Hi, everyone

i'm a confused where to use the following code because i'm new to C#, i have created a console application and paste the code but it didn't work:

C#

string mac = "";
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
            {
 
                if (nic.OperationalStatus == OperationalStatus.Up && (!nic.Description.Contains("Virtual") && !nic.Description.Contains("Pseudo")))
                {
                    if (nic.GetPhysicalAddress().ToString() != "")
                    {
                        mac = nic.GetPhysicalAddress().ToString();
                    }
                }
            }
MessageBox.Show(mac);

You said that you have created a Console application, but there is MessageBox.Show in the code. This method is used in Windows Forms and WPF applications to show a message box, not in Console applications. Instead, use Console.WriteLine:

C#

Console.WriteLine(mac);

There is some misunderstanding of Console applications; and your answer may support this misunderstanding.
Console and Windows applications are not mutually exclusive. It's just Visual Studio properties windows creates this confusion. In reality, "Console application" options means "create a console", and "Windows application" does not really mean "create windows application", it means "create some application not showing a console".

That means, that you create windows application which also has console. If you don't use "Console application" option, the console won't show, but you still can use console functions which output... nowhere.
