Create multiple instances of custom Powershell object - powershell

Question

I am creating a new object in a Powershell script, or actually an object type. I want to create multiple instances of this object. How do I do this?
The code below is what I am working on, it appears that all instances in the array reference the same object, containing the same values.
# Define output object
$projectType = new-object System.Object
$projectType | add-member -membertype noteproperty -value "" -name Project
$projectType | add-member -membertype noteproperty -value "" -name Category
$projectType | add-member -membertype noteproperty -value "" -name Description
# Import data
$data = import-csv $input -erroraction stop
# Create a generic collection object
$projects = #()
# Parse data
foreach ($line in $data) {
$project = $projectType
$project.Project = $line.Id
$project.Category = $line.Naam
$project.Description = $line.Omschrijving
$projects += $project
}
$projects | Export-Csv output.csv -NoTypeInformation -Force

You have to use New-Object for any, well, new object, otherwise being a reference type $projectType in your code refers to the same object. Here is the changed code:
# Define output object
function New-Project {
New-Object PSObject -Property #{
Project = ''
Category = ''
Description = ''
}
}
# Parse data
$projects = #()
foreach ($line in 1..9) {
$project = New-Project
$project.Project = $line
$project.Category = $line
$project.Description = $line
$projects += $project
}
# Continue
$projects
In this particular case instead of using the function New-Project you can just move its body into the loop, e.g. $project = New-Object PSObject …. But if you create your “projects” elsewhere then having this function will be useful there as well.
