handle powershell event in custom cmdlet code

Question

I'm trying to stop remote powershell job gracefully by using event. There are some good examples to do this with powershell cmdlets (e.g. this one).

But I don't know how to do the same thing from my custom cmdlet in C# code.

My solution is like following:

1. Invoke CustomCmdlet as job in remote machine:

   Invoke-Command -Session $sess -AsJob -ScriptBlock { CustomCmdlet }

2. Inside my CustomCmdlet C# code

    protected override void ProcessRecord()
    {
        // Question: How to write the C# code for following cmdlet? How to set my CancelJob function in the Action parameter?
        // Register-EngineEvent -SourceIdentifier MyEventSource -Action { CancelJob() }
   
        // Start a new task thread to run the real task
    }
   
    private void CancelJob()
    {
       // Get the event to cancel the job. 
       // Notify the task thread to clean up server resource and exit
    }
   

3. When need to cancel the job, send an event to remote machine:

Invoke-Command -Session $sess -AsJob -ScriptBlock {New-Event -SourceIdentifier MyEventSource -MessageData "CancelTheJob" }

Thanks a lot!
