asp.net - 如何将 ListItemCollection 转换为 List(of object)

Question

我定义了一个类

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

如何将 ListItemCollection 转换为(MyClass 的)列表？

Answer 1

MyClass 是关键字，VB.NET 中的 float 类型通过 Single 别名 (System.Single) 表示

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

我使用样本数据构建了集合。

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
