正则表达式和 PowerShell

Question

我有这个 PowerShell 脚本，它会替换配额内的字符串。

$filecontent = "[assembly: AssemblyCopyright(""Copyright © 2014-2015"")]"

$CopyrightRegex = "AssemblyCopyright(.+)"  
$toReplace = '"somethingToReplace"'                    
$result = $filecontent -replace $CopyrightRegex, "AssemblyCopyright($toReplace)" 
Write-Host $result

结果是

[assembly: AssemblyCopyright("somethingToReplace")

但我例外：（最后一个 ] 不见了）

[assembly: AssemblyCopyright("somethingToReplace")]

你能指点我吗，我错过了什么？谢谢。

Answer 1

通过使用 AssemblyCopyright(.+)，您的正则表达式会消耗整个字符串，包括最后的 ]。使用以下内容可能会更好：

$filecontent = '[assembly: AssemblyCopyright("Copyright © 2014-2015")]'
$toReplace = '"something"'
$result = $fileContent -replace "(.*AssemblyCopyright.*)\([^)]+\)(.*)","`($toReplace)`"
write-host $result
