Linq with group by having count

Question

how do I write this query in linq (vb.net)?

 select B.Name
 from Company B
 group by B.Name
 having COUNT(1) > 1

Answer 1

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

Answer 2

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);
