在VB中遍历文件并用正则表达式完成复制及vb实现重命名、拷贝文件夹的方法

先看下在VB中遍历文件并用正则表达式完成复制功能

将"E:\my\汇报\成绩"路径下源文件中的“1项目”，“一项目”等文件复制到目标文件下。以下为实现方式。

Private Sub Option1_Click()
Dim myStr As String

'通过在单元格中输入项目序号,目前采用的InputBox方式指定的，也可通过此方式。二者取其一。
'myStr = Sheets(“Sheet1”).Range(“D21”).Text
 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 '通过InputBox输入项目序号Start
 ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 myStr = InputBox("请输入项目序号，序号要为阿拉伯数字。格式一定要正确！格式如" & Chr(34) & "2项目" & Chr(34))
 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 '通过InputBox输入项目序号End
 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 Dim endNum As Integer 'MID函数截取结束位数
 endNum = InStrRev(myStr, "项")
 myStr = Mid(myStr, 1, endNum - 1)
 'MsgBox myStr
 Dim CChinesStr As String
 CChineseStr = CChinese(myStr) '将阿拉伯数字转为汉字
 'MsgBox CChineseStr
 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 '遍历路径下的文件Start
 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 Dim fso As Object
 Dim folder As Object
 Dim subfolder As Object
 Dim file As Object
 Dim fileNameArray As String
 Dim basePath As String
 basePath = "E:\my\汇报\成绩"
 Set fso = CreateObject("scripting.filesystemobject") '创建FSO对象
 Set folder = fso.getfolder(basePath & "\源文件")
 For Each file In folder.Files '遍历根文件夹下的文件
 'fileNameArray = fileNameArray & file & "|"
  Dim mRegExp As Object '正则表达式对象
  Dim mMatches As Object '匹配字符串集合对象
  Dim mMatch As Object '匹配字符串
  Set mRegExp = CreateObject("Vbscript.Regexp")
  With mRegExp
   .Global = True    'True表示匹配所有, False表示仅匹配第一个符合项
   .IgnoreCase = True    'True表示不区分大小写, False表示区分大小写
   '.Pattern = "([0-9])?[.]([0-9])+|([0-9])+" '匹配字符模式
   '.Pattern = "((([0-9]+)?)|(([一二三四五六七八九十]+)?))项目(([一二三四五六七八九十]+)?)|([0-9])?" '匹配字符模式
   '.Pattern = "(项目(二百三十四)+)|(((234)?|(二百三十四)?)项目(234)?)" '匹配字符模式
   '.Pattern = "(((" & "+)?)|(([一二三四五六七八九十]+)?))项目(([一二三四五六七八九十]+)?)|([0-9])?" '匹配字符模式
   .Pattern = "(项目(" & CChineseStr & ")+)|(((" & myStr & ")?|(" & CChineseStr & ")?)项目(" & myStr & ")?)" '匹配字符模式

   'Set mMatches = .Execute(Sheets("上报").Range("D21").Text) '执行正则查找，返回所有匹配结果的集合，若未找到，则为空

   Set mMatches = .Execute(file) '执行正则查找，返回所有匹配结果的集合，若未找到，则为空
   For Each mMatch In mMatches
   'SumValueInText = SumValueInText + CDbl(mMatch.Value)
   'SumValueInText = SumValueInText & mMatch.Value
   If mMatch.Value <> "" Then
   'fileNameArray = fileNameArray & mMatch.Value & "_"
   fso.copyfile basePath & "\源文件\" & mMatch.Value & ".*", basePath & "\目标文件" & myStr '复制操作
   End If

  Next

  End With
  'MsgBox fileNameArray

  Set mRegExp = Nothing
  Set mMatches = Nothing

 Next
 Set fso = Nothing
 Set folder = Nothing
 ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 '遍历路径下的文件End
 ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
 MsgBox "操作完成"

End Sub
'将阿拉伯数字转为汉字
Private Function CChinese(StrEng As String) As String
'验证数据
If Not IsNumeric(StrEng) Then
If Trim(StrEng) <> “” Then MsgBox “无效的数字”
CChinese = “”
Exit Function
End If
'定义变量
Dim intLen As Integer, intCounter As Integer
Dim strCh As String, strTempCh As String
Dim strSeqCh1 As String, strSeqCh2 As String
Dim strEng2Ch As String
'strEng2Ch = “零壹贰叁肆伍陆柒捌玖”
strEng2Ch = “零一二三四五六七八九十”
'strSeqCh1 = " 拾佰仟 拾佰仟 拾佰仟 拾佰仟"
strSeqCh1 = " 十百千 十百千 十百千 十百千"
strSeqCh2 = " 万亿兆"
'转换为表示数值的字符串
StrEng = CStr(CDec(StrEng))
'记录数字的长度
intLen = Len(StrEng)
'转换为汉字
For intCounter = 1 To intLen
'返回数字对应的汉字
strTempCh = Mid(strEng2Ch, Mid(StrEng, intCounter, 1) + 1, 1)
'若某位是零
If strTempCh = “零” And intLen <> 1 Then
'若后一个也是零，或零出现在倒数第1、5、9、13等位，则不显示汉字“零”
If Mid(StrEng, intCounter + 1, 1) = “0” Or (intLen - intCounter + 1) Mod 4 = 1 Then strTempCh = “”
Else
strTempCh = strTempCh & Trim(Mid(strSeqCh1, intLen - intCounter + 1, 1))
End If
'对于出现在倒数第1、5、9、13等位的数字
If (intLen - intCounter + 1) Mod 4 = 1 Then

'添加位" 万亿兆"
strTempCh = strTempCh & Trim(Mid(strSeqCh2, (intLen - intCounter) \ 4 + 1, 1))
End If
'组成汉字表达式
strCh = strCh & Trim(strTempCh)
Next
CChinese = strCh
End Function

补充：下面看下用VB实现重命名、拷贝文件夹及文件

Private Sub commandButton1_Click()

'声明文件夹名和路径
Dim FileName, Path As String, EmptySheet As String
'Path = “D:\上报”
Path = InputBox(“请输入” & Chr(34) & “成绩” & Chr(34) & “文件夹的路径，格式如” & Chr(34) & “D:\成绩” & Chr(34))
FileName = Path & “\上学期”
EmptySheet = Path & “\学期初始化”
'MsgBox FileName
If Dir(FileName, vbDirectory) <> “” Then
'MsgBox “文件夹存在”
'获取系统当前时间
'Dim dd As Date
'dd = Now
'MsgBox Format(dd, “yyyymm”)
Dim myTime As String
myTime = InputBox(“请输入当前时间，格式如” & Chr(34) & “201811” & Chr(34))
If myTime = “” Then
MsgBox “当前时间不能为空！否则不能重命名当期文件夹”
Else:
Name FileName As Path & “” & myTime
End If
End If
'判断文件夹是否存在
If Dir(FileName, vbDirectory) = “” Then
'创建文件夹
MkDir (FileName)
'MsgBox (“创建完毕”)
Else: MsgBox (“文件夹已在”)
End If
'复制空表到当期
Set Fso = CreateObject(“Scripting.FileSystemObject”)
'拷贝文件夹
Fso.copyfolder EmptySheet, FileName
'Fso.copyfile EmptySheet&“c:*.*”, “d:” '拷贝文件
'FileSystemObject.copyfolder EmptySheet, FileName, 1
MsgBox (“操作成功！”)
End Sub
