Dear Friends,

I want to get client side MACID. But i got server side MACID when had using the below code.

protected void Page_Load(object sender, EventArgs e)
   {
       ManagementObjectSearcher objQuery = null;
       ManagementObjectCollection queryCollection = null;

       try
       {
           objQuery = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");

           queryCollection = objQuery.Get();

           foreach (ManagementObject mgmtObject in queryCollection)
           {
               if (mgmtObject["MacAddress"] != null)
               {
                   Response.Write(mgmtObject["MacAddress"].ToString());
               }
           }
       }
       catch (Exception ex)
       {
           Response.Write(ex.Source);
           Response.Write(ex.Message);
       }
   }

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();
                Response.Write(sMacAddress);
            }
        }

Please give me the sample coding.
