Powershell 中的一切都是对象，因此，它具有方法和属性，正如 LotPings 所评论的，
获取-MsolUser | 获取会员
但这是一个数组，它的属性可能不同，您可以在 foreach 中使用的方法。试试这个（我会用 FileItems 来做，因为我没有那个模块）：
cd $HOME
$files = Get-ChildItem
$files | Get-Member
结果：

但是您并不关心您只想要属性的所有内容，您可以像这样获得它们：
$fileItem = $files[0]
$fileItem | Get-Member -
结果：

Get-Member 输出中的属性之一应该是您正在寻找的。
