql
many thanks! | B*****g
