vb.net 循环配对输出到listbox上 怎么实现

比如listbox1的内容是

www.baidu.com

www.google.com

baidu.com

listbox2的内容是

/robot.txt

/1.zip

/index.php

我想要实现

linstbox1的每行内容都与listbox2的每行内容配对后输出到listbox3

这个过程要怎么实现

就是listbox3输出

www.biadu.com/robot.txt

www.baidu.com/1.zip

www.baidu.com/index.php

www.google.com/1.zip

www.google.com/robot.txt

www.google.com/index.php

代码：

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

        For Each w In ListBox1.Items

            For Each u In ListBox2.Items

                ListBox3.Items.Add(CStr(w) & CStr(u))

            Next

        Next

    End Sub
