Powershell foreach executing after pause

Question

I created a script to read a list of names and translate them to IP by using "Resolve-DnsName". I want users to just double click the script and read the output.

cls
Write-Host -ForegroundColor Green -BackgroundColor DarkRed "

|X      | Y     | Z            |

|Capital| 86658 |7417191543242 |
|______________________________|"
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

It happens that the "pause" command at the end is being executed before "foreach".

Press Enter to continue...:

7417191543116  172.18.18.126
7417191543242  172.30.165.50

I can't seem to find a reason for that. Can you guys help out?

It looks similar to the funny things that happen with pipe output and write-host output, where the write-host output will come out first even though it's run after the pipeline. Here's one way to change the order of the output:

$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()

What do you mean with funny things? – markfree Jun 20 '20 at 20:41
You can run write-host after some other pipeline and the output of write-host will come out first. – js2010 Jun 20 '20 at 20:42
