PowerShell-将新用户添加到广告组的选择中

我已经创建了一个表单来创建新的广告帐户。脚本的一部分根据新用户的角色（医生、护士、管理员或其他）确定新用户将添加到哪些组，这些角色以下拉选择框的形式在以下代码中捕获：

Write-Host "Based on this information" $FFN "has been added to the following Active Directory Groups:"
Write-Host 

$ADGroup01 = Get-ADGroup "_XA_App_XenApp" |select -expandproperty name -first 1
Write-Host $ADGroup01
$ADGroup02 = Get-ADGroup "Web Proxy Users" |select -expandproperty name -first 1
Write-Host $ADGroup02
if($RadioButton1.Checked -eq $true)
    {
    $ADGroup03 = Get-ADGroup "allrot" |select -expandproperty name -first 1
    Write-Host $ADGroup03
    }
Else
    {
    $ADGroup03 = Get-ADGroup "alltpo" |select -expandproperty name -first 1
    Write-Host $ADGroup03
    }
if ($Role -eq "Doctor" -Or $Role -eq "Nurse")
    {
    $ADGroup04 = Get-ADGroup "PACS Web Access" |select -expandproperty name -first 1
    Write-Host $ADGroup04
    }
if ($Role -eq "Doctor")
    {
    $ADGroup05 = Get-ADGroup "CH-MFD" |select -expandproperty name -first 1
    Write-Host $ADGroup05
    $ADGroup06 = Get-ADGroup "ED-MFP" |select -expandproperty name -first 1
    Write-Host $ADGroup06
    $ADGroup07 = Get-ADGroup "SU-MFD" |select -expandproperty name -first 1
    Write-Host $ADGroup07
    }
Write-Host 

在脚本中，这段代码在实际帐户创建过程中被调用：

Add-ADPrincipalGroupMembership -Identity $UN -memberof $ADGroup01, $ADGroup02, $ADGroup03, $ADGroup04, $ADGroup05, $ADGroup06, $ADGroup07

我面临的问题是，如果用户选择护士、管理员或其他，我会出现以下错误：

添加ADPrincipalGroupMembership:无法验证参数'MemberO'上的参数 参数为null、空或参数集合conta的元素 ins为空值。请提供不包含任何空值的集合，并且 然后重试该命令。“

我知道这是因为在最后一个$ADGroup[x]中没有捕获值，并且没有创建一组if语句来检查每个$ADGroup是否包含数据，我想知道是否有更优雅的解决方案

一如既往，感谢您抽出时间进行回顾，并乐意在需要时提供更多信息

更新-根据@Martin的建议，我在脚本中实现了以下代码

$UN = "zooz"
$Role = "Nurse"
$Department = "Surgical"

If ($Role -eq "Doctor" -and $Department -eq "Surgical")
{
$ADGroups = @(
"PACS Web Access"
"CH-MFD"
"ED-MFP"
"SU-MFD"
)
}

If ($Role -eq "Nurse" -and $Department -eq "Surgical")
{
$ADGroups = @(
"_XA_App_XenApp"
"Web Proxy Users"
"allrot"
)
}

for ($i=0; $i -lt $ADGroups.length; $i++) {
Add-ADPrincipalGroupMembership -Identity $UN -memberof $adgroups[$i] 
}

制作一个对象

$adgroups

，并将所需的组添加到其中

$adgroups = @()

最后使用foreach循环：

$adgroups |添加ADPrincipalGroupMembership-Identity$UN

或（cmdlet是否喜欢流水线输入）

---

谢谢@Martin一个非常干净整洁的解决方案

$adgroups | % { Add-ADPrincipalGroupMembership -Identity $UN -memberof $_ }
