Question

im writing a script to get services from local and remote machines. I’ve had to split the wmi call for local and remote machines (remote machines require different credentials). I want to output them as System.Object. How do i create a function for the output of system.object?

heres the code i have so far:

$objServicecol = @()

    # how do i get AddService object back 
    Function AddServiceObjects
    {
            ForEach ($Service in $Services)
            {
                $objService = New-Object System.Object
                $objService | Add-Member -MemberType NoteProperty -Name SystemName -Value $Services.SystemName 
                $objService | Add-Member -MemberType NoteProperty -Name Name -Value $Services.Name 
                $objService | Add-Member -MemberType NoteProperty -Name StartMode -Value $Services.StartMode
                $objService | Add-Member -MemberType NoteProperty -Name StartName -Value $Services.StartName
                $objService | Add-Member -MemberType NoteProperty -Name Status -Value $Services.Status
                #$objServiceCol += $objService
                AddServiceObjects += $objService
            }
        }

    # Executes local WMI 
    If ($Servers -contains "localhost") 
    {
        $Services = Get-WMIObject Win32_Service -ComputerName "localhost" | Select-Object SystemName, Name, StartMode, StartName, Status
        AddServiceObjects $Services
    }
...#execute remote wmi...

In .NET, System.Object is the root of the inheritance hierarchy so any type you output can be treated as a System.Object. You might want to consider creating a psobject instead of a System.Object in your loop (and simplify it):

Function AddServiceObjects($Services)
{
    ForEach ($service in $Services)
    {
        New-Object psobject -Property @{
            SystemName = $service.SystemName
            Name       = $service.Name 
            StartMode  = $service.StartMode
            StartName  = $service.StartName
            Status     = $service.Status }
     }
}

Note that by virtue of not assigning the New-Object output to a variable it will get output from the function – one object for every iteration through the loop. Also note that your foreach iteration variable was $service but your were referencing the global $Services in your New-Object command.
