How do I remove Error. My logic for notcontains is flawed

March 29, 2022

I build an array of objects and I am interested in recording if there is an error.
Array of objects starts out like this

[array]$UsersResults = $GSuspend | ForEach-Object {
    gam update user $_.primaryEmail archived on | Out-Null
    [PSCustomObject]@{
        Email = $_.primaryEmail
        Error = $LASTEXITCODE
    }
}

I simply want to know if any error is not 0.

If every error is 0. Later down my script I remove the error column from the array but I am pretty sure the following logic below is flawed.

If (-not ($UsersResults.error -notcontains 0)) {

Is there a simple way for me to find a error number above 0 or only add error to the array in the top part of the script if an error is found?

>Solution :

Use Where-Object to filter the array based on the value of the Error column:

$failedResults = $UsersResults |Where-Object Error -ne 0

if($failedResults.Count -gt 0){
    Write-Warning "'$($failedResults.Count)' errors occurred!"
}
else {
    Write-Host "No errors occurred!"
}

If you want the result to just be a flat array of Email adresses, use $UsersResults.Email or $UsersResults |ForEach-Object Name. If you want a new array of objects with the Email property preserved, but no Error property, use $UsersResults |Select-Object Email
