excel如何代码隐藏指定条件的行

excel表中有一个字段  是否打印  值为是与否

怎么用代码  将是否打印等于否的行  全部显示  是否打印等于是的行  全部隐藏

当前代码如下：有没有办法避免红色部分代码出错并提高效率呢？

Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open("c:\\data\\文书编号.xls")
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
Dim Rg As MSExcel.Range = Ws.UsedRange
Dim ary = rg.value

Dim Book As New XLS.Book("c:\\data\\文书编号.xls") \'定义一个Excel工作簿
Dim Sheet As XLS.Sheet = Book.Sheets(0) \'引用工作簿的第一个工作表
Dim Style As XLS.Style = Book.NewStyle() \'定义新样式
Dim bb2 As Integer=Sheet.Rows.Count
Dim cc2 As Integer=Sheet.cols.Count
output.show(bb2 & "||||" & cc2)
For n As Integer = 2 To bb2
\'禁止显示
    Sheet.Cols(0).Visible= False
    Sheet.Cols(1).Visible= False
    Sheet.Cols(2).Visible= False
    Sheet.Cols(3).Visible= False
    Sheet.Cols(4).Visible= False
    Sheet.Cols(5).Visible= False
    Sheet.Cols(8).Visible= False
    Sheet.Cols(9).Visible= False
    Sheet.Cols(10).Visible= False
    Sheet.Cols(16).Visible= False
\'单元格禁止编辑
        Sheet(n,6).Style.Locked=True
        Sheet(n,7).Style.Locked=True
        Sheet(n,11).Style.Locked=True
        Sheet(n,12).Style.Locked=True
        Sheet(n,13).Style.Locked=True
    For i As Integer = 1 To cc2
        Sheet(n,i).Style.WordWrap=True   \'单元格自动换行\'
        If ary(n,8) = "1" Then
            Sheet.Rows(n).Visible= True   \'当等于1时候  显示当前行\'
        Else
            Sheet.Rows(n).Visible= False  \'当不等于1的时候  隐藏当前行\'
        End If
    Next
\'设定列宽\'
    Sheet.Cols(6).Width = 150
    Sheet.Cols(7).Width = 150
    Sheet.Cols(11).Width = 100
    Sheet.Cols(12).Width = 100
    Sheet.Cols(13).Width = 150
    Sheet.Cols(14).Width = 300
    Sheet.Cols(15).Width = 150
    book.Save("c:\\data\\文书编号1.xls")
Next
app.quit
