NetworkChange.NetworkAvailabilityChanged Event

 

Occurs when the availability of the network changes.

Namespace:   System.Net.NetworkInformation
Assembly:  System (in System.dll)

static member NetworkAvailabilityChanged : IEvent<NetworkAvailabilityChangedEventHandler,
    NetworkAvailabilityEventArgs>

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.

The NetworkAvailabilityChanged event is supported on Windows 2000 and later.
