Linq与组通过计数

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 

或者使用方法的语法：

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

Answer 2

对于任何人要做到这一点在VB（因为我是，但没有找到任何东西）

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