如何获取硬盘的序列号，C#中是否有好的方法

我希望得到物理磁盘的序列号，可是有的机器能得到这个序列号，有的机器却不能
还有就是不知道移动硬盘的序列号不知道是否可以通过C#得到

Answer 1

得用WMI吧

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 2

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
String strHardDiskID = null ;
foreach(ManagementObject mo in searcher.Get())
{
strHardDiskID = mo["SerialNumber"].ToString().Trim();
MessageBox.Show(strHardDiskID);
}
