以下代码的excel文件是在固定位置的，
请问各位老师
怎么把代码优化成
Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
类似这样的打开电脑任意位置的excel文件的模式呢

------------------------------------------------------------------------------
Dim Book As New XLS.Book("c:\\test\\订单.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("订单").StopRedraw()
Dim nms1() As String = {"产品","客户","雇员"}
Dim nms2() As String = {"表列名产品","表列名客户","表列名雇员"}
For n As Integer = 1 To Sheet.Rows.Count -1
    Dim r As Row = Tables("订单").AddNew()
    For i As Integer = 0 To sheet.Cols.Count -1
        Dim idx As Integer = array.indexof(nms1, sheet(0,i).Text)
        If idx >= 0 Then
            r(nms2(idx)) = sheet(n, i).Text
        End If
    Next
Next
Tables("订单").ResumeRedraw()
