Question

我有一个包含许多列的大型电子表格。很多这些列都不会被使用，需要删除。当我在VBA中编写过程时，我编写了一个删除除列出的列之外的所有列的过程。我可以在VB.net中做同样的事吗？

我研究了网络，看了如何使用A列，B列等来做到这一点。我无法这样做，因为这是一个导出文件，每次都会更改列顺序。唯一的常量是列名称，不会更改。

这是我在VBA中写的内容。

    Sub prepareExports()

'This is Step 3 when the frmDataImportSplash is activated.

'This procedure deletes the first 7 rows of the sheets and
'deletes all columns that won't be used during the process.

Application.ScreenUpdating = False


For Each WS In Sheets(Array("byEmployee", "byPosition"))

With WS



    k = .UsedRange.Columns.Count

    'For the referenced sheets above delete all columns except for the ones listed below.  These columns the reference column for the entire workbook.

    For i = k To 1 Step -1
        Select Case LCase$(.UsedRange.Cells(1, i))
           Case "#ees", "annu. base at target", "annualized fte base pay", "annu. base mkt - 10th", "annu. base mkt - 25th", "annu. base mkt - 50th", "annu. base mkt - 75th", _
            "annu. base mkt - 90th", "annual base max", "annual base mid", "annual base min", "annualized base max", "annualized base mid", "annualized base min", _
            "annualized compa-ratio", "annualized range penetration", "employee dept", "employee id", "employee name", _
            "functional area", "hourly at target", "hourly base max", "hourly base mid", "hourly base min", "hourly compa-ratio", "hourly mkt - 10th", _
            "hourly mkt - 25th", "hourly mkt - 50th", "hourly mkt - 75th", "hourly mkt - 90th", "hourly range penetration", "hourly rate", "job code", _
            "market percentile of annu. base", "market percentile of hourly rate", "market percentile of salary mid", _
            "mid to annu. target delta | %", "mid to hourly target delta | %", "internal title", "salary", "salary at target", "salary compa - ratio", _
            "salary range penetration", "target market-ratio", "market percentile of annu. base", "Annu. Base Delta $ | %", "exemption", _
            "salary mkt - 10th", "salary mkt - 25th", "salary mkt - 50th", "salary mkt - 75th", "salary mkt - 90th", "salary at target", "mid to salaried target delta | %", _
            "tcc mkt - 10th", "tcc mkt - 25th", "tcc mkt - 50th", "tcc mkt - 75th", "tcc mkt - 90th", "grade"


                    'do nothing
            Case Else
                .UsedRange.Columns(i).Delete

                Application.ScreenUpdating = True

        End Select
    Next i
  End With
Next WS

End Sub

我能够弄清楚如何做到这一点：

Dim xlWB As Excel.Workbook = CType(Globals.ThisWorkbook.Application.ActiveWorkbook, Excel.Workbook)
Dim xlWSPosition As Excel.Worksheet = CType(CType(xlWB.Sheets("byPosition"), Excel.Worksheet), Excel.Worksheet)
Dim xlWSEmployee As Excel.Worksheet = CType(CType(xlWB.Sheets("byEmployee"), Excel.Worksheet), Excel.Worksheet)      

Dim xlSheets As Object
        Dim xlSheetsArray(0 To 1) As Excel.Worksheet
        Dim k As Long
        Dim i As Long

        xlSheetsArray(0) = xlWSPosition
        xlSheetsArray(1) = xlWSEmployee


        For Each xlSheets In xlSheetsArray

            With xlSheets


                'With the above sheets, replace the first 7 rows. They only contain Payscale generic information so we can get rid of it.
                .Rows("1:7").Delete(Excel.XlDirection.xlUp)


                k = .UsedRange.Columns.Count

                'For the referenced sheets above delete all columns except for the ones liste below.  These columns the reference column for the entire workbook.

                For i = k To 1 Step -1
                    Select Case LCase(.UsedRange.Cells(1, i).Value)

                        'Keep these columns
                        Case "#ees", "annu. base at target", "annualized fte base pay", "annu. base mkt - 10th", "annu. base mkt - 25th", "annu. base mkt - 50th", "annu. base mkt - 75th", _
                         "annu. base mkt - 90th", "annual base max", "annual base mid", "annual base min", "annualized base max", "annualized base mid", "annualized base min", _
                         "annualized compa-ratio", "annualized range penetration", "employee dept", "employee id", "employee name", _
                         "functional area", "hourly at target", "hourly base max", "hourly base mid", "hourly base min", "hourly compa-ratio", "hourly mkt - 10th", _
                         "hourly mkt - 25th", "hourly mkt - 50th", "hourly mkt - 75th", "hourly mkt - 90th", "hourly range penetration", "hourly rate", "job code", _
                         "market percentile of annu. base", "market percentile of hourly rate", "market percentile of salary mid", _
                         "mid to annu. target delta | %", "mid to hourly target delta | %", "internal title", "salary", "salary at target", "salary compa - ratio", _
                         "salary range penetration", "target market-ratio", "market percentile of annu. base", "Annu. Base Delta $ | %", "exemption", _
                         "salary mkt - 10th", "salary mkt - 25th", "salary mkt - 50th", "salary mkt - 75th", "salary mkt - 90th", "salary at target", "mid to salaried target delta | %", _
                         "tcc mkt - 10th", "tcc mkt - 25th", "tcc mkt - 50th", "tcc mkt - 75th", "tcc mkt - 90th", "grade"

                        Case Else

                            'Delete all others not listed above
                            .UsedRange.Columns(i).Delete()

                    End Select
                Next i

            End With

        Next xlSheets
