如何获取仅包含填充值的属性?
How do I get properties that ONLY have populated values?
例如，如果我跑步
Get-QADUser -Identity "SomeOne" -IncludeAllProperties
输出当然包括..所有属性，包括有值和没有值的属性.我想要一个只有值的属性列表.一般是怎么做的?
the output would of course include.. all properties, including those with and those without values. I want a listing of properties with values only. How is it done generally speaking?
这不仅限于 Quest Cmdlets，我仅以 Get-QADUser 为例.
This wouldn't be restricted to Quest Cmdlets, I only use Get-QADUser as an example.
推荐答案
您可以尝试使用名为 PSObject 的 PowerShell 对象的内置(隐藏)属性，其中包括名为 的属性属性，即父对象上所有属性的列表.
You could try using the built-in (hidden) property of PowerShell objects called PSObject, which includes a property called Properties, i.e. a list of all properties on the parent object.
举个例子也许更容易.以 Get-Process 为例，一个进程可以有许多带有或不带有值的属性(属性).为了只获得具有值的值，您可以这样做:
Maybe easier with an example. Take Get-Process... a process can have many attributes (properties) with or without values. In order to get just the ones with values you do this:
(Get-Process | Select -First 1).PSObject.Properties | ?{$_.Value -ne $null} | FT Name,Value
请注意，我仅将其限制为 Get-Process 返回的第一个进程.然后我们获取在该对象上定义的所有属性，过滤 Value 不为空的地方，然后只显示这些属性的 Name 和 Value.
Note that I limited this to just the first process returned by Get-Process. We then get all the properties defined on that object, filtering where Value is not null and then displaying just the Name and Value for those properties.
