C#获取机器码的方法详解(机器名,CPU编号,硬盘编号,网卡mac等)

本文实例讲述了C#获取机器码的方法。分享给大家供大家参考，具体如下：

using System.Runtime.InteropServices;
using System.Management;
using System;
public class HardwareInfo
{
  //取机器名
  public string GetHostName()
  {
  return System.Net.Dns.GetHostName();
  }
  //取CPU编号
  public String GetCpuID()
  {
    try
    {
      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;
    }
    catch
    {
      return "";
    }
  }//end method
//取第一块硬盘编号
  public String GetHardDiskID()
  {
    try
    {
      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 ;
    }
    catch
    {
      return "";
    }
  }//end
