    For example:
    When I use System.Windows.Forms.Form, there is the event "OnClosing". So, when I close a form, some code can be executed.

    Can I do something like this, when I stop my powershell script when it is running?

    Seems like a syntax error, try below it will work:

    function Test-Block {
    [cmdletbinding()]
    param (
        # Parameter help description
        [Parameter(Mandatory=$false)]
        [System.String]
        $Str
    )
    try {
        $q = read-Host -Prompt "oo:"
    }
    catch {

    }
    finally {
        Write-Host "`nTerminated" -ForegroundColor Red
    }
}

Test-Block

    You can try using the Finally block.

    function Test-Block {
    [cmdletbinding()]
    param (
        # Parameter help description
        [Parameter(Mandatory=$false)]
        [System.String]
        $Str
    )
    try {
        $q = read-Host -Prompt "oo:"
    }
    catch {

    }
    finnaly {
        Write-Host "terminated"
    }
}

    When I start this script, I need to type something. 
    I want to press Ctrl+C or stop button in ISE or VS Code and execute code 

    Write-Host "terminated"

    I tried using finally, but it didn`t help

    It doen`t work in VS code but it works in ISE. 

    Please, explain how does Ctrl+C work... 
    Does it raise an exception?

    CTRL+C generally works as a terminate action for the powershell ISE. You could think of it as an interrupt signal that would terminate the running process (script). You could refer below for detailed explanation:

    https://blogs.technet.microsoft.com/dsheehan/2018/10/27/powershell-taking-control-over-ctrl-c/

    I guess that the windows processes could have been able to customize the behavior of such key presses, what is a terminating signal for powershell might not be the same for VSCode. That might be the reason why it would not be working on the VS Code. It's just a blind guess.

    Please let me know if you find the exact cause of such behavior, it would be helpful.
