Linq C# to VB.net

本文关键字：net VB to Linq | 更新日期: 2023-09-27 18:09:28

我尝试将以下linq代码从c#转换为vb.net。

var groupedPhotos = from photo in photos
                    orderby photo.TimeStamp
                    group photo by photo.TimeStamp.ToString("y") into photosByMonth
                    select new KeyedList<string, Photo>(photosByMonth);

当我按如下方式转换时，我得到一个错误，说"范围变量名称只能从没有参数的简单或限定名称中推断出来"。我要在哪里换车?

 Dim groupedPhotos = From photo In photos
                     Order By photo.TimeStamp
                     Group photo By photo.TimeStamp.ToString("y") Into Group 
                     Select New KeyedList(Of String, Photo)

Linq C# to VB.net

试试这个:

Dim groupedPhotos = From photo In photos
                    Order By photo.TimeStamp
                    Group photo By Key = photo.TimeStamp.ToString("y") Into g = Group 
                    Select New KeyedList(Of String, Photo)(g)
