C#.net - Get MAC Address through C#.net

Sometime in our application we need to fetch MAC Address of network adapter card.In this article i will show you how to get a MAC Address.


Step 1
Create a Console Application and give the solution name as  ConMACAddress.


Step 2
Add System.Management assembly reference to the project from solution explorer,it is look like this

Step 3
Write a static method for get MAC Address,it is look like this

 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
        }

Step 4
Call above function in main method,it is look like this

static void Main(string[] args)
        {
            try
            {
                System.Console.WriteLine("MAC Address\t:\t" + GetMACAddress());  
            }
            catch (Exception ex)
            {
                System.Console.WriteLine(ex.Message);   
            }
        }

Run the Project.
