PowerShell Objects

PowerShell Objects can be a great help when handling data. I usually use these to store information and save it to an array for later use of export to a CSV file for reporting. Below is a older version of creating a PowerShell object and assigning values, this works on PowerShell 2.0 and above.

Good Article on Object and the Differences

This is an older school style of a PowerShell Object:

$Obj=New-Object PSObject
$Obj |Add-Member NoteProperty MyName ("Scott Head")
$Obj |Add-Member NoteProperty MyHome ("Redondo")
$Obj |Add-Member NoteProperty MyCar ("Mustang")
$Obj |Add-Member NoteProperty MyJob ("Chevron Oil")

Return $Obj

A Newer format for PowerShell objects shown as below:

#Declare Array For Storing Multiple Object Data
$MyObjectArray=@()

#Create and Populate Object Data and Assign Value to Variable
$MyObjectVariable=[PSCustomObject]@{
FirstName = "SCOTT"
LastName = "HEAD"
Location="Redondo"
Job="Sr. Systems Admin"
SomeNUmber=455
}

#Create and Populate Object Data and Assign Value to Variable
$MyObjectVariable2=[PSCustomObject]@{
FirstName = "Joseph"
LastName = "Smith"
Location="Venice Beach"
Job="Teacher"
SomeNUmber=5
}

#Populate Array With Object Data
$MyObjectArray+=$MyObjectVariable2
$MyObjectArray+=$MyObjectVariable

#Access A Property of the Object
Write-Output $MyObjectArray.SomeNumber

PowerShell Inline Object Access

PowerShell Objects are usually the results of a query like the example below that pulls the information on Windows Services on a computer. All the data is in an object oriented format where it can by refernece using $_.Property.

Get-service | Where{$_.Status -eq "Running"}
