问题描述

I'd like to be able to read the mac address from the first active network adapter using VB.net or C# (using .NET 3.5 SP1) for a winform application

推荐答案

由于NET 2.0也一直在给你这些信息的System.Net.NetworkInformation命名空间NetworkInterface类。试试这个：

Since .Net 2.0 there's been a NetworkInterface class in the System.Net.NetworkInformation namespace that will give you this information. Try this:

        foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
        {
            if (nic.OperationalStatus == OperationalStatus.Up)
            {
                Console.WriteLine(nic.GetPhysicalAddress().ToString());
                break;
            }
        }
