我的目标是创建一个具有两个离散变量（fooName和fooUrl）和一个fooChildren列表的自定义数据对象，每个列表项都具有两个离散变量变量{{ 1}}和childAge。
目前，我有这个：
childName产生以下内容。到目前为止一切顺利
$fooCollection = [PSCustomObject] @{fooName=""; fooUrl=""; fooChildrenList=@()}
$fooCollection.fooName = "foo-a-rama"
$fooCollection.fooUrl = "https://1.2.3.4"
$fooChild = New-Object -TypeName PSobject
$fooChild | Add-Member -Name childAge -MemberType NoteProperty -Value 6
$fooChild | Add-Member -Name childName -MemberType NoteProperty -Value "Betsy"
$fooCollection.fooChildrenList += $fooChild
$fooChild = New-Object -TypeName PSobject
$fooChild | Add-Member -Name childAge -MemberType NoteProperty -Value 10
$fooChild | Add-Member -Name childName -MemberType NoteProperty -Value "Rolf"
$fooCollection.fooChildrenList += $fooChild
cls
$fooCollection.fooName
$fooCollection.fooUrl
foreach ($fooChild in $fooCollection.fooChildrenList)
{
(" " + $fooChild.childName + " " + $fooChild.childAge)
}
问题：我不喜欢使用foo-a-rama
https://1.2.3.4
Betsy 6
Rolf 10
，因为据我了解，使用+=会创建+=的副本（无论如何每次执行$fooCollection.fooChildrenList时都会显示它所在的状态。
因此，我不想将+=实现为fooChildrenList，而是想将@()实现为fooChildrenList，以便可以根据需要添加每一行。我已经尝试了多种方式在代码中进行此操作，但是New-Object System.Collections.ArrayList最终无人居住。例如：
fooChildrenList $fooCollection = [PSCustomObject] @{fooName=""; fooUrl=""; fooChildrenList = New-Object System.Collections.ArrayList}
$fooCollection.fooName = "foo-a-rama"
$fooCollection.fooUrl = "https://1.2.3.4"
$fooChild.childName = "Betsy"
$fooChild.childAge = 6
$fooCollection.fooChildrenList.Add((New-Object PSObject -Property $fooChild))
$fooChild.childName = "Rolf"
$fooChild.childAge = 10
$fooCollection.fooChildrenList.Add((New-Object PSObject -Property $fooChild))

$fooCollection如何将System.Collections.ArrayList添加到PowerShell自定义对象？
