本文告诉大家如何在 dotnet core 获取 Mac 地址
因为在 dotnetcore 是没有直接和硬件相关的,所以无法通过 WMI 的方法获取当前设备的 Mac 地址
但是在 dotnet core 可以使用下面的代码拿到本机所有的网卡地址,包括物理网卡和虚拟网卡

但是可以看到里面有很多不需要使用的网卡,从 堆栈 网找到的方法获取当前有活跃的 ip 的网卡可以通过先判断是不是本地巡回网络等,然后判断有没有网络

foreach (NetworkInterface adapter in nics.Where(c =>
c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up))

获取当前的网卡有没 ip 有 ip 才是需要的

IPInterfaceProperties properties = adapter.GetIPProperties();
var unicastAddresses = properties.UnicastAddresses;
foreach (var temp in unicastAddresses.Where(temp =>
temp.Address.AddressFamily == AddressFamily.InterNetwork))
{
// 这个才是需要的网卡
}

简单输出网卡使用 adapter.GetPhysicalAddress().ToString() 输出,如果需要输出带连接的请使用 GetAddressBytes 然后自己输出
下面的代码是我抽出来的,可以直接使用

上面的方法不仅是在 dotnet core 可以使用,在 dotnet framework 程序同样调用,但是在 dotnet framework 还可以通过 WMI 获取

输出的格式是 5A:15:31:73:B0:9F 同时输出是一个网卡
