VBS 读写文件

创建文本文件

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("C:\FSO\ScriptLog.txt")

检察文件是否存在

Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists("C:\FSO\ScriptLog.txt") Then
    Set objFolder = objFSO.GetFile("C:\FSO\ScriptLog.txt")
Else
    Wscript.Echo "File does not exist."
End If

删除文本文件

Set objFSO = CreateObject("Scripting.FileSystemObject")
objFSO.DeleteFile("C:\FSO\ScriptLog.txt")

重命名文件

Set objFSO = CreateObject("Scripting.FileSystemObject")
objFSO.MoveFile "C:\FSO\ScriptLog.txt" , "C:\FSO\BackupLog.txt"

文本操作

读取全部内容

Const ForReading = 1

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\Scripts\Test.txt", ForReading)

strContents = objFile.ReadAll
objFile.Close

一行行的读取文本文件内容

Const ForReading = 1

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTextFile = objFSO.OpenTextFile ("c:\scripts\servers.txt", ForReading)

Do Until objTextFile.AtEndOfStream
    strComputer = objTextFile.ReadLine
    Wscript.Echo strComputer
Loop

objTextFile.Close

追加文本文件一行内容

Const ForAppending = 8
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTextFile = objFSO.OpenTextFile ("C:\Scripts\Service_Status.txt", ForAppending, True)
objTextFile.WriteLine("追加的内容")
objTextFile.Close

有用的几个函数：

替换：将Jim替换成James。

strNewText = Replace(strText, "Jim ", "James ")

用逗号分隔字符串：

arrpath=split(strDN,",")
wscript.echo arrpath(0)

几个实例：

读取文本文件指定的行内容（读第四行内容存到strLine变量中）

Const ForReading = 1

Set objFSO = CreateObject("Scripting.FileSystemObject") Set objTextFile = objFSO.OpenTextFile

("mylogfile.log", ForReading)

For i = 1 to 3 objTextFile.ReadLine Next

strLine = objTextFile.ReadLine Wscript.Echo strLine

objTextFile.Close
