我正在尝试从计算机检索板载以太网适配器的MAC地址，以便为设备生成唯一标识符。以下是我正在使用的方法。
NetworkInterface[] ifConfig = NetworkInterface.GetAllNetworkInterfaces();
int maxHash = int.MinValue;
Guid D = Guid.Empty;
foreach (NetworkInterface net in ifConfig)
{
if (net.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
{
if (maxHash < net.GetPhysicalAddress().ToString().GetHashCode())
{
maxHash = net.GetPhysicalAddress().ToString().GetHashCode();
ID = new Guid(String.Concat("00000000-0000-0000-0000-", net.GetPhysicalAddress().ToString()));
}
}
}
但是，蓝牙适配器，VM适配器和其他几个网络适配器也属于NetworkInterfaceType.Ethernet类型。如何专门获取板载以太网连接的MAC地址？
执行包含以省略那些是不可能的。任何帮助将不胜感激。

我最近编写了一个 Powershell 脚本，用于为 Windows PC 生成一个永久性的系统格式不可变的唯一 ID，用于库存目的（对 ID 进行 QR 编码，将其打印在贴纸上......）。
它将 PC 制造商 UUID 字段与每个连接 PCI 的网络适配器的永久 MAC 地址连接起来（按 MAC 字母顺序排序）。 PCI 要求会自动取消可移动或虚拟 NIC。真正的脚本 MD5 对结果字符串进行哈希处理以获得更同质的标识符（恒定长度和 0-9A-F 符号集），但为了简单起见，我将在此处省略这一点
我本可以选择 PC 制造商 UUID 并收工，但我对依赖于以下内容的 ID 感到不舒服：
基本上，我试图坚持将尽可能多的具有永久和“唯一”（梦想中）标识符的不可拆卸组件放入混音器的直观想法。
此 ID 生成技术不是防故障的：如果向系统添加新的 PCI 网络适配器，ID 将更改。但随着集成 NIC 的普及，我相信这不再需要担心，如果曾经是的话。
这个解决方案并不直接适用于 C#，但我相信它可以很容易地适应，因为 Powershell 共享几乎相同的 .net 对象类生态系统。
#Variable names in spanish, but if I try to translate them in a hurry
#I will most certainly end up with a non-working script
$elpc=(Get-WmiObject -Class Win32_ComputerSystemProduct)
$id=$elpc.UUID #This is the UUID the manufacturer wrote somewhere in the BIOS
#Get network devices
#"Net" for network devices, "PCI*" because PCI connected devices begin that way
$dispositivosdered=@(Get-PnpDevice | Where-Object {($_.Class -eq "Net") -and ($_.InstanceId -like "PCI*")})
#Get network adapters
#Use "PermanentAddress" property. "MacAddress" property can be spoofed easily
$tarjetasdered=@(Get-Netadapter | Sort-Object PermanentAddress)
#Double loop to rule out any network adapters which are not PCI
#Comparison is made using long name, ie "Realtek PCIe GBE Family Controller #2"
#Is the only valid field I found to (inner) join the device and adapter worlds
for($j=0; $j -lt $tarjetasdered.length; $j++) {
for ($i=0; $i -lt $dispositivosdered.length; $i++) {
if($dispositivosdered[$i].FriendlyName -eq $tarjetasdered[$j].InterfaceDescription) {
if(-not [string]::IsNullOrEmpty($tarjetasdered[$j].PermanentAddress)) {
$id= $id + $tarjetasdered[$j].PermanentAddress.Replace("-", "");
}
}
}
