Powershell: Event in Foreach loop

Question

I'm having problems with a foreach loop and setting a Add_MouseClick event.

Each loop the function generates a new clickable label. While the .Text variable setting works as intended, when setting the event listener, it will write out the last generated $labelName, regardless of which is clicked.

foreach($account in $resUserNameSearchArray){
    #Set form object variables
    $script:labelName = "res" + $i 

    #Form Variable
    Set-Variable -Name $labelName -Value (New-Object System.Windows.Forms.Label)
    (Get-Variable $labelName -ValueOnly).Text = "$account"
    (Get-Variable $labelName -ValueOnly).Add_MouseClick{  
        Write-Host "$labelName"
    }...

There's a few non-relevant lines removed (location, font,etc)

Here is the rest of the function's code pastebin.com/Bx4g2nx7 — Joshua Williams

Yes, I've been working through it piece by piece. Calling Write-Host $labelName outside of the Add_MouseClick event works as intended, it appears to only occur when it's wrapped in that event. — Joshua Williams

Your click action is going to be evaluated at when you click it. So $labelname will be what it is at that moment (the last created), not what it was when the click action was made. So you need to get what label was clicked from inside the mouse click, which I can't think of how to do off the top of my head. — BenH

That got me where I needed! Write-Host $this.text did it! Thank you. — Joshua Williams

I needed to use Write-Host $this.text within the Add_Click event to pull in the .text of the foreach variable.
