Sorting a list of <Object> with VB and LINQ
提问by WhiskerBiscuit
I'm trying out some LINQ expressions and can't get them to work with the List class. Basically I want to be able to sort a list of custom objects by property type, however the C# LINQ syntax is KILLING me and I can't figure out how to convert it to VB
我正在尝试一些 LINQ 表达式，但无法让它们与 List 类一起使用。基本上我希望能够按属性类型对自定义对象列表进行排序，但是 C# LINQ 语法正在杀死我，我无法弄清楚如何将其转换为 VB
Class Foo
Sub New(Name As String, Position As Integer)
Me.Name = Name
Me.Position = Position
End Sub
Public Name As String
Public Position As Integer
End Class
Sub Main()
Dim l As New List(Of Foo)
l.Add(New Foo("C", 3))
l.Add(New Foo("B", 2))
l.Add(New Foo("A", 1))
Dim asc = ..... (sort l by position asecnding)
Dim desc = ..... (sort l by position descending)
End Sub

Dim asc = From f In l Order By f.Position
Dim desc = From f In l Order By f.Position Descending

I used c# to VB converter..
我用 c# 到 VB 转换器..
Dim sortedasc = l.OrderBy(Function(k) k.Position)
Dim sorteddesc = l.OrderByDescending(Function(k) k.Position)
this should work..
这应该工作..
