VBA遍歷文件夾下文件文件實用源碼

‘批量遍歷文件夾下某類文件，並統計編號
Sub OpenAndClose()
    Dim MyFile As String
    Dim s As String
    Dim count As Integer
    MyFile = Dir("d:\data\" & "*.csv")
    '讀入文件夾中第一個.xlsx文件
    count = count + 1       '記錄文件的個數
    s = s & count & "、" & MyFile
    Do While MyFile <> " "
        MyFile = Dir        '第二次讀入的時候不用寫參數
        If MyFile = "" Then
            Exit Do         '當myfile爲空時候說明已經遍歷完了，推出do,不然要從新運行一遍
        End If
        count = count + 1
        If count Mod 2 <> 1 Then
            s = s & vbTab & count & "、" & MyFile
        Else
            s = s & vbCrLf & count & "、" & MyFile
        End If
    Loop
   Debug.Print s
End Sub

‘遍歷每一個文件，而且修改文件，先將文件的名字存在數組中，而後經過數組遍歷打開每一個文件，修改，再關閉文件~


Sub OpenCloseArray()
    Dim MyFile As String
    Dim Arr(100) As String
    Dim count As Integer
    MyFile = Dir("D:\data\data2\" & "*.xlsx")
    count = count + 1
    Arr(count) = MyFile
    
    Do While MyFile <> ""
        MyFile = Dir
        If MyFile = "" Then
            Exit Do
        End If
        count = count + 1
        Arr(count) = MyFile         '將文件的名字存在數組中
    Loop
    
    For i = 1 To count
        Workbooks.Open Filename:="d:\data\data2\" & Arr(i)  '循環打開Excel文件
            Sheet1.Cells(2, 2) = "alex_bn_lee"             '修改打開文件的內容
        ActiveWorkbook.Close savechanges = True     '關閉打開的文件
    Next
‘要是想要修改每一個工做簿的內容能夠這樣遍歷一下，顯示將文件夾中的工做簿的名字存到’一個字符串數組中，而後在用For...Next語句遍歷

‘遍歷某個文件夾中的全部文件（*.*)
’注意：遍歷的時候，順序徹底是按照文件名的順序排的，而不是按照文件夾中文件的順序~
