NetworkInterfaceComponent Enumeration
Visual Studio 2010
Specifies the Internet Protocol versions that are supported by a network interface.
Assembly: System (in System.dll)
The values in this enumeration are used by the Supports method to specify the Internet Protocol version supported by a network interface.
The following code example checks whether a network interface supports IPv4.
void DisplayIPv4NetworkInterfaces() { array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces(); IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties(); Console::WriteLine( "IPv4 interface information for {0}.{1}", properties->HostName, properties->DomainName ); System::Collections::IEnumerator^ myEnum23 = nics->GetEnumerator(); while ( myEnum23->MoveNext() ) { NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum23->Current); // Only display informatin for interfaces that support IPv4. if ( adapter->Supports( NetworkInterfaceComponent::IPv4 ) == false ) { continue; } Console::WriteLine(); Console::WriteLine( adapter->Description ); // Underline the description. Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) ); IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties(); // Try to get the IPv4 interface properties. IPv4InterfaceProperties ^ p = adapterProperties->GetIPv4Properties(); if ( !p ) { Console::WriteLine( "No IPv4 information is available for this interface." ); continue; } // Display the IPv4 specific data. Console::WriteLine( " Index ............................. : {0}", p->Index ); Console::WriteLine( " MTU ............................... : {0}", p->Mtu ); Console::WriteLine( " APIPA active....................... : {0}", p->IsAutomaticPrivateAddressingActive ); Console::WriteLine( " APIPA enabled...................... : {0}", p->IsAutomaticPrivateAddressingEnabled ); Console::WriteLine( " Forwarding enabled................. : {0}", p->IsForwardingEnabled ); Console::WriteLine( " Uses WINS ......................... : {0}", p->UsesWins ); } }
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
