Question

我创建了一个脚本来读取名称列表，并使用“ Resolve-DnsName”将其转换为IP。我希望用户只需双击脚本并阅读输出即可。

cls
Write-Host -ForegroundColor Green -BackgroundColor DarkRed "

Write-Host "`n`n"


$estacoes = @(
    'esbsa9908ee43',
    'esbsa009908jc1',
    '7417191543366',
    'esbsa9908ee18',
    '7417191543116',
    '7417191543242'
)

ForEach ($estacao in $estacoes){
    Resolve-DnsName -ErrorAction Continue -Type A -QuickTimeout -Name $estacao | Select-Object Name,IpAddress
    }

Pause

碰巧最后一个“暂停”命令在“ foreach”之前执行。

Press Enter to continue...:

7417191543116  172.18.18.126
7417191543242  172.30.165.50

我似乎找不到原因。你们可以帮忙吗？

它看起来与管道输出和写主机输出中发生的有趣事情相似，在写输出主机中，即使它在管道之后运行，也将首先输出。这是更改输出顺序的一种方法：

$estacoes = echo microsoft.com yahoo.com
$result = ForEach ($estacao in $estacoes){
    Resolve-DnsName -ErrorAction Continue -Type A -QuickTimeout -Name $estacao | 
      Select-Object Name,IpAddress 
    }

$result | format-table

pause

# didn't work
# 'Press Enter to continue...:'
# [void][console]::readkey()

暂停后执行Powershell foreach
