请教C#取硬盘编号

Question

我在csdn技术中心看到一则示例:...
//取第一块硬盘编号
  public String GetHardDiskID() 
  {
   try
   {
    ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
    String strHardDiskID = null ;
    foreach(ManagementObject mo in searcher.Get()) 
    {    
     strHardDiskID = mo["SerialNumber"].ToString().Trim();
     break;          
    }
    return strHardDiskID ;
   }
   catch
   {
    return "no";
   }
  }//end 
...为什么我运行后,取不取硬盘ID呢?返回的是:"no"?大侠指点迷津!!!

Answer 1

硬盘的ID号分逻辑ID号和物理ID号。逻辑ID号码是硬盘格式化时生成的,而物理ID号是硬盘厂家设定的。你搜索一下summast的blog。他用C++.net封装了一个dll可以调用物理ID号.

Answer 2

c#不能调用到硬盘的物理ID号吗?
大侠指点呀!!!

Answer 3

我这有一个，不过是VB的，我没有测试过，是别人给我的，如果你要，可以Mail，我的是:

Answer 4

WMI服务没启动
大哥,您说详细些呀.谢谢
具体说何操作启动???

我怀疑你的机器是Windows 2000或以下这个Win32_PhysicalMedia仅在XP或以上的机器支持

Answer 9

在  .NET  中通过  WMI  获取物理（非逻辑）硬盘的出厂序列号：using  System;  
using  System.Management;  
 
namespace  ProcessorId  
{  
public  class  Test  
{  
static  void  Main()  
{  
Console.WriteLine("My  harddisk  is  :  "  +  GetHd());  
Console.Read();  
}  
 
public  static  string  GetHd()  
{  
ManagementObjectSearcher  wmiSearcher  =  new  ManagementObjectSearcher();  
 
wmiSearcher.Query  =  new  SelectQuery(  
           "Win32_DiskDrive",    
           "",    
           new  string[]{"PNPDeviceID"}  
           );  
ManagementObjectCollection  myCollection  =  wmiSearcher.Get();  
ManagementObjectCollection.ManagementObjectEnumerator  em  =    
           myCollection.GetEnumerator();  
em.MoveNext();  
ManagementBaseObject  mo  =  em.Current;  
string  id  =  mo.Properties["PNPDeviceID"].Value.ToString().Trim();  
return  id;  
}  
}  
}  

Answer 10

PNPDeviceID 和 磁盘序列号是两码事
