根据cpu序列号生成注册码的问题。

wfml 2009-04-02 08:58:23

我照着书列子写一个软件注册程序，现在获取到cpu序列号和硬盘序列号了，两个号码组成机器码，通过机器码计算出注册码，可是书上计算注册码的这段我看不懂，最后比较字符串判断注册的函数感觉也有问题。谁能帮忙解释一下？

这里是代码：

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Microsoft.Win32;

using System.Management;

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        // 取得设备硬盘的卷标号

        public string GetDiskVolumeSerialNumber()

        {

            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"d:\"");

            disk.Get();

            return disk.GetPropertyValue("VolumeSerialNumber").ToString();

        }

        private void Form1_Load(object sender, EventArgs e)

        {



        }

        //获得CPU的序列号

        public string getCpu()

        {

            string strCpu = null;

            ManagementClass myCpu = new ManagementClass("win32_Processor");

            ManagementObjectCollection myCpuConnection = myCpu.GetInstances();

            foreach( ManagementObject myObject in myCpuConnection)

            {

                strCpu = myObject.Properties["Processorid"].Value.ToString();

                break;

            }

            return strCpu;

        }

       //生成机器码

        private void button1_Click(object sender, EventArgs e)

            }

            label2.Text = "";

            Random rdid = new Random();

            for (int i = 0; i < 24; i++)//从数组随机抽取24个字符组成新的字符生成机器三

            {

                label2.Text += strid[rdid.Next(0, 24)];

            }

        }

            }

        }
