硬盘序列号

Question

我用wmi获取pnpdevieID是IDE\DISKST3160215AS_____________________________4.AAB___\5&B140DE0&0&0.0.0 
而我用Dos获得的硬盘序列号是46EB-C82F
请问这是为什么呀，哪个是正确的，哪个是唯一的；若不正确，怎样获得正确的序列号？
请各位大侠出手相助啊！！！

Answer 1

try
            {
                ManagementClass mc = new ManagementClass("Win32_DiskDrive");
                ManagementObjectCollection moc = mc.GetInstances();                foreach (ManagementObject mo in moc)
                        foreach (PropertyData property in mo.Properties)
                        {
                            Console.Write(property.Name + " --- ");
                            try
                            {
                                Console.WriteLine(mo.Properties[property.Name].Value.ToString());
                            }
                            catch
                            {
                                Console.WriteLine();
                            }
                        }
                }执行上面这段代码,系统中所有硬盘中所有的东西都读出来了.要哪个取哪个.

/// <summary>
        /// 硬盘序列号。
        /// </summary>
        public static string HardDiskID
        {
            get
            {
                if(String.IsNullOrEmpty(_hardDiskID))
                {
                    try
                    {
                        string filename = System.IO.Path.Combine(FileUtil.AppDir, "harddisk.txt");
                        System.IO.StreamWriter writer = new System.IO.StreamWriter(filename, false);
                        ManagementClass cimobject = new ManagementClass("Win32_DiskDrive");
                        ManagementObjectCollection moc = cimobject.GetInstances();
                        foreach (ManagementObject mo in moc)
                        {
                            foreach (PropertyData property in mo.Properties)
                            {
                                writer.WriteLine("{0} = {1};", property.Name, property.Value);
#if DEBUG
                                Console.WriteLine("{0} = {1};", property.Name, property.Value);
#endif
                            }
                            _hardDiskID = (string)mo.Properties["SerialNumber"].Value;
                            if (!string.IsNullOrEmpty(_hardDiskID) && !IsException)
                            {
                                writer.Close();
                                System.IO.File.Delete(filename);
                                break;
                            }
                            mo.Dispose();
                        }
                        writer.Close();
                        moc.Dispose();
                    }
                    catch //(Exception ex)
                    {
                    }
                }
                return _hardDiskID;
            }
        }我用这个代码是好的呀，你是不是参数写错了？你用的是哪个参数读到的？
