如果特定列中的單元格包含數組字符串，如何從Excel文件中刪除行？

Question

我在許多文件夾中都有許多Excel文件，我需要從所有文件中的ex列中刪除行。 B是數組中的單詞：

對於前。 我的壞話清單：

太陽，樹木，大汽車，杯子，...

如果A2列為“太陽是太陽系中心的星星”。 -此行已被刪除。

如果in列中為“ thesunis the ..”-該行已被刪除。 但是不好！

我的問題是：

1. 如何刪除具有數組元素確切詞的行？
2. 如何計算數組元素？
3. 如何在數組元素中轉義單引號（下面的代碼示例）
4. 如何打開文件夾“ C：// folder”中的所有文件，並在運行代碼后保存所有文件？

這是我的代碼：

Sub code()
    Dim MyValue As String
    Dim a As Integer
    '------------------------------------------------------
    ArrayValueToRemove = Array("the sun", "code 'in", "another")
    Range("B:B").Select
    '------------------------------------------------------
    For Each cell In Selection
        MyValue = CStr(cell.Value)
        For a = 0 To 2
            If InStr(1, LCase(MyValue), LCase(ArrayValueToRemove(a))) > 0 Then
                cell.EntireRow.Delete
                Exit For
            End If
        Next
    Next cell
End Sub

Sub deleteBadWordRows()
    Dim currentFile, currentSheet, badWords As Variant, lastRow, i As Integer, baseDirectory As String
    '------------------------------------------------------
    baseDirectory = "c:\folder\"
    badWords = Array("the sun", "code 'in", "another")
    '------------------------------------------------------
    currentFile = Dir(baseDirectory)
    While (currentFile <> "")
        Workbooks.Open baseDirectory + currentFile
            For Each currentSheet In Workbooks(currentFile).Worksheets
                lastRow = currentSheet.Cells(currentSheet.Rows.Count, "B").End(xlUp).Row
                For j = 1 To lastRow
                    For i = 0 To UBound(badWords)
                        If InStr(1, LCase(CStr(currentSheet.Cells(j, "B").Value)), LCase(badWords(i))) > 0 Then
                            currentSheet.Rows(j).Delete
                            j = j - 1
                            lastRow = lastRow - 1
                            Exit For
                        End If
                    Next
                Next
            Next
        Workbooks(currentFile).Save
        Workbooks(currentFile).Close
        currentFile = Dir
    Wend
End Sub

考慮使用帶通配符%的LIKE運算符查詢字符串搜索的SQL解決方案。 Excel for PC可以連接到Jet / ACE SQL引擎（Window .dll文件）並查詢工作簿。 在這里，除了迭代工作簿之外，您避免了嵌套循環。

下面假設所有工作表的結構均為表格形式，列標題均始於A1。 查詢結果將轉儲到新的工作表中，您可以在此之后刪除當前工作表。 確保將占位符替換為實際名稱CurrentWorksheet ， ColumnA ， NewWorksheet ：

Sub DeleteSQL()
    Dim conn As Object, rst As Object
    Dim strConnection As String, strSQL As String
    Dim i As Integer
    Dim wb As Workbook

    Dim dirpath As String: dirpath = "C:\\Folder"
    Dim xlfile As Variant: xlfile = Dir(dirpath & "\*.xls*")

    Do While (xlfile <> "")            
        Set wb = Workbooks.Open(dirpath & "\" & xlfile)
        Set conn = CreateObject("ADODB.Connection")
        Set rst = CreateObject("ADODB.Recordset")

        ' WORKBOOK CONNECTION
        strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" _
                           & "Data Source='" & dirpath & "\" & xlfile & "';" _
                           & "Extended Properties=""Excel 8.0;HDR=YES;"";"            
        ' OPEN DB CONNECTION
        conn.Open strConnection

        ' OPEN RECORDSET
        strSQL = " SELECT * FROM [CurrentWorksheet$]" _
                   & " WHERE [ColumnA] LIKE ""%the sun%"" OR [ColumnA]" _
                   & " LIKE ""%code 'in%"" OR [ColumnA] LIKE ""%another%"""
        rst.Open strSQL, conn

        wb.Sheets.Add(After:=wb.Sheets(wb.Sheets.Count).Name = "NewWorkSheet" 

        ' RESULTSET COLUMNS
        For i = 1 To rst.Fields.Count
            wb.Worksheets("NewWorkSheet").Cells(1, i) = rst.Fields(i - 1).Name
        Next i      

        ' RESULTSET DATA ROWS
        wb.Worksheets("NewWorkSheet").Range("A2").CopyFromRecordset rst

        wb.Close True
        rst.Close: conn.Close
        Set rst = Nothing: Set conn = Nothing

        xlfile = Dir
    Loop
End Sub
