Linq与计数组

我如何在linq（vb.net）中写这个查询？

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

Answer 1

喜欢这个：

 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

对于任何人想在VB中做这个（因为我是，什么都找不到）

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