VBA研究Excel文件间邮件号码对比筛重

最近业务部门提出一个需求，就是筛查市县分公司上报的邮件号码（比如破损邮件）是否已经报过？具体是什么邮件工具并不关心，只要实现邮件号码筛查就可以了。

功能并不复杂，只是将一个文件中的邮件号码和已有的多个文件中邮件号码比较，记录下比较结果就可以了。已有的文件放在一个文件夹中多个子文件夹中，因此需要遍历这个文件夹下所有文件，以便比较，文件夹内容如下图所示：

遍历所有文件，将文件名放到一个数组中，以便后面一一打开比较。方法是先找出所有文件夹，再找出文件夹下所有文件，代码只针对这种文件夹结构，具体代码如下：

    '原始数据目录
    DirNo = 0
    sFile = Dir(ThisWorkbook.Path & "\\" & pmDir & "\\*", vbDirectory)
    Do While sFile <> ""
        DirNo = DirNo + 1
        arrDir(DirNo) = sFile
        sFile = Dir
    Loop
    
    '找出所有数据文件
    FileNo = 0
    For i = 3 To DirNo
        '查出此文件夹下所有.xls文件（含.xlsx）
        sFile = Dir(ThisWorkbook.Path & "\\" & pmDir & "\\" & arrDir(i) & "\\*.xls")
        Do While sFile <> ""
            FileNo = FileNo + 1
            arrFile(FileNo) = arrDir(i) & "\\" & sFile
            sFile = Dir
        Loop
    Next i
    If FileNo = 0 Then
        MsgBox "数据文件不存在！", vbOKOnly, "iamlaosong"
        Exit Sub
    End If

为了使工具更具通用性，采取一些参数可以设置，工具界面和代码如下：

 

 

Sub get_data()
    
    Dim i, k, k1, k2, MailNo, PmNo, DirNo, FileNo As Integer
    Dim Mail As String, arrDir(20) As String, arrFile(200) As String, sFile As String
    Dim arrData1(), arrData2(), pmDir, pmName, pmRow1, pmCol1, pmCol2
    Dim MaxRow1 As Long, MaxRow2 As Long
 
 
    'On Error GoTo Err
    If Cells(2, 2) = "Y" Or Cells(2, 2) = "y" Then                              '导出出库文件
        Application.ScreenUpdating = True
    Else
        Application.ScreenUpdating = False
    End If
    
    pmDir = Cells(2, 2)
    lineno = [B65536].End(xlUp).Row           '行数
    
    '读取参数
    pmName = Cells(2, 7)
    pmRow1 = Cells(3, 7)
    pmCol1 = Cells(4, 7)
    
    '原始数据目录
    DirNo = 0
    sFile = Dir(ThisWorkbook.Path & "\\" & pmDir & "\\*", vbDirectory)
    Do While sFile <> ""
        DirNo = DirNo + 1
        arrDir(DirNo) = sFile
        sFile = Dir
    Loop
    
    '找出所有数据文件
    FileNo = 0
    For i = 3 To DirNo
        '查出此文件夹下所有.xls文件（含.xlsx）
        sFile = Dir(ThisWorkbook.Path & "\\" & pmDir & "\\" & arrDir(i) & "\\*.xls")
        Do While sFile <> ""
            FileNo = FileNo + 1
            arrFile(FileNo) = arrDir(i) & "\\" & sFile
            sFile = Dir
        Loop
    Next i
    If FileNo = 0 Then
        MsgBox "数据文件不存在！", vbOKOnly, "iamlaosong"
        Exit Sub
    End If
    
    '开始数据处理
    tim1 = Now()
    For unit_num = 5 To lineno                 '文件循环

        datfile = Cells(unit_num, 2)                              '文件名称
        datFullName = ThisWorkbook.Path & "\\" & datfile
        If Dir(datFullName, vbNormal) <> vbNullString Then
            Workbooks.Open Filename:=datFullName        '打开数据文件
            Sheets(pmName).Select
            MaxRow1 = Range(pmCol1 & pmRow1).End(xlDown).Row     '行数
