获取DNS服务器列表

public static void DisplayDnsAddresses()
        {
            NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface adapter in adapters)
            {

                IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
                IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
                if (dnsServers.Count > 0)
                {
                    Console.WriteLine(adapter.Description); //网卡的信息
                    foreach (IPAddress dns in dnsServers)
                    {
                        Console.WriteLine("  DNS Servers ............................. : {0} )",dns); //所配置的DNS
                    }
                }
            }
        } 

 

上面这些类在2.0中可以直接使用
