Question

我需要在Metro UI应用中获取网络接口的MAC地址。据我所知，.NET 4.5 for Metro应用程序API根本不支持这一点。我错了吗？

Answer 1

您无法检索每个说法的MAC地址，但您可以检索硬件特定信息以识别计算机。

这是一篇完整的msdn文章，讨论主题：Guidance on using the App Specific Hardware ID (ASHWID) to implement per-device app logic (Windows)

小心只使用您需要的信息而不是完整的ID，因为它可能会根据您无用的信息（例如Dock Station字节）而改变。

以下是基于几个字节（CPU ID，内存大小，磁盘设备序列号和BIOS）的计算设备ID的代码示例：

string deviceSerial = string.Empty;
// http://msdn.microsoft.com/en-us/library/windows/apps/jj553431
Windows.System.Profile.HardwareToken hardwareToken = Windows.System.Profile.HardwareIdentification.GetPackageSpecificToken(null);
using (DataReader dataReader = DataReader.FromBuffer(hardwareToken.Id))
{
    int offset = 0;
    while (offset < hardwareToken.Id.Length)
    {
        byte[] hardwareEntry = new byte[4];
        dataReader.ReadBytes(hardwareEntry);

        // CPU ID of the processor || Size of the memory || Serial number of the disk device || BIOS
        if ((hardwareEntry[0] == 1 || hardwareEntry[0] == 2 || hardwareEntry[0] == 3 || hardwareEntry[0] == 9) && hardwareEntry[1] == 0)
        {
            if (!string.IsNullOrEmpty(deviceSerial))
            {
                deviceSerial += "|";
            }
            deviceSerial += string.Format("{0}.{1}", hardwareEntry[2], hardwareEntry[3]);
        }
        offset += 4;
    }
}

Debug.WriteLine("deviceSerial=" + deviceSerial);

Answer 2

您无法从Metro风格应用程序访问低级别网络信息，因此使用股票SDK 。这是设计的。

Answer 3

    private void getDeviceInfos()
    {
        Profiles = Windows.Networking.Connectivity.NetworkInformation.GetConnectionProfiles();
        Adapter = Profiles[0].NetworkAdapter;

        Guid AdapterId = Adapter.NetworkAdapterId;
    }
    IReadOnlyList<Windows.Networking.Connectivity.ConnectionProfile> Profiles;
    Windows.Networking.Connectivity.NetworkAdapter Adapter;

可以在.NET Metro应用程序中获取网络MAC地址吗？
