软件开发过程中经常需要获取CPU序列号、MAC序列号或者硬盘ID等系统信息，在给软件加序列号时这三个应该是最有用的，可以实现序列号和机器绑定，用于保护软件。下面看一下使用C#如何获取。

using System;
using System.Management; 

///Computer Information 
public class Computer 
{ 
	public string CpuID; 				//1.cpu序列号
	public string MacAddress; 			//2.mac序列号
   	public string DiskID; 				//3.硬盘id
    public string IpAddress; 			//4.ip地址
    public string LoginUserName; 		//5.登录用户名
    public string ComputerName; 		//6.计算机名
    public string SystemType;			//7.系统类型
    public string TotalPhysicalMemory; //8.内存量 单位：M

	//构造函数
	public Computer() 
    { 
		CpuID = GetCpuID();
        MacAddress = GetMacAddress();
        DiskID = GetDiskID(); 

        IpAddress = GetIPAddress();
        LoginUserName = GetUserName();
        SystemType = GetSystemType(); 

        TotalPhysicalMemory = GetTotalPhysicalMemory();

    }
