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
