using System.Net.NetworkInformation;

string clientPcName = NetworkInterface.GetAllNetworkInterfaces()
    .Where(ni => ni.OperationalStatus == OperationalStatus.Up && ni.NetworkInterfaceType != NetworkInterfaceType.Loopback)
    .Select(ni => ni.GetPhysicalAddress().ToString())
    .FirstOrDefault();
