wp7 NetworkInterface.GetIsNetworkAvailable（）两个名称空间？

Question

System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();
Microsoft.Phone.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();

Is there a difference between? How to using NetworkInterface.GetIsNetworkAvailable() ?

Answer 1

Microsoft.Phone.Net.NetworkInformation.NetworkInterface inherits from System.Net.NetworkInformation.NetworkInterface and adds the GetNetworkInterface static method and the NetworkInterfaceType static property. Otherwise, the two classes are identical.

You can find a sample using the NetworkInterface.GetIsNetworkAvailable method on MSDN: http://msdn.microsoft.com/fr-fr/library/system.net.networkinformation.networkinterface.getisnetworkavailable(v=vs.95).aspx

 if (NetworkInterface.GetIsNetworkAvailable())
 {
     // Online
 }
 else  
 {
     // Offline
 }
