Powershell custom objects

Question

Hi Folks
I was wondering why a PS custom object will not be displayed according to sequence? It will be displayed last no matter what.

`$table= @()
$table += New-Object psobject -Property @{SID ="ola";MG="$MG"}

$table

write-host "lol"`

Output:
Notice that the string "lol" displayed first regardeless

lol
SID MG

Answer 1

It has nothing to do with PSCustomObject. The statement "$table" is sent to stream 1 (the "Success" stream). Write-Host is sending the output directly to the host. If you want them written in the order you expect, use Write-Output instead of Write-Host.

Hi,

The object $table is sent to the pipeline that the script is runing and will be piped to Out-Default by default

Answer 3

It's hard to understand your code. But usually objects are implicitly sent through format-table, which has a slight delay so it can see how to align columns.

Answer 4

This is likely an implementation detail (there's a difference between standard output and host-only output).
