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])?"

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 FileNameIf 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 StringmyTime = InputBox(“请输入当前时间，格式如” & Chr(34) & “201811” & Chr(34))If myTime = “” ThenMsgBox “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 & “” & myTimeEnd IfEnd 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, 1MsgBox (“操作成功！”)End Sub
