How to get MAC ID of a system using C#

Question

I am building a C# application and I want to fetch the MAC ID of the system. I have found many code snippets, but they either give wrong answers or throw exceptions. I am not sure which code snippet is giving the right answer. Can someone provide me the exact code snippet that fetches the MAC ID?

This will help you.

public string FetchMacId()
{
    string macAddresses = "";

    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (nic.OperationalStatus == OperationalStatus.Up)
        {
            macAddresses += nic.GetPhysicalAddress().ToString();
            break;
        }
    }
    return macAddresses;
}
