C#獲取硬件信息

1. 引用命名空間
   using System.Runtime.InteropServices;
   using System.Management;


取機器名 
public string GetHostName()
{
 return System.Net.Dns.GetHostName();
}

取CPU編號
public String GetCpuID()
{
try
{
   ManagementClass mc = new ManagementClass("Win32_Processor");
   ManagementObjectCollection moc = mc.GetInstances()
   String strCpuID = string.Empty;
   foreach (ManagementObject mo in moc)
   {

  strCpuID = mo.Properties["ProcessorId"].Value.ToString();
  break;

}
   return strCpuID;
}
catch(Exception er)
{

return "";

}
}



取第一塊硬盤編號
public String GetHardDiskID()
{
 try
 {
 ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
 String strHardDiskID = string.Empty;
 foreach (ManagementObject mo in searcher.Get())
 {
     strHardDiskID = mo["SerialNumber"].ToString().Trim();
     break;
 }
 return strHardDiskID;

  }
  catch(Exception er)
  {
 //handle exception
 return "";

  }
}


以下是取得Mac地址
