如何阻止 Powershell WPF 表单关闭

Question

I have been trying to implement a way to stop the user from manually clicking the red 'x' on my WPF form in Powershell. Research online indicates that the best way to do is to use a the form closing event, stop the event and hide the form instead. It seems there are many methods of doing so in C# but i cant seem to find any for Powershell. For example, something like this can be used in C#.

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        e.Cancel = true;
        this.Visibility = Visibility.Hidden;
    } 

is there anything equivalent I could use in Powershell?

The event for form closing in Powershell is add_Closing , but I cant figure out how to stop the closing of the form.

Answer 1

For anyone interested, this is how simple it was:

 $form.add_closing
    ({
        $_.cancel = $true 
    })

Just a quick note, this will work if you are using a WPF form. If you are using a WinForm, you will have to use the [System.Windows.Forms.FormClosingEventHandler] to make it work.
