Question

What is the C# equivalent of this code ? [URL]https://support.microsoft.com/en-in/help/118623/how-to-get-the-mac-address-for-an-ethernet-adapter [/URL] IMy current code is [code] .OrderByDescending(n => n.NetworkInterfaceType == NetworkInterfaceType.Ethernet) [/code] but it doesn't give the same address at all times. So, the VC++ code at the above method is considered as the most reliable method to get Mac address of a machine. I have multiple adapters and I want to get the same Mac address all the time. I have written code for a software and I am now coding the licensing part of it and I want to use Mac address in my softwares licensing system and so I need to get the correct Mac address. The C# code which I showed is giving the correct address but not all the times it is same.

@Nitin Sontakke Yes, I have seen that. It uses Management Object and it also doesn't return the right Mac Address that I want to use in my licensing system. The VC++ code which I mentioned works fine but I don't know how to port it to C#.

var myInterfaceAddress = NetworkInterface.GetAllNetworkInterfaces() .Where(n => n.OperationalStatus == OperationalStatus.Up && n.NetworkInterfaceType != NetworkInterfaceType.Loopback) .OrderByDescending(n => n.NetworkInterfaceType == NetworkInterfaceType.Ethernet) .Select(n => n.GetPhysicalAddress()) .FirstOrDefault(); My code was this but this doesn't give the same mac address at all times.

You can do something like this: foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces()) { if (nic.NetworkInterfaceType == NetworkInterfaceType.Ethernet) { nic.GetPhysicalAddress(); } }
