C#.net - Get MAC Address

C#.net - Get MAC Address 

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

view plainprint?

1. public static String GetMACAddress()  
2.        {  
3.            #region Get MAC Address  
4.            try  
5.            {  
6.                ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");  
7.                ManagementObjectCollection moc = mc.GetInstances();  
8.                string MACAddress = String.Empty;  
9.                foreach (ManagementObject mo in moc)  
10.                {  
11.                    if (MACAddress == String.Empty) // only return MAC Address from first card  
12.                    {  
13.                        if ((bool)mo["IPEnabled"] == true) MACAddress = mo["MacAddress"].ToString();  
14.                    }  
15.                    mo.Dispose();  
16.                }  
17.   
18.                MACAddress = MACAddress.Replace(":", "");  
19.                return MACAddress;  
20.            }  
21.            catch (Exception ex)  
22.            {  
23.                throw new Exception(ex.Message);  
24.            }  
25.            #endregion  
26.        }  

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

view plainprint?

1. static void Main(string[] args)  
2.         {  
3.             try  
4.             {  
5.                 System.Console.WriteLine("MAC Address\t:\t" + GetMACAddress());    
6.             }  
7.             catch (Exception ex)  
8.             {  
9.                 System.Console.WriteLine(ex.Message);     
10.             }  
11.         }  

Run the Project.
