I am wondering if there is an better option to escape regex characters in powershell, I know C# has Regex.Escape, but I'm not sure if powershell has its own method...
我想知道在powershell中是否有更好的选项来转义regex字符，我知道c#有regex。Escape，但是我不确定powershell是否有自己的方法……
This is what I am doing at the moment:
这就是我现在正在做的事情:
$escapedStr = $regexStr -replace "\+","\+" -replace "\[","\[" -replace "\]","\]" -replace "\(","\(" -replace "\)","\)"

PowerShell can call the exact same method:
PowerShell可以调用完全相同的方法:
[Regex]::Escape($regexStr)
But you could even improve your replacement by using just a single regex replace:
但是您甚至可以通过使用一个regex替换来改进您的替换:
$regexStr -replace '[[+*?()\\.]','\$&'
However, I probably still missed a few metacharacters from that character class, so just use the [regex]::Escape method.
但是，我可能仍然忽略了字符类中的一些元字符，因此只需使用[regex]: Escape方法。
