我一直在研究PowerShell函数来查询WSUS并返回计算机名，更新组，LastSyncTime和所需/失败的更新。
该函数输出对象
typename: Microsoft.UpdateServices.Internal.BaseApi.ComputerTarget
我为这个现有对象添加了自定义属性，只想设置输出中显示的对象。为了设置它，我使用了这段代码：
#Creating my object:
[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer("mywsusserver.domain.local",$False)
$results = $wsus.SearchComputerTargets("search_string")
#add Custom Members
$results | Add-Member -MemberType AliasProperty -Name ComputerName -Value FullDomainName
$results | Add-Member -NotePropertyName "Groups" -NotePropertyValue ($results.GetComputerTargetGroups() | where {$_.name -ne 'All Computers'}).name
$results | Add-Member -NotePropertyName "NeededUpdates" -NotePropertyValue ($objupdateinfo.downloadedcount + $objupdateinfo.notinstalledcount)
$results | Add-Member -NotePropertyName "FailedUpdates" -NotePropertyValue $objupdateinfo.failedcount
#set the default display properties for my object
$defaultDisplayset = 'ComputerName','Groups','IPAddress','LastSyncTime','NeededUpdates','FailedUpdates'
$defaultDisplayPropertySet = New-Object System.Management.Automation.PSPropertySet('DefaultDisplayPropertySet',[string[]]$defaultDisplaySet)
$PSStandardMembers = [System.Management.Automation.PSMemberInfo[]]@($defaultDisplayPropertySet)
$results | Add-Member MemberSet PSStandardMembers $PSStandardMembers
显示属性信息：this article。
所以当我显示这个代码块的输出时，我得到这样的东西：
PS C:\> $results ComputerName : Servername1 Groups : Third Week IPAddress : 192.168.1.100 LastSyncTime : 9/13/2017 2:19:51 AM NeededUpdates : 15 FailedUpdates : 0 ComputerName : Servername2 Groups : Customer - Third Week IPAddress : 192.168.100.73 LastSyncTime : 9/13/2017 2:44:34 AM NeededUpdates : 7 FailedUpdates : 0 ComputerName : Servername3 Groups : Third Week IPAddress : 192.168.200.233 LastSyncTime : 9/13/2017 2:09:23 AM NeededUpdates : 6 FailedUpdates : 0
我想默认显示的是：
ComputerName Groups IPAddress LastSyncTime NeededUpdates FailedUpdates ------------ ------ --------- ------------ ------------- ------------- Servername1 Third Week 192.168.1.100 9/13/2017 2:19:51 AM 15 0 Servername2 Third Week 192.168.100.73 9/13/2017 2:44:34 AM 7 0 Servername3 Third Week 192.168.200.233 9/13/2017 2:09:23 AM 6 0
但我发现实现它的唯一方法是使用：
$results | Format-Table -AutoSize
我已经探索过this article，我只想让这个对象的输出成为一个表，而不必使用Format-Table来实现它。
