Powershell - Find dublicate values in custom object arraylist-CodePudding

I've got an Arraylist with custom objects and want to find all objects where "Jobname" is identical. Group-Object does not work the way I wanted it because it just counts all properties (10). I'm even starting to think that I'm using the Arraylist wrong. The creation of the objects in the code is just for testing, in reality I'm using a loop to fill my Array.

$global:BackupJobObjectArray = New-Object System.Collections.ArrayList

function AddBackupJobFoldertoArray ($jobservername, $backupjobfolder, $backupjobname, $jobmandant, $size, $sizeGB, $sizeTB, $BackupServer, $vbkcount, $lastmodifiedfile)
{
    $BackupJobObject = New-Object System.Object
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "Jobname" -Value $backupjobname
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "Mandant" -Value $jobmandant
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "Servername" -Value $jobservername
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "Filepath" -Value $backupjobfolder
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "Size" -Value $size
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "SizeGB" -Value $sizeGB

    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "VBKCount" -Value $vbkcount
    $BackupJobObject | Add-Member -MemberType NoteProperty -Name "LastModified" -Value $lastmodifiedfile
    $global:BackupJobObjectArray.Add($BackupJobObject) | Out-Null
}

$global:BackupJobObjectArray | ForEach-Object {$_.psobject.Properties | Group-Object { $_.Jobname } | Format-Table}

CodePudding user response：

Use Script-scoping instead of Global as that should be more than enough.
Then use $script:BackupJobObjectArray only inside the fuction, because outside the list is known anyway.

Instead of all those Add-Member lines, you can simply use [PsCustomObject] and add that straight away to the list.

Then finally, if I understand your question correctly, you woud like to get a table formatted list of the duplicate objects based on the JobName, and this you can do like below

$BackupJobObjectArray = [System.Collections.Generic.List[object]]::new()

function AddBackupJobFoldertoArray {
    param(
        [string]$jobservername, 
        [string]$backupjobfolder, 
        [string]$backupjobname,
        [string]$jobmandant, 
        [int64]$size, 
        [int64]$sizeGB, 
        [int64]$sizeTB, 
        [string]$BackupServer, 
        [int]$vbkcount, 
        [string]$lastmodifiedfile
    )
    $script:BackupJobObjectArray.Add([PsCustomObject]@{
        Jobname      = $backupjobname
        Mandant      = $jobmandant
        Servername   = $jobservername
        Filepath     = $backupjobfolder
        Size         = $size
        SizeGB       = $sizeGB
        SizeTB       = $sizeTB
        Backupserver = $BackupServer
        VBKCount     = $vbkcount
        LastModified = $lastmodifiedfile
    })
}

Personally I would go for a List object, but an ArrayList would also do.
