如何替换这两个特殊字符，被视为一个 -> "( 为 Tr。

(Get-Content $_) -Replace ''''"('''', 'Tr'| Set-Content $_
}

使用-replace，您需要使用\转义(，以便按原样匹配它，因为它是正则表达式的特殊字符之一。请参阅转义字符。
Get-ChildItem "C:\Users\marich\Desktop\richi\*.sql" -Recurse | ForEach-Object {
(Get-Content $_ -Raw) -replace '\"\(\' , 'Tr' | Set-Content $_
}
使用.Replace, 字符串方法会更简单，其中一切都按原样匹配，无需转义：
Get-ChildItem "C:\Users\marich\Desktop\richi\*.sql" -Recurse | ForEach-Object {
(Get-Content $_ -Raw).Replace('\"(' , 'Tr') | Set-Content $_
}
英文:
With -replace you would need to escape the ( with \ to match it literally as it is a regex special character. See Escaping characters.
Get-ChildItem "C:\Users\marich\Desktop\richi\*.sql" -Recurse | ForEach-Object {
(Get-Content $_ -Raw) -replace '"\(', 'Tr' | Set-Content $_
}
It's much easier with .Replace, the String method, where everything is matched literally and no escaping is needed:
Get-ChildItem "C:\Users\marich\Desktop\richi\*.sql" -Recurse | ForEach-Object {
(Get-Content $_ -Raw).Replace('"(', 'Tr') | Set-Content $_
}
