how to fire an event within the object

Question

Hi, Im developping my filesyncer project and I got stuck.

There is a ServiceBased DB which holds this FolderPair object:

 

https://pastebin.com/Wfpbndw1

 

When the application start, there is a Static Class that holds these folder pairs in a List.

 

I'd these FolderPairs fire an event, when a file arriver into the Source, and Immadiately move that File to Destination.

 

I dont know how to achieve this. How could an object be the Issuer and the Subscriber in itself?

Or should I intruduce a new static class , lets say "Worker" who subscribe to all FolderPairs's watchdog's Created Event and do the file copy?

 

How shoudl this be done?

Thanks,
