不耻求教MSND的怎么查询

最近学习ASP.NET,想读取网卡信息，于是上网查了下要用ManagementClass ManagementObjectCollection 这些类。
方式如下
C# code

            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            int i = 0;
            foreach (ManagementObject mo in moc)
            {
                if ((bool)mo["IPEnabled"] == true)
                {
                    NetInfo[i].MacAddress = mo["MacAddress"].ToString();
                    NetInfo[i].IPAddress = (mo["IPAddress"] as String[])[0];
                    NetInfo[i].IPSubnet = (mo["IPSubnet"] as String[])[0];
                    NetInfo[i].DefaultIPGateway = (mo["DefaultIPGateway"] as String[])[0];
                    i++;
                }
            }

我在MSDN上找到了这些类。但是想MacAddress ，IPAddress 这些属性就没找到，我想请教下给位大大是怎么找到这些东西的

百度、google都可以查查，咳咳，能上网一切都好办

第一次SF，小小的开心下
