Win32_PhysicalMedia不会为Windows 7返回一致/相同的硬盘序列号 [英] Win32_PhysicalMedia not returning consistent/same Hard Disk Serial Number for Windows 7

问题描述

我正在Windows 7中使用Win32_PhysicalMedia读取硬盘序列号.通常它返回错误的序列号.此问题不一致.

i am using Win32_PhysicalMedia in windows 7 for reading the Hard Disk Serial Number. Often it returns the wrong serial number.This problem is inconsistent .

仅在很少的Windows 7计算机中会出现此问题.

This problem arises only in few Windows 7 machine.

对于Windows XP，相同的逻辑总是可以正常工作.

The same logic always works fine for Windows XP.

我使用的代码段如下:-

the code snippet, which i have used is below :-

 

          字符串键="Win32_PhysicalMedia";
           ManagementObjectSearcher搜索程序=新的ManagementObjectSearcher("从" +键中选择*);
          字符串SerialNumber = string.Empty;

          试试
           {
                            字符串项目= string.Empty;
                             foreach(ManagementObject在searcher.Get()中的共享)
                             {
                   如果(share.Properties.Count< = 0)
                    {
               b返回"；
                    }

                    object SerNumber = share ["SerialNumber"];
                   如果(SerNumber！= null)
                    {
               b SerialNumber = share ["SerialNumber"].ToString().Trim();
               b休息；
                    }


                    //foreach(共享的PropertyDataPC.Properties)
                    //{
                    //    if(PC！= null&& PC.Value！= null)
                    //    {
                    //       item = PC.Name;
                    //       if(item =="SerialNumber")
                    //       {
                    //            SerialNumber = SerialNumber +(PC.Value.ToString()).Trim();
                    //       }
                    //    }

                    //}
                             }

            string Key = "Win32_PhysicalMedia";
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);
            string SerialNumber = string.Empty;

            try
            {
                string item = string.Empty;
                foreach (ManagementObject share in searcher.Get())
                {
                    if (share.Properties.Count <= 0)
                    {
                        return "";
                    }

                    object SerNumber = share["SerialNumber"];
                    if (SerNumber != null)
                    {
                        SerialNumber = share["SerialNumber"].ToString().Trim();
                        break;
                    }


                    //foreach (PropertyData PC in share.Properties)
                    //{
                    //    if (PC != null && PC.Value != null)
                    //    {
                    //        item = PC.Name;
                    //        if (item == "SerialNumber")
                    //        {
                    //            SerialNumber = SerialNumber + (PC.Value.ToString()).Trim();
                    //        }
                    //    }

                    //}
                }

 

该代码一读取一个序列号(或第一个序列号)，便立即存在.

As soon as the code read a Serial Number ( or First Serial Number) , it exists.

 

在这方面请提供帮助.
