-replace不会用＆＃34;（）＆＃34;替换字符串。

Question

我试图在PowerShell中替换包含括号的字符串。但是，当我尝试这样做时，它无法正常工作。

知道我哪里出错了吗？我想在PowerShell中用()替换包含-replace的字符串？

$a='Some Text with (round) brackets. This text is long.'
$ch="with (round) brackets."
$b="this text"
$a -replace $ch,$b

输出：

Some Text with (round) brackets. This text is long.

Answer 1

-replace使用正则表达式，因此您必须转义您的regex：

$a='Some Text with (round) brackets. This text is long.'
$ch="with (round) brackets."
$b="this text"
$a -replace [regex]::Escape($ch),$b

<强>输出：

Some Text this text This text is long.

Answer 2

将转义字符\添加到字符串：

$ch="with \(round\) brackets."
$b="this text"
$a -replace $ch,$b

Some Text this text This text is long.

或使用

[Regex]::Escape($ch),$b
