我想search一个variables，其中包含从get-childitem获取的文件列表，并将所有匹配项列出到特定的searchstring，但似乎无法得到我想要的结果，我做错了什么？
$TargetFiles = Get-Childitem -OutBuffer 2500 |Where {!$_.PSIsContainer} |Select-Object Name,FullName ForEach ($File in (Select-String -Pattern "*$($CurrentDate.year)-$($CurrentDate.ToString('MM'))-*.gz" -InputObject $TargetFiles -SimpleMatch ) ) { write-host $file } 我已经尝试了许多不同的方法来编写searchstring，包括添加-SimpleMatch并更改searchstring以匹配正则expression式search。
“ $（$ CurrentDate.year） – $（$ CurrentDate.ToString（'MM'）） – .gz”

你只是试图匹配当前月份和年份的文件名？
我没有v1在任何地方testing….但我想不出在v1为什么这不起作用的原因。
IIRC v1仍然有一个pipleline，在哪里对象，让你做简单的名称匹配。
