PowerShell 带正则表达式参数的Switch语句
示例
该-Regex参数允许switch语句针对条件执行正则表达式匹配。
例：
switch -Regex ('Condition')
{
'Con\D+ion' {'One or more non-digits'}
'Conditio*$' {'Zero or more "o"'}
'C.ndition' {'Any single char.'}
'^C\w+ition$' {'Anchors and one or more word chars.'}
'Test' {'No match'}
}输出：
One or more non-digits Any single char. Anchors and one or more word chars.
