$ Mylist =  gwmi Win32_Product |？{$ _。名称-match'office'} |选择名称

推荐答案

尝试一下：

Mylist = Get-WmiObject Win32_Product -Filter"名称如'％office％ ""

如果（

Mylist = Get-WmiObject Win32_Product -Filter "Name like '%office%'" If (

Mylist）{找到了写主机'产品'}
否则{Write-Host'该产品不存在任何信息' }

Mylist) { Write-Host 'Products were found' } Else { Write-Host 'No information exist with this product' }
