C# 实现软件授权码的功能

对于一个商业软件来说，授权码这个功能必不可少。我这里采用CPU序列号加硬盘标识来判断是否授权。完整代码如下：

using Microsoft.Win32; using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Management; using System.Text; using System.Threading; using System.Threading.Tasks; using System.Windows.Forms; namespace KeyManager { public partial class FrmShouQuan : Form { public FrmShouQuan() { InitializeComponent(); } /// /// 获取CPU的参数 /// /// 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; } /// /// 获取硬盘的参数 /// /// public string GetDiskVolumeSerialNumber() { ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\""); disk.Get(); return disk.GetPropertyValue("VolumeSerialNumber").ToString(); } /// /// 生成机器码，就是CPU参数加上硬盘参数 /// /// /// private void button1_Click(object sender, EventArgs e) { txtMachineInfo.Text = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号 } public int[] intCode = new int[127];//用于存密钥 public void setIntCode() { for (int i = 1; i < intCode.Length; i++) { intCode[i] = i % 10; } } public int[] intNumber = new int[25];//用于存机器码的Ascii值 public char[] Charcode = new char[25];//存储机器码字 //生成注册码 private void button2_Click(object sender, EventArgs e) { if (txtMachineInfo.Text != "") { txtRegistText.Text = GetResistText(txtMachineInfo.Text); } else { MessageBox.Show("请选生成机器码", "注册提示"); } } /// /// 根据机器码获取注册码 /// /// /// private string GetResistText(string machineText) { //把机器码存入数组中 setIntCode();//初始化127位数组 for (int i = 1; i < Charcode.Length; i++)//把机器码存入数组中 { Charcode[i] = Convert.ToChar(machineText.Substring(i - 1, 1)); } for (int j = 1; j < intNumber.Length; j++)//把字符的ASCII值存入一个整数组中。 { intNumber[j] = intCode[Convert.ToInt32(Charcode[j])] + Convert.ToInt32(Charcode[j]); } string strAsciiName = null;//用于存储机器码 for (int j = 1; j < intNumber.Length; j++) { if (intNumber[j] >= 48 && intNumber[j] = 65 && intNumber[j] = 97 && intNumber[j] 122)//判断字符ASCII值是否大于z { strAsciiName += Convert.ToChar(intNumber[j] - 10).ToString(); } else { strAsciiName += Convert.ToChar(intNumber[j] - 9).ToString(); } } } return strAsciiName; } private void btnRegist_Click(object sender, EventArgs e) { if (txtRegistText.Text != "") { if (textBox1.Text.TrimEnd().Equals(txtRegistText.Text.TrimEnd())) { //这里需要将机器码和注册码保存到数据库或注册表中，以便以后校验（推荐保存到数据库中，这样不怕重装系统） MessageBox.Show("注册成功"); } else { MessageBox.Show("注册码输入错误"); } } else { MessageBox.Show("请生成注册码", "注册提示"); } } /// /// 验证是否已经激活软件 /// /// /// private void button4_Click(object sender, EventArgs e) { //这里重新生成机器码和注册码，与数据库中进行对比。只要有一个参数不一致，就是未激活（此处省略两万行代码） } } }

设计文件的代码：

namespace KeyManager { partial class FrmShouQuan { /// /// Required designer variable. /// private System.ComponentModel.IContainer components = null; /// /// Clean up any resources being used. /// /// true if managed resources should be disposed; otherwise, false. protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox();
