ASP FSO操作文件(复制文件、重命名文件、删除文件、替换字符串)

ASP FSO操作文件(复制文件、重命名文件、删除文件、替换字符串) FSO的意思是FileSystemObject，即文件系统对象。FSO对象模型包含在Scripting 类型库 (Scrrun.Dll)中，它同时包含了Drive、Folder、File、FileSystemObject和TextStream五个对象，用来操作文件和文件夹十分方便。 (请注意后面的常用函数) FSO文件(File)对象属性 DateCreated 返回该文件夹的创建日期和时间 DateLastAccessed 返回最后一次访问该文件的日期和时间 DateLastModified 返回最后一次修改该文件的日期和时间 Drive 返回该文件所在的驱动器的Drive对象 Name 设定或返回文件的名字 ParentFolder 返回该文件的父文件夹的Folder对象 Path 返回文件的绝对路径，可使用长文件名 ShortName 返回DOS风格的8.3形式的文件名 ShortPath 返回DOS风格的8.3形式的文件绝对路径 Size 返回该文件的大小(字节) Type 如果可能，返回一个文件类型的说明字符串 FSO文件(File)对象方法 FSO文件对象方法 用途 CopyFile 拷贝一个或者多个文件到新路径 CreateTextFile 创建文件并且返回一个TextStream对象 DeleteFile 删除一个文件 OpenTextFile 打开文件并且返回TextStream对象，以便读取或者追加 重命名文件: Function reName(sourceName,destName) dim oFso,oFile set oFso=server.createobject("Scripting.FileSystemObject") set oFile=oFso.getFile(Server.mappath(sourceName)) oFile.Name=destName Set oFso=Nothing Set oFile=Nothing End Function 删除文件: Function FSOdel(fileName) dim fso,f set fso = server.CreateObject("scripting.filesystemobject") f=server.MapPath(fileName) if fso.FileExists(f) then fso.DeleteFile f,true end if set f = nothing set fso = nothing End Function 替换文件中的字符串: Function FSOreplace(fileName,Target,repString) Dim objFSO,objCountFile,FiletempData Set objFSO = Server.CreateObject("Scripting.FileSystemObject") Set objCountFile = objFSO.OpenTextFile(Server.MapPath(fileName),1,True) FiletempData = objCountFile.ReadAll objCountFile.Close FiletempData=Replace(FiletempData,Target,repString) Set objCountFile=objFSO.CreateTextFile(Server.MapPath(fileName),True) objCountFile.Write FiletempData objCountFile.Close Set objCountFile=Nothing Set objFSO = Nothing End Function <%
