如何在C#中读取USB(PnP)设备的WMI数据,在本例中是硬件ID?

    如何从USB设备获取硬件id?我知道如何通过设备管理器获取该id,但我想通过C#获取。这可能吗?这是我已经做过的,但如果硬件由供应商id(VID)和产品id(PID)组成,那么它不会给我带来硬件: 

    ManagementObjectSearcher USB = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'");
ManagementObjectCollection USBinfo = USB.Get();

foreach (ManagementObject MO in USBinfo)
{
    serialNumber = (string)MO["DeviceID"];
    name = (string)MO["Name"];
    Drives.Add(new KeyValuePair<String, String>(name, serialNumber));
}

    我还用“PNPDeviceID”和“SerialNumber”代替“DeviceID”尝试了它,但这也没有回复我需要的硬件id。

    原始答案 (见下面更新的答案)

    你需要看看 Win32_PnPEntity WMI类。根据上述描述,你可以看到,你只需要检查 HardwareID .

    下面的代码显示了以一种“快速而肮脏”的方式,我建议创建一个 Win32_PnpEntity 类,该类通过属性公开数据。 

    ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_PnPEntity");
ManagementObjectCollection deviceCollection = searcher.Get();

foreach (var device in deviceCollection)
{
    try
    {
        string caption = (string)device.GetPropertyValue("Caption");

        if (caption == null)
            continue;

        Console.WriteLine(caption);

        string[] hardwareIDs = (string[])device.GetPropertyValue("HardwareID");

        if (hardwareIDs == null)
            continue;

        foreach (string hardwareID in hardwareIDs)
        {
            Console.WriteLine(hardwareID);
        }

        Console.WriteLine();
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
    }
}

    更新的答案

    一般问题是 如何在C#中读取USB(PnP)设备的WMI数据,在这种情况下是硬件ID? ,我写了一篇 Win32_Pnp实体 类(删除评论,因为帖子限制在30000个字符以内?如果有人想要评论版本,请给我一行) ManageementBasObject 并提供该给定实体的所有数据作为属性。

    用法: 

    ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_PnPEntity");
ManagementObjectCollection deviceCollection = searcher.Get();

foreach (var entity in deviceCollection)
{
    Win32_PnPEntity device = new Win32_PnPEntity(entity);

    Console.WriteLine($"Caption: {device.Caption}");
    Console.WriteLine($"Description: {device.Description}");
    Console.WriteLine($"Number of hardware IDs: {device.HardwareID.Length}");

    foreach (string hardwareID in device.HardwareID)
    {
        Console.WriteLine(hardwareID);
    }

    Console.WriteLine();
}

    这个 Win32_Pnp实体 类别:
