我正在尝试使用 FileSystemObject 方法在文本文件中查找特定行，并在该行中替换特定字符串。我对此比较陌生，因为我当前的代码已经用excel打开了文本文件并替换了我需要替换的内容，然后保存并关闭它。这种方式不再是一种选择，因为让 excel 打开文本文件需要很长时间并且会占用文件。

这就是我到目前为止所走的路。

Sub FindLines()

Const ForReading = 1

Set FSO = CreateObject("Scripting.FileSystemObject")

Set objFSO = FSO.OpenTextFile("C:\Users\Carella Home\Desktop\boomboom.txt", ForReading,     False)

Do Until objFSO.AtEndOfStream = True

    go = objFSO.ReadLine

    If InStr(1, go, "ant", vbTextCompare) > 0 Then

        bo = Replace(go, "t", "wow")

    End If

Loop

objFSO.Close

Set objFSO = FSO.OpenTextFile("C:\Users\Carella Home\Desktop\boomboom.txt", 2)

End Sub

我能做的最好的就是打开要写入的文件，但我不知道如何找到该行并将其替换为我需要替换它的行。

如果您愿意帮助/指导我正确的方向，请告诉我是否需要更多信息。我进行了很多搜索，并看到人们提出了其他方法。我需要学习如何以这种方式编辑线条。有人可以帮帮我吗？

提前致谢！

不确定这是否是最有效的方法，但一个想法是使用CreateTextFile的方法FileSystemObject来创建另一个可以写入的文件。

我已经在一个小文件上对此进行了测试，并且似乎按预期工作。

接受答案后修改以避免.ReadLine和.WriteLine循环

Sub FindLines()
'Declare ALL of your variables :)
Const ForReading = 1    '
Const fileToRead As String = "C:\Users\david_zemens\Desktop\test.txt"  ' the path of the file to read
Const fileToWrite As String = "C:\Users\david_zemens\Desktop\test_NEW.txt"  ' the path of a new file
Dim FSO As Object
Dim readFile As Object  'the file you will READ
Dim writeFile As Object 'the file you will CREATE
Dim repLine As Variant   'the array of lines you will WRITE
Dim ln As Variant
Dim l As Long

Set FSO = CreateObject("Scripting.FileSystemObject")
Set readFile = FSO.OpenTextFile(fileToRead, ForReading, False)
Set writeFile = FSO.CreateTextFile(fileToWrite, True, False)

'# Read entire file into an array & close it
repLine = Split(readFile.ReadAll, vbNewLine)
readFile.Close

'# iterate the array and do the replacement line by line
For Each ln In repLine
    ln = IIf(InStr(1, ln, "ant", vbTextCompare) > 0, Replace(ln, "t", "wow"), ln)
    repLine(l) = ln
    l = l + 1
Next

'# Write to the array items to the file
writeFile.Write Join(repLine, vbNewLine)
writeFile.Close

'# clean up
Set readFile = Nothing
Set writeFile = Nothing
Set FSO = Nothing

End Sub

然后，根据您是否要摆脱“原始”文件，您可以执行以下操作：

'# clean up
Set readFile = Nothing
Set writeFile = Nothing
'# Get rid of the "old" file and replace/rename it with only the new one
Kill fileToRead
Name fileToWrite As fileToRead
End Sub

与FileSystemObject

Sub Sample()
    Dim MyData As String, strData() As String

    '~~> Read the file in one go!
    Open "C:\Users\Carella Home\Desktop\boomboom.txt" For Binary As #1
    MyData = Space$(LOF(1))
    Get #1, , MyData
    Close #1
    strData() = Split(MyData, vbCrLf)
End Sub

您所有的文本文件数据现在都在数组中strData只需循环遍历数组并找到要替换的文本并将其写回SAME文件。
