Get a MAC address in .NETFri, 15 Jul 2011 What to do if you want to get to a machine's MAC address in C# and Microsoft's myriad of classes are tripping you up |
Here's a way to get the local machine's MAC address in C#. Note that there may be various MAC addresses (Ethernet cards, local loopback devices, hooked up 3G devices etc.), so we try to find only the Ethernet MAC address: csharp static string GetMacAddress(){ string macAddresses = ""; foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces()) { // Only consider Ethernet network interfaces, thereby ignoring any // loopback devices etc. if (nic.NetworkInterfaceType != NetworkInterfaceType.Ethernet) continue; if (nic.OperationalStatus == OperationalStatus.Up) { macAddresses += nic.GetPhysicalAddress().ToString(); break; } } return macAddresses; } |
