如何在 powershell 数组中写入托管元素的单个属性？

Question

我查询 Office365 以获取与Chris的 displayName 匹配的所有用户的列表。

我想提示用户他们想要选择哪个克里斯。这样做时，我有以下 for..each 代码

$tmpUserOffice = Get-MsolUser -SearchString "*Chris*"
if ($tmpUserOffice -is [array])
{
    if ($tmpUserOffice.Count -lt 50) {
        Write-Host "Many matching users in MSOL. Choose which one you want to save"    
        for ($i = 0; $i -lt $tmpUserOffice.Count; $i++) {
            Write-Host $i " "  $($tmpUserOffice[$i].DisplayName) 
        }   
        Write-Host $tmpUserOffice.Count " None of the above" 
        $chosen = Read-Host

        if ($chosen -eq $tmpUserOffice.Count) {
            Write-Warning "Nothing found. Try searching with different criteria or use wildcards"
            Write-Output $null
        }

        Write-Host $tmpUserOffice[$chosen] " selected" 
        $tmpUserOffice = $tmpUserOffice[$chosen]
        exit
    }
    else {
        Write-Warning "More than 50 matches found. Try searching for more specific criteria"
    }
}

我的问题之一是如何让以下行的内容完成

Write-Host $i " "  $($tmpUserOffice[$i].DisplayName) 

目前的输出是

Many matching users in MSOL. Choose which one you want to save 
0
1
2  None of the above

我需要进行哪些更改才能确保该值实际写入一个值？

^{编者注：该问题与此处发布的代码无关，原则上确实有效。}

我认为你只需要把它用双引号引起来：

Write-Host "$i  $($tmpUserOffice[$i].DisplayName)"

双引号允许您嵌入变量$i，并且$(...)允许在显示之前对值进行评估。
