本地IP地址
using System.Net;

IPHostEntry ipHost = Dns.Resolve(Dns.GetHostName()); ;
IPAddress ipaddress = ipHost.AddressList[0];
string ips = ipaddress.ToString();

MAC地址
 string strMac = "";
 NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface ni in interfaces)
            {
                if (ni.OperationalStatus == OperationalStatus.Up)
                {
                    strMac += ni.GetPhysicalAddress().ToString() + "|";//MAC地址
                }
            }
ni.OperationalStatus.ToString();//网络连接状态

C# code

ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration  where IPEnabled='True' and MACAddress = '" + MACAddress + "'");
                  ManagementObjectCollection queryCollection = query.Get();
                  foreach (ManagementObject mo in queryCollection)
                  {
                      if ((bool)mo["IPEnabled"] == true)
                      {
                          if (mo["IPAddress"] != null)
                              strIP = ((string[])mo["IPAddress"])[0];
                      }
                      else
                      {
                          strIP = "0.0.0.0";
                      }
                  }
