C#获取硬件信息

1. 引用命名空间
   using System.Runtime.InteropServices;
   using System.Management;
 
2. 取机器名
public string GetHostName()
{
    return System.Net.Dns.GetHostName();
}
 
3. 取CPU编号
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 "";
   }
}
 
 
4. 取第一块硬盘编号
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 "";
     }
}
 
 
5. 以下是取得Mac地址
