Linq与团队有计数

Question

如何在linq（vb.net）中编写此查询？

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

Answer 1

像这样：

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

或者，使用方法语法：

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

Answer 2

对于任何想要在vb中执行此操作的人（就像我一样，找不到任何东西）

From c In db.Company 
Select c.Name Group By Name Into Group 
Where Group.Count > 1
