.net 怎样检测详细硬件信息？

[shine]

wmi获取的信息不全面，比如硬盘序列号就取不到，有的只是“修订号”（HWINFO32上显示的是“revision”）。
这些都没有关系，关键是获取不了内存的详细信息。比如：内存条数量，每条内存的容量、速度。有的只是可用物理内存总数（也就是除了显存之后的物理内存总数）。

有什么办法可以获得硬盘序列号、内存条数量，每条内存的容量、频率？
那些硬件检测软件都可以很详细地检测到，.net可以吗？怎么做？

在.net环境下（用ＶＣ＃描述）获取机器的硬件信息，要用到一个类库（System.Management.dll）,在解决方案资源管理器中添加System.Management 即可
　　我们可以将该程序编译成.dll文件，便于以后调用；
　　在程序代码中进行引用 using System.Management;
　　具体 代码为:
　　1.获取机器名：
　　public string GetHostName()
　　 {
　　 return System.Net.Dns.GetHostName();
　　 }
　　２.获取ＣＰＵ编号
　　public string GetCpuId()
　　 {
　　 ManagementClass mc = new ManagementClass("Win32_Processor");
　　 ManagementObjectCollection moc = mc.GetInstances();
　　
　　 String strCpuID = null ;
　　 foreach( ManagementObject mo in moc )
　　 {
　　 strCpuID = mo.Properties["ProcessorId"].Value.ToString();
　　 break;
　　 }
　　 return strCpuID;
　　 }
　　3.获取主硬盘编号
　　public string GetMainHardDiskId()
　　{
　　 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 ;
　　}
　　4.获取bios和mac地址，这个有点复杂，需要用到NETAPI32.DLL

我终于搞明白了，win2000里得不出我想要的那些东西，xp里就可以。
包括硬盘序列号、内存条数量，内存条容量。
不过内存类型（如sdram\ddr\ddr2）、频率也没有。wmi规范里有说明内存类型的字段的，但是xp试过不行。
另外，我觉得可以通过模拟写/读操作来计算频率。

硬盘序列号还是不要考虑了吧，因为不是所有硬盘都能取到序列号的，另外硬盘的序列号的长度也不相同

至少能获得物理内存总数（含动态显存）也好啊。

my命名空间。
my.computer吧。有一些获取硬件信息函数和类
告诉告诉你一个源码。。柳善居有这样的一个源码。还不错。
搜柳善居可以搜到。
