如何用c#做一个获取硬盘物理id 并且修改 物理id 的程序

参考：
Get Hard Drive model
ManagementObjectSearcher searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

foreach(ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd = new HardDrive();
hd.Model = wmi_HD["Model"].ToString();
hd.Type = wmi_HD["InterfaceType"].ToString();
hdCollection.Add(hd);
}

Get the Serial Number
searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

int i = 0;
foreach(ManagementObject wmi_HD in searcher.Get())
{
// get the hard drive from collection
// using index
HardDrive hd = (HardDrive)hdCollection[i];

// get the hardware serial no.
if (wmi_HD["SerialNumber"] == null)
hd.SerialNo = "None";
else
hd.SerialNo = wmi_HD["SerialNumber"].ToString();

++i;
}
