c#, NETWORKLIST.NetworkListManager 예

Vista 이후에, 네트워크 연결 관리자에서 현재 연결된 활성 네트워크 조회 코드 예제.
서버 모니터링에 필요해서... 어렵지 않아요~~^^

NETWORKLIST.NetworkListManager _nlManager = new NETWORKLIST.NetworkListManager();

foreach(NETWORKLIST.INetwork _network 

  in _nlManager.GetNetworks(NETWORKLIST.NLM_ENUM_NETWORK.NLM_ENUM_NETWORK_CONNECTED)) {
    Console.WriteLine(_network.GetName());
    Console.WriteLine(_network.GetCategory());

    foreach(NETWORKLIST.INetworkConnection c in _network.GetNetworkConnections()) {
        var k = from _nis in NetworkInterface.GetAllNetworkInterfaces() 

              where _nis.Id == c.GetAdapterId().ToString("B").ToUpper() select _nis;

        if (k != null & k.Count() > 0) {
            NetworkInterface _ni = k.FirstOrDefault();
            Console.WriteLine(_ni.Id);
            Console.WriteLine(_ni.Name);
        }
    }
}
