Linq with group by having count
Like this:
from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key
Or, using the method syntax:
Company
.GroupBy(c => c.Name)
.Where(grp => grp.Count() > 1)
.Select(grp => grp.Key);
For anyone looking to do this in vb (as I was and couldn't find anything)
From c In db.Company
Select c.Name Group By Name Into Group
Where Group.Count > 1
