Edit the property of a generated object in powershell

I'm trying to create 8 labels, and edit the .Text property of them.

I've been searching for a while, but have not been able to find anything online. Though, I could be searching this out incorrectly.

Here's an example of what I'm trying to do:

for ($i=1; $i -le 8; $i++)
{
    New-Object -TypeName System.Windows.Forms.Label | New-Variable -name "testing$i"
    $testing$($i).Text = 'text of label'
}

I feel like I'm pretty close, but I've run out of ideas. I wondered if someone may have a resource, or suggestion.

Thanks!

TessellatingHeckler's answer shows you an alternative approach that doesn't require declaring individual variables (one for each label), which is generally preferable.

If you do want label-individual variables, after all:

for ($i=1; $i -le 8; $i++)
{
    New-Object -TypeName System.Windows.Forms.Label | New-Variable -name testing$i
    Set-Variable -Name testing$i  -Value 'text of label'
}

Just like you used the New-Variable cmdlet to create a variable by a dynamically constructed name, you need Set-Variable to set it (assign to it).

As the LHS of an assignment, a $-prefixed token must be followed by a literal variable name, which is why $testing$($i) failed.

Use a collection

$labels = 1..8 | foreach-object { New-Object -TypeName System.Windows.Forms.Label }

$labels | foreach-object { $_.Text = 'text of label' }
