Store output of ForEach into array in powershell

Question

$data = @("server1","server2","server3")

foreach ($server in $data) {
    $results = (Test-Connection $server -count 1 | Measure-Object -Property ResponseTime -Average).Average
}

I'm trying to figure out how to take the output of a ForEach and store the results into an array so I may then compare them later. I could not come up with a way to do this yet.

Solution 1

    $FinalResult = @()
    $data = @("server1","server2","server3")
    foreach ($server in $data) {
        $results = (Test-Connection $server -count 1 | Measure-Object -Property ResponseTime -Average).Average

        $FinalResult += New-Object psobject -Property @{
                        ServerName = $server
                        Result = $result
                        }  
    }
   $FinalResult | Select ServerName, Result | Export-Csv ".\FinalResult.csv" -NoTypeInformation

Please let me know if this snippet doesn't work, i will do the needful.

By doing the ForEach, you're just measuring the value of the property of a scalar (single) object. The average will always be just the value of that property.

Test-Connection will accept an array of names as the -ComputerName parameter, so the ForEach isn't really necessary at all.

 $data = @("server1","server2","server3")

 $results = Test-Connection $data -count 1 | select -ExpandProperty ResponseTime
