 21.读文件最后一行的函数


  function FSOlastline(filename)
  dim fso,f,temparray,tempcnt
  set fso = server.CreateObject("scripting.filesystemobject")
  if not fso.fileExists(server.mappath(filename)) then exit function
  set f = fso.opentextfile(server.mappath(filename),1)
  if not f.AtEndofStream then
  tempcnt = f.readall
  f.close
  set f = nothing
  temparray = split(tempcnt,chr(13)&chr(10))
  FSOlastline = temparray(ubound(temparray))
  end if
  end function


  17.使用FSO读取文件内容的函数


  function FSOFileRead(filename)
  Dim objFSO,objCountFile,FiletempData
  Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
  Set objCountFile = objFSO.OpenTextFile(Server.MapPath(filename),1,True)
  FSOFileRead = objCountFile.ReadAll
  objCountFile.Close
  Set objCountFile=Nothing
  Set objFSO = Nothing
  End Function

  18.使用FSO读取文件某一行的函数


  function FSOlinedit(filename,lineNum)
  if linenum < 1 then exit function
  dim fso,f,temparray,tempcnt
  set fso = server.CreateObject("scripting.filesystemobject")
  if not fso.fileExists(server.mappath(filename)) then exit function
  set f = fso.opentextfile(server.mappath(filename),1)
  if not f.AtEndofStream then
  tempcnt = f.readall
  f.close
  set f = nothing
  temparray = split(tempcnt,chr(13)&chr(10))
  if lineNum>ubound(temparray)+1 then
  exit function
  else
  FSOlinedit = temparray(lineNum-1)
  end if
  end if
  end function

  19.使用FSO写文件某一行的函数
        
  function FSOlinewrite(filename,lineNum,Linecontent)
  if linenum < 1 then exit function
  dim fso,f,temparray,tempCnt
  set fso = server.CreateObject("scripting.filesystemobject")
  if not fso.fileExists(server.mappath(filename)) then exit function
  set f = fso.opentextfile(server.mappath(filename),1)
  if not f.AtEndofStream then
  tempcnt = f.readall
  f.close
  temparray = split(tempcnt,chr(13)&chr(10))
  if lineNum>ubound(temparray)+1 then
  exit function
  else
  temparray(lineNum-1) = lineContent
  end if
  tempcnt = join(temparray,chr(13)&chr(10))
  set f = fso.createtextfile(server.mappath(filename),true)
  f.write tempcnt
  end if
  f.close
  set f = nothing
  end function

  20.使用FSO添加文件新行的函数


  function FSOappline(filename,Linecontent)
  dim fso,f
  set fso = server.CreateObject("scripting.filesystemobject")
  if not fso.fileExists(server.mappath(filename)) then exit function
  set f = fso.opentextfile(server.mappath(filename),8,1)
  f.write chr(13)&chr(10)&Linecontent
  f.close
  set f = nothing
  end function

 使用FSO修改文件特定内容的函数


  function FSOchange(filename,Target,String)
  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,String)
  Set objCountFile=objFSO.CreateTextFile(Server.MapPath(filename),True)
  objCountFile.Write FiletempData
  objCountFile.Close
  Set objCountFile=Nothing
  Set objFSO = Nothing
  End Function
