 下面代码能简化吗？

   If  _UserGroup = "校长"  Or _UserGroup = "教导处" Then
        Dim Book As New XLS.Book(ProjectPath & "Attachments\\在籍学生基本信息.xls")
        Dim fl As String  = ProjectPath & "Reports\\在籍学生基本信息.xls"
        Book.Build()
        Book.Save(fl)
        Dim App As New MSExcel.Application
        Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)
        Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
        App.Visible = True
        Ws.PrintPreview
        App.Quit
    Else
        If  _UserGroup = "班主任"  Then
            Dim Book As New XLS.Book(ProjectPath & "Attachments\\基本信息.xls")
            Dim fl As String  = ProjectPath & "Reports\\基本信息.xls"
            Book.Build()
            Book.Save(fl)
            Dim App As New MSExcel.Application
            Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)
            Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
            App.Visible = True
            Ws.PrintPreview
            App.Quit
        End If

End If
