C#或者U盘Manufacturer问题?

Question

各位朋友，如何用C#获取U盘的Manufacturer的值呢？U盘的Manufacturer的值在windows下面查看如下:
而我用代码取到的值确为:
Name:Manufacturer  Value:(Standard disk drives)
取Manufacturer的代码如下: ManagementObjectSearcher disks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
                                    foreach (ManagementObject disk in disks.Get())
                                    {
                                        String diskInterface = disk["InterfaceType"] as string;
                                        if ("USB".Equals(diskInterface))
                                        {
                                            StringBuilder sb = new StringBuilder();
                                            foreach (PropertyData data in disk.Properties)
                                            {
                                                sb.Append(data.Name + " | " + data.Value + "\r\n");
                                            }
Console.write(sb.ToString());//这里可以查看到Manufacturer的值，但是值为(Standard disk drives)
                                            String pnpDeviceId = disk["PNPDeviceID"] as String;  
                                        }
                                    }最后我取出来了pnpDeviceId 的值USBSTOR\DISK&VEN_SANDISK&PROD_DATA&REV_PMAP\20CF30E118F8ED31720E0190&0
,其中有一个VEN，不知道是不是微软的Manufacturer也是根据这个VEN_后面的值来提取出来的？各位有办法直接取出和系统显示一样的Manufacturer值吗？u盘ManufacturerPNPDeviceID

你的代码我早就试过了，不行，得出来和我的结果是一样的(Standard disk drives)。
