获取计算机中的硬件信息
在项目开发过程中，经常会需要读取所在计算机的硬件信息，包括CPU的序列号，主板的序列号，硬盘的序列号，MAC地址，IP地址，用户名，系统类型，计算机名称，操作系统类型，物理内存大小，BIOS内容等。
开发环境：VS2005 .NET2.0
项目工程文件：Computer.zip
/*****************************************************************/
/* 作者：虞晓杰
* Emial：fishyxj@sina.com
* 2011.9.26
* 功能：用于获取计算机的各种信息，包括CPU的ID，MAC地址，硬盘ID，
* IP地址登录用户名，计算机名称，系统类型，物理内存，主板的ID，
* BIOS的ID
*
* 缺陷：当计算机存在虚拟网卡时，无法区分虚拟网卡与真实网卡，因此
* 读取MAC地址时，会存在不稳定的情况。需要自行处理虚拟网卡MAC的情
* 况
