主题：[求助]窗口listbox控件 items 集合 问题

不明白你的意思，如果要用Addrange，就这样

Dim lb As WinForm.ListBox = e.Form.Controls("ListBox1")
Dim sz(10) As   String
Dim lst As new List(of String)
lst.AddRange(lb.Items.ToArray)
'For Each aa As String In lb.items
'lst.Add(aa)
'Next
sz = lst.ToArray
Dim st As String
For i As Integer = 0 To sz.Length-1
    st=st & "  " & sz(i)
Next
Dim kk As WinForm.TextBox = e.Form.Controls("TextBox1")
kk.text =st

 不知道你为什么要这样做。是不是这个目的？

Dim lb As WinForm.ListBox = e.Form.Controls("ListBox1")
Dim kk As WinForm.TextBox = e.Form.Controls("TextBox1")
kk.text = lb.ComboList.Replace("|", " ")

  看了，lb.Items 定义的不是string的集合，所以不能这样用。
