我正在开发一个 Windows 10 通用应用程序，我需要获取运行通用应用程序的设备的网络适配器的 mac 地址。我看了一点 MSDN，但我找到了获取 mac 地址的方法，谁能帮我提供代码以获取 windows 10 通用应用程序中网络适配器的 mac 地址？
提前致谢。

嗯，我写了一些东西，但我没有在移动设备上测试它，因为我目前没有，但我在我的 PC 和 Windows Mobile 10 模拟器上测试了它。
public static class AdaptersHelper

const int MAX_ADAPTER_DESCRIPTION_LENGTH = 128;

const int MIB_IF_TYPE_OTHER = 1;

long structSize = Marshal.SizeOf(typeof(IP_ADAPTER_INFO));
IntPtr pArray = Marshal.AllocHGlobal(new IntPtr(structSize));
int ret = GetAdaptersInfo(pArray, ref structSize);
if (ret == ERROR_BUFFER_OVERFLOW) // ERROR_BUFFER_OVERFLOW == 111
{
// Buffer was too small, reallocate the correct size for the buffer.
pArray = Marshal.ReAllocHGlobal(pArray, new IntPtr(structSize));

if (ret == 0)

while (pEntry != IntPtr.Zero);
Marshal.FreeHGlobal(pArray);
}
else
{
Marshal.FreeHGlobal(pArray);
throw new InvalidOperationException("GetAdaptersInfo failed: " + ret);
}
return adapters;
}
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct IP_ADAPTER_INFO
{
public IntPtr Next;
public Int32 ComboIndex;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = MAX_ADAPTER_NAME_LENGTH + 4)]
public string AdapterName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = MAX_ADAPTER_DESCRIPTION_LENGTH + 4)]

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct IP_ADDRESS_STRING
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 16)]
public string Address;
}
}
还有我的 AdapterInfo 类：
public class AdapterInfo
{
public string Type { get; set; }
public string Description { get; set; }
public string Name { get; set; }
public string MAC { get; set; }
}

引自 MSDN Fourms 帖子“How can a Windows Store App access the MAC addresses of network adapter devices”
通常，您无法通过设计从 Windows 应用商店应用获取系统特定信息。
支持一种特殊情况：Guidance on using the App Specific Hardware ID (ASHWID) to implement per-device app logic

我知道这是一篇旧帖子，但对于新的冒险，此代码适用于 UWP x86 和 ARM（在 raspberry 3 上测试）
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;
}
