Powershell Get-ADUser 已计算属性 Select-对象：无法转换 System.String[]？

Question

下面这个工作正常，没有问题：

$properties = 'Name,msExchRemoteRecipientType,msExchRecipientDisplayType,msExchRecipientTypeDetails,proxyAddresses' -split ','
Get-ADUser -identity 'Lee.Xia' -Properties $properties |
Select-Object $properties

但是下面这个格式的电子邮件地址只用 SMTP 不起作用？添加此行：@{Label = 'Email Address'; Expression = {($_.proxyAddresses | Where-Object {($_ -like 'SMTP*') -and ($_ -notlike '*onmicrosoft.com') } | Sort-Object -CaseSensitive -Descending | ForEach-Object {$_.Split(':')[1]}) -join ', ' }}

所以它会像：

$properties = 'Name,msExchRemoteRecipientType,msExchRecipientDisplayType,msExchRecipientTypeDetails,proxyAddresses' -split ','
Get-ADUser -identity 'Lee.Xia' -Properties $properties |
Select-Object $properties, @{Label = 'Email Address'; Expression = {($_.proxyAddresses | Where-Object {($_ -like 'SMTP*') -and ($_ -notlike '*onmicrosoft.com') } | Sort-Object -CaseSensitive -Descending | ForEach-Object {$_.Split(':')[1]}) -join ', ' }}

这是错误代码：

Select-Object : Cannot convert System.String[] to one of the following types {System.String, System.Management.Automation.ScriptBlock}.

Answer 1

Select-Object 的 -Property 参数需要单个属性或属性数组。由于 $properties 已经是一个数组，您需要使用 + 而不是 ,.

将计算出的属性添加到其中

$properties = 'Name,msExchRemoteRecipientType,msExchRecipientDisplayType,msExchRecipientTypeDetails,proxyAddresses' -split ','
Get-ADUser -identity 'Lee.Xia' -Properties $properties |
Select-Object ($properties + @{Label = 'Email Address'; Expression = {($_.proxyAddresses | Where-Object {($_ -like 'SMTP*') -and ($_ -notlike '*onmicrosoft.com') } | Sort-Object -CaseSensitive -Descending | ForEach-Object {$_.Split(':')[1]}) -join ', ' }})

使用 , 而不是 + 创建一个包含两个元素的数组。第一个元素是 $properties 的数组。第二个元素是计算出来的属性。 Select-Object 不会将其展开为单个数组。
