首先感谢大家阅读。其次，我希望 button1 将所有文本从 listbox1 传输到 listbox2。因此，当单击 button1 时，listbox1 中的所有项目都会转移到 listbox2。这是我所拥有的，再次感谢：

ListBox2.Items.Add(ListBox1.SelectedItems)
End Sub

try this:
尝试这个：
ListBox2.Items.Clear() //This is to avoid duplication if button was clicked more than once
For i = 0 To ListBox1.Items.Count - 1
ListBox2.Items.Add(ListBox1.Items(i).ToString)
Next

You traverse on the 1st Listboxselected items and add each item in your 2nd ListBox, like
您遍历第一个Listbox选定的项目并在第二个中添加每个项目ListBox，例如
For Each Item As String In ListBox1.SelectedItems
ListBox2.Items.Add(Item)
Next
