    How to use WMI to get info provided in STORAGE_DEVICE_DESCRIPTOR structure
    I have C++ code that I am converting to C#. The C++ code uses the following code
    status = DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY,
    &query, sizeof(STORAGE_PROPERTY_QUERY),
    &buf, 512, &length, NULL);
    if ( status )
    {
    PSTORAGE_DEVICE_DESCRIPTOR device = (PSTORAGE_DEVICE_DESCRIPTOR)buf;
    media.Bus = BusType[device->BusType];
    media.DeviceType = device->DeviceType;
    media.Removable = (bool)device->RemovableMedia;
    if (device->VendorIdOffset)
    media.Vendor = &buf[device->VendorIdOffset];
    else
    media.Vendor = BusType[0]; //unknown
    if (device->ProductIdOffset)
    media.Product = &buf[device->ProductIdOffset];
    else
    media.Product = BusType[0]; //unknown
    if (device->ProductRevisionOffset)
    media.Revision = &buf[device->ProductRevisionOffset];
    else
    media.Revision = BusType[0]; //unknown
    if (device->SerialNumberOffset)
    media.SerialNum = &buf[device->SerialNumberOffset];
    else
    media.SerialNum = BusType[0]; //unknown

    After much thought I have decided that it would be better to use WMI in the new code instead of trying to "PInvoke" the Win32 API calls. I can not find any equivalent in the WMI world to get values like VendorID offset, BusType, SerialNumber offse.

    Can anyone offer any help?
