调用toolstrip里面的代码段的疑问

如下代码，怎么调用case后的0、1、2里面的代码段呢，先谢过。

Private Sub ToolStrip1_ItemClicked(sender As System.Object, e As System.Windows.Forms.ToolStripItemClickedEventArgs) Handles ToolStrip1.ItemClicked
        Select Case ToolStrip1.Items.IndexOf(e.ClickedItem)
            Case 0
                代码段
            Case 1
            Case 2
            .
            .
            .
    Case n
         End Select
End Sub
