原文:
Sometimes you may want to tag results returned by a cmdlet with some extra information, such as a reference to some PC name or a timestamp. You can use Add-Member to tag a note property to the result.
This line gets all services and adds two new columns: the PC name, and the date and time the results were returned:
$result = Get-Service | Add-Member NoteProperty Computer $env:computername -pass | Add-Member NoteProperty Timestamp (Get-Date) -pass
$result | Select-Object Status, Name, Computer, Time*
Note that you will only see the new columns if you explicitly ask Select-Object to show them.
翻译：
有时需要在cmdlet命令的返回结果中加一些附加的信息，比如机器名或者时间戳。可以在返回的结果中使用Add-Member来标记一个笔记属性。
下面的命令返回所有的服务并且加了附加的两个列：机器名和时间戳：
$result = Get-Service | Add-Member NoteProperty Computer $env:computername -pass | Add-Member NoteProperty Timestamp (Get-Date) -pass
$result | Select-Object Status, Name, Computer, Time*
如果只想显示这两个新增列的话只要通过Select-Object明确指定就可以了。
笔记：
Add-Member NoteProperty 列名 值 -pass
