Hello,

Why we need LAN network connectivity for Get MAC Address using c# .net?

When i disabled LAN network so, did not get MAC Address, Why?

I want to Get MAC Address without LAN Network, is it Possible?

I have used both code also:-
First:-
public static String GetMACAddress()
{
#region Get MAC Address
try
{
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
string MACAddress = String.Empty;
foreach (ManagementObject mo in moc)
{
if (MACAddress == String.Empty) // only return MAC Address from first card
{
if ((bool)mo["IPEnabled"] == true) MACAddress = mo["MacAddress"].ToString();
}
mo.Dispose();
}

MACAddress = MACAddress.Replace(":", "");
return MACAddress;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
#endregion
}

Second:-

public string GetMACAddress()
        {
            NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
            String sMacAddress = string.Empty;
            foreach (NetworkInterface adapter in nics)
            {
                if (sMacAddress == String.Empty)// only return MAC Address from first card
                {
                    IPInterfaceProperties properties = adapter.GetIPProperties();
                    sMacAddress = adapter.GetPhysicalAddress().ToString();
                }
            } return sMacAddress;
        }

But my purpose is not solving.

Please help me.

Thanks in Advance.
