最佳解答:

If you want to list the items in a multiline textbox2, embed the following code into a button_click method, you will get AAA, BBB, CCC on separate line. Of course, you can do other things with it the way you like. Note that the item indices are zero-based. Dim crlf As String crlf = Chr(13) Chr(10) Dim i As Integer For i = 1 To ListBox1.Items.Count TextBox2.Text = TextBox2.Text ListBox1.Items.Item(i - 1) crlf Next 2008-05-25 21:10:51 補充： Errata: the + sign had been stripped off by Yahoo TextBox2.Text = TextBox2.Text + ListBox1.Items.Item(i - 1) crlf 2008-05-25 21:12:06 補充： Errata prise 2: TextBox2.Text = TextBox2.Text + ListBox1.Items.Item(i - 1) + crlf
