How do I check for a network connection?

Question

What is the best way to determine if there is a network connection available?

Accepted Answer

You can check for a network connection in .NET 2.0 using `GetIsNetworkAvailable()`:

```
System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()
```

To monitor changes in IP address or changes in network availability use the events from the NetworkChange class:

```
System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged
System.Net.NetworkInformation.NetworkChange.NetworkAddressChanged
```
