将新特性添加到对象数组中.平行

Question

我想向对象数组添加一个新属性。添加会员无效，请协助

$computers = Get-ADComputer -Filter {(name -like "SMZ-*-DB")} | select -First 30
workflow test-test
{
param([Parameter(mandatory=$true)][string[]]$computers)
$out = @()
foreach -parallel -throttlelimit 20 ($computer in $computers)
{
sequence
{
[bool]$ping = (Test-Connection $computer.name -Quiet -Count 1)
$computer = $computer | Add-Member -NotePropertyName "Ping" -NotePropertyValue $ping            
$Workflow:out += $computer

}
}
return $out  
}
test-test $computers

Answer 1

您可以在powershell 7中执行类似的操作。Get-ADComputer中的ADComputer对象似乎是只读的，因此无法向其中添加成员。

Get-ADComputer -filter 'name -like "a*"' -resultsetsize 3 |
foreach-object -parallel {
$computer = $_
$ping = Test-Connection $computer.name -Quiet -Count 1
[pscustomobject]@{
ADComputer = $computer
Ping = $ping
}
}

ADComputer                      Ping
----------                      ----
CN=A001,DC=stackoverflow,DC=com True
CN=A002,DC=stackoverflow,DC=com True
CN=A003,DC=stackoverflow,DC=com True

Answer 2

如果您需要对象的所有属性，或者以后需要使用该对象，那么将其添加到自定义对象中可能更简单：

sequence
{
[bool]$ping = (Test-Connection $computer.name -Quiet -Count 1)
$newObj = [pscustomobject]@{ADObject = $computer;Ping = $ping}
$Workflow:out += $newObj
}

但通常你只需要获得你需要的属性：

sequence
{
[bool]$ping = (Test-Connection $computer.name -Quiet -Count 1)
$newObj = [pscustomobject]@{ComputerName = $Computer.Name;Ping = $ping}
$Workflow:out += $newObj
}

Answer 3

您要向Microsoft.ActiveDirectory.Management.ADComputer Typename添加的不是数组。

尝试创建PSCustomObject而不是
