主题：快捷菜单中删除多行

对快捷菜单中的行删除作了以下修改，希望删除多行该怎么修改？

For i As Integer = CurrentTable.TopPosition To CurrentTable.BottomPosition
    Dim r As Row = CurrentTable.Current
    Dim msg As String = "D#" & CurrentTable.DataTable.name & "#" & r("_Identify")
    r.Delete()
    CurrentTable.DataTable.Save()
    For Each bd As QQBuddy In QQClient.Buddies
        If bd.Online Then
            QQClient.Send(bd.name, msg)
        End If
    Next
Next
