我的意思是这样的 c3ViIG1zZ19ib3ggKHRleHQp &_ eCh0ZXh0ICwzKzY0LCAiRXhlbXBs 如何使用 nodtepad++

Answer 1

查找：.{40}
替换：[=11=] &_[space]

然后点击"Replace All"。

. 称为通配符，匹配任意字符。
[=13=] 表示您正在用整个匹配（即与它们自己）替换第 40 个字符。在 [=13=] 之后添加 [space]&_[space] 以获得您想要的。

Answer 2

我也在 vb.net 中写了它，这是代码

Sub main()
    Dim aa As String = "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"

    Dim bb As String = aa.Length

    For i As Integer = 40 To bb Step +41
        aa = aa.Insert(i, " &_ ")
    Next
    MsgBox(aa)


End Sub
