回答1:

Check NetworkInterfaceType. If Internet is available then It should be other than None

 return (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType != 
 Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None);

回答2:

In the Windows Phone Emulator it's correct that NetworkInterface.GetIsNetworkAvailable() will always return true. Even if your PC has no internet connection, the emulator counts the local/internal connection to your PC.

The return value will be false if you test your application on a real device and switch it e.g. in flight-mode.

Yes NetworkInterface.GetIsNetworkAvailable() will always return true on windows phone emulator you can try below code to detect network availability.

using Microsoft.Phone.Net.NetworkInformation;    
    if (DeviceNetworkInformation.IsNetworkAvailable)
    {
    MessageBox.Show("network available") ;              
    }
    else
    {
    MessageBox.Show("No network.") ;   
    }
