Linq与组通过计数

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

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);

对于希望在vb中执行此操作的任何人（就像我过去一样，也找不到任何东西）

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

以下解决方案可能会为您提供帮助。

var unmanagedDownloadcountwithfilter = from count in unmanagedDownloadCount.Where(d =>d.downloaddate >= startDate && d.downloaddate <= endDate)
group count by count.unmanagedassetregistryid into grouped
where grouped.Count() > request.Download
select new
{
   UnmanagedAssetRegistryID = grouped.Key,
   Count = grouped.Count()
};
