如何轉換ListItemCollection列出

Question

我定義了諸如

Public Class MyClass 
Public Type1 As Integer 
Public Type2 As float 
End Class 

一類我怎麼能轉換ListItemCollection到（MyClass的的）的列表（對象）？

Answer 1

MyClass的是在VB.NET關鍵字和float型經由Single別名（System.Single）

Public Class Item 
    Public Type1 As Integer 
    Public Type2 As Single 
End Class 

我已經構建表達收集與樣品數據。

Dim cl As New ListItemCollection 
cl.Add(New ListItem("1", "1.2")) 
cl.Add(New ListItem("2", "2.3")) 
cl.Add(New ListItem("3", "3.4")) 

Dim lst = From ele In cl Select New _ 
        Item With 
        { 
         .Type1 = Integer.Parse(ele.Text), 
         .Type2 = Single.Parse(ele.Value) 
        } 

For Each ele As Item In lst 
    Response.Write("<br/> " & ele.Type1 & " " & ele.Type2) 
Next 

Answer 2

Dim x As New List(of [MyClass]) 

For Each y as [MyClass] in ListItemCollectionInstance.Items 

    if (y.Selected) 
     x.Add(y) 
Next y 

使用LINQ：

Dim selectedItems As List(Of [MyClass]) = ListItemCollectionInstance.Items.Cast(Of [MyClass])().Where(Function(itm) itm.Selected = True).ToList()
