将C＃LINQ转换为VB.NET

我在将C＃中的LINQ查询转换为VB.NET时遇到了一些麻烦。将C＃LINQ转换为VB.NET

C＃：

from row in Users 
group row by row.Password_tx into Passes 
select new {Password = Passes.Key, Total = Passes.Count()}

我试图做到这一点在VB.NET，但我并没有多少运气。我知道Into语法有点不同，但我无法解决这个问题。

VB.NET：

from row in Users _ 
group by pass = row.Password_tx into passes = Group _ 
select with {.passes.Key, .passes.Count()}

这应做到：

From row In Users 
Group By pass = row.Password_tx Into passes = Group 
Select Password = pass, Total = passes.Count

，这里是我用来确认它的工作示例代码：

Public Class Form1 
    Class User 
    Friend Property Password_tx As String 
    Sub New(pwd As String) 
     Password_tx = pwd 
    End Sub 
    End Class 
    Class Users : Inherits Generic.List(Of User) 
    End Class 

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load 
    Dim u As New Users 
    u.Add(New User("abc")) 
    u.Add(New User("bcd")) 
    u.Add(New User("abc")) 

    Dim v = From row In u 
      Group By pass = row.Password_tx Into passes = Group 
      Select Password = pass, Total = passes.Count 
    End Sub 
End Class

也许你可以试试这个。

from row in Users _ 
group by pass = row.Password_tx into passes = Group _ 
select New With {.Password = Passes.Key, _ 
       .Total = Passes.Count()}
