Create multiple instances of custom Powershell object

instance, object, powershell

Solution

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.

Problem

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 ```
