How to collect activated checkboxes in powershell

问题

I am using a WPF Application, made in Visual Studio, in Powershell. I am trying to figure out how I can collect activated checkboxes and run a command based on the selection. For now, I am trying to display a message that will show a user their selection to confirm before proceeding to the next step. For some odd reason,

if ($checkbox.checked -eq $true) does not work.

What i am trying to recreate is, if I have a listbox with the following checkboxes (all unchecked when the form starts):

Apples Oranges Bananas

and the user selects Apples & Bananas, I would like a message box to show that the user has selected Apples & Bananas.

[System.Windows.Forms.MessageBox]::Show(" show what the user has selected in this line" , "selection")})

and run commands that would be programmed to those selection.

for a more appropriate context, i am creating a GUI to add users to certain groups (the checkboxes to allow addition to multiple groups at once). I would like to let the user know exactly what user groups they have selected before proceeding to add to those respective groups.

Any help is appreciated, thank you!

The property you want is isChecked, not checked. Simple example:

[xml]$xaml = @"
<Window 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Name="Window" Title="Initial Window" WindowStartupLocation = "CenterScreen"
    SizeToContent = "WidthAndHeight" ShowInTaskbar = "True" Background = "lightgray"> 
    <StackPanel > 
        <CheckBox x:Name="CheckBox1" Content = 'Value for checkbox one'/>
        <TextBox />      
    </StackPanel>
</Window>
"@

$reader=(New-Object System.Xml.XmlNodeReader $xaml)
$Window=[Windows.Markup.XamlReader]::Load( $reader )

$CheckBox1 = $Window.FindName("CheckBox1")

$CheckBox1.Add_Click({
    if($CheckBox1.isChecked) {
        $CheckBox1.Content | Out-Host
    }
})

$Window.Showdialog() | Out-Null

The solution posted by @sodawillow works. If you require to output the user's selection for confirmation purposes, the following bit of code will do just that.

for ($i=#; $i -le #; $i++){ if ($listbox.items.item($i).isChecked -eq $true)

{$string = $listbox.items.item($i).content $collectionstring = @("$collectionstring" + "$string")}} [System.Windows.Forms.MessageBox]::Show("$collectionstring" , "Status")
