PowerShell 替换字符串中的数字 [英] PowerShell Replace number in string

问题描述

我不是这样的 regex 专家，坦率地说，我尽量避免它.

I'm not such a regex expert and frankly I'm trying to avoid it whenever I can.

我想创建一个新的 $String，其中字符串中的数字用 +1 更新.该数字可以是一位或两位数字，并且始终位于 2 个括号之间.

I would like to create a new $String where the number within the string is updated with +1. This number can be one or two digits and will always be between 2 brackets.

来自:

$String = "\\Server\c$\share_1\share2_\Taget2[1] - 2014-07-29.log"

致:

$String = "\\Server\c$\share_1\share2_\Taget2[2] - 2014-07-29.log"

感谢您的帮助.

推荐答案

如果你想避免正则表达式:

If you want to avoid the regex:

$String = "\\Server\c$\share_1\share2_\Taget2[1] - 2014-07-29.log"
$parts = $string.Split('[]')
$Newstring = '{0}[{1}]{2}' -f $parts[0],(1 + $parts[1]),$parts[2]
$Newstring
\\Server\c$\share_1\share2_\Taget2[2] - 2014-07-29.log
