Gracefully stopping in Powershell

Question

How do I catch and handle Ctrl+C in a PowerShell script? I understand that I can do this from a cmdlet in v2 by including an override for the Powershell.Stop() method, but I can't find an analog for use in scripts.

I'm currently performing cleanup via an end block, but I need to perform additional work when the script is canceled (as opposed to run to completion).

The documentation for try-catch-finally says:

A Finally block runs even if you use CTRL+C to stop the script. A Finally block also runs if an Exit keyword stops the script from within a Catch block.

See the following example. Run it and cancel it by pressing ctrl-c.

try {     while($true)     {         "Working.."         Start-Sleep -Seconds 1     } } finally {     write-host "Ended work." }
