Remarks

The NetworkChange class raises NetworkAvailabilityChanged events when the availability of the network changes. The network is available when at least one network interface is marked "up" and is not a tunnel or loopback interface.

To have a NetworkChange object call an event-handling method when a NetworkAvailabilityChanged event occurs, you must associate the method with a NetworkAvailabilityChangedEventHandler delegate, and add this delegate to this event.
