-PipelineVariable isnt working correctly

PowerShell Help
21

Pipeline variable keeps the reference, The newly added member is also present in the pipeline variable which is represented in New column

[PSCustomObject]@{Column1=1;Column2=2} | Select-Object -Property * -PipelineVariable rr | Foreach-Object -Process {$_.Column1=5;$_|Add-Member -MemberType NoteProperty -Name Column3 -Value 6;$_} | Select-Object -Property *,@{E={$rr};L='New'}

Column1 Column2 Column3 New
------- ------- ------- ---
      5       2       6 @{Column1=5; Column2=2; Column3=6}

Hmm, I guess that’s true of all properties.

$a = [pscustomobject]@{message='hi'}
$b = $a
$a.message = 'there'
$b.message

there

Update from my last post back using your approach a bit differently. “correction pasted the wrong one”

[/quote] Not sure if it's a response to JS, but if for me, the results are wrong here, unless the system was already the same states as in the csv file.

A way to copy the values of an object (clone) (Powershell: Everything you wanted to know about PSCustomObject). Why does psobject have to be hidden?

$a = [pscustomobject]@{message='hi'}
$a.message
hi

$b = $a.psobject.copy()
$b.message
hi

$a.message = 'there'
$a.message
there

$b.message
hi
