create an object from returned variables of a foreach powershell

Question

I am trying to create a script that receives a list of computers and for-each computer I need to create a process, after running the process, I have many variables that y need to append to a an object

How can I append to the object, the returned info of the pcs?

#input variable that the foreach need to process
$Machines = "pc1,pc2,pc3,pc4,pc5,pc6,pc7,pc8,pc9,pc0"


#create empty object
$pcNull
$MachineNull
$usersNull    
$object= New-Object Object
$object | Add-Member NoteProperty propiedad $MachineNull
$object | Add-Member NoteProperty users $usersNull
$object | Add-Member NoteProperty computer $pcNull
$object | Add-Member NoteProperty error $false


foreach ($Machine in $Machines  )
{
 #where i make a process foreach computer and there are variables that are returned 
 {
 }
 ###############################
 #where i am trying to append to the created object the returned variables

 #append to propiedad property
 $object.propiedad = $object.propiedad = $MachineNull 
 $object
 #append to users property
 $object.users = $object.users = $false
 $object
 #append to computers property
 $object.computer = $object.computer = $Machine
 $object
}


$object

Solution

You're probably better off creating multiple objects, one per computer, inside the foreach loop.

# Loop through machines, assign all output to $Objects variable
$Objects = foreach ($Machine in $Machines)
{
    #where i make a process foreach computer and there are variables that are returned 
    {
    }
    ###############################
    #where i am trying to append to the created object the returned variables

    # Define the properties that the object should have in a hashtable
    $ObjectProperties = @{
        # Assuming you've assigned something to $Propriedad, $Users and $ErrorState above
        Propiedad = $Propriedad
        Users     = $Users
        Computer  = $Machine
        Error     = $ErrorState
    }

    # Now create an object. 
    # When we just drop it in the pipeline like this, it gets assigned to $Objects
    New-Object psobject -Property $ObjectProperties
}

Now you can create HTML from your objects with ConvertTo-Html:

$Objects | ConvertTo-Html -As Table -Head "<title>Kimo's report</title>"

If you want to test it, you'll need to change $Machines to:

"pc1","pc2","pc3","pc4","pc5","pc6","pc7","pc8","pc9","pc0"

If you want to save this as a .ps1 script file and be able to pass the computer names as arguments, add a param() block at the top:

param([string[]]$Machines)

Now, if you save the script as "KimosReporter.ps1", you can run it against any computer like this:

PS C:\>.\KimosReporter.ps1 -Machines "pc1","pc6","pc9"
