event handler to detect changes in netstat data

Question

I know .net allows a method to detect if your network IP has changed via System.Net.NetworkInformation. I would like to be able to detect changes to the number of TCP or UDP connections to a computer.

So instead of scraping the IP end points every x seconds I want the system to notify me of new connections or dropped connections.

Are there any event handlers for this?

I use c#.
