To fetch or get the MAC Address in C# application we have to use “Win32_NetworkAdapterConfiguration” WMI class. This class represent the attributes and behavior of the network adapter card. This class includes extra properties and methods that support the management of the TCP/IP and Internetwork Packet Exchange (IPX) protocols that are independent from the network adapter. These are the list of the Properties of the “Win32_NetworkAdapterConfiguration” class.

Note:- The “Win32_NetworkAdapterConfiguration” class is present under the System.Management Namespace. So before using the “Win32_NetworkAdapterConfiguration” class you must add the refrence of System.Management namespace in your project.
Here is the a function written in c#, that return the MAC address of the system
private string GetMacAddress()
{
string macid = string.Empty;
ManagementClass mac = new ManagementClass(“Win32_NetworkAdapterConfiguration”);
ManagementObjectCollection macObjCol = mac.GetInstances();
foreach (ManagementObject mo in macObjCol)
{
if (macid.Equals(string.Empty))
{
if ((bool)mo["IPEnabled"] == true)
{
macid = mo["MacAddress"].ToString();
mo.Dispose();
}
}
}
return macid;
}
Used Namespace
System.Management;
