C# 软件注册和注册机
（一）软件的实现：
SoftReg类：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Management; //需要引用System.Management.dll namespace SoftRegister { class SoftReg { ///<summary> /// 获取硬盘卷标号 ///</summary> ///<returns></returns> public string GetDiskVolumeSerialNumber() { ManagementClass mc = new ManagementClass("win32_NetworkAdapterConfiguration"); ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\""); disk.Get(); return disk.GetPropertyValue("VolumeSerialNumber").ToString(); } ///<summary> /// 获取CPU序列号 ///</summary> ///<returns></returns> public string GetCpu() { string strCpu = null; ManagementClass myCpu = new ManagementClass("win32_Processor"); ManagementObjectCollection myCpuCollection = myCpu.GetInstances(); foreach (ManagementObject myObject in myCpuCollection) { strCpu = myObject.Properties["Processorid"].Value.ToString(); } return strCpu; } ///<summary> /// 生成机器码 ///</summary> ///<returns></returns> public string GetMNum() { string strNum = GetCpu() + GetDiskVolumeSerialNumber(); string strMNum = strNum.Substring(0, 24); //截取前24位作为机器码 return strMNum; } public int[] intCode = new int[127]; //存储密钥 public char[] charCode = new char[25]; //存储ASCII码 public int[] intNumber = new int[25]; //存储ASCII码值 //初始化密钥 public void SetIntCode() { for (int i = 1; i < intCode.Length; i++) { intCode[i] = i % 9; } } ///<summary> /// 生成注册码 ///</summary> ///<returns></returns> public string GetRNum() { SetIntCode(); string strMNum = GetMNum(); for (int i = 1; i < charCode.Length; i++) //存储机器码 { charCode[i] = Convert.ToChar(strMNum.Substring(i - 1, 1)); } for (int j = 1; j < intNumber.Length; j++) //改变ASCII码值 { intNumber[j] = Convert.ToInt32(charCode[j]) + intCode[Convert.ToInt32(charCode[j])]; } string strAsciiName = ""; //注册码 for (int k = 1; k < intNumber.Length; k++) //生成注册码 { if ((intNumber[k] >= 48 && intNumber[k] <= 57) || (intNumber[k] >= 65 && intNumber[k] <= 90) || (intNumber[k] >= 97 && intNumber[k] <= 122)) //判断如果在0-9、A-Z、a-z之间 { strAsciiName += Convert.ToChar(intNumber[k]).ToString(); } else if (intNumber[k] > 122) //判断如果大于z { strAsciiName += Convert.ToChar(intNumber[k] - 10).ToString(); } else { strAsciiName += Convert.ToChar(intNumber[k] - 9).ToString(); } } return strAsciiName; } } }
主窗体：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Microsoft.Win32; namespace SoftRegister { public partial class FormMain : Form { public FormMain() { InitializeComponent(); } SoftReg softReg = new SoftReg(); private void FormMain_Load(object sender, EventArgs e) { //判断软件是否注册 RegistryKey retkey = Registry.CurrentUser.OpenSubKey("SOFTWARE", true).CreateSubKey("mySoftWare").CreateSubKey("Register.INI"); foreach (string strRNum in retkey.GetSubKeyNames()) { if (strRNum == softReg.GetRNum()) { this.labRegInfo.Text = "此软件已注册！"; this.btnReg.Enabled = false; return; } } this.labRegInfo.Text = "此软件尚未注册！"; this.btnReg.Enabled = true; MessageBox.Show("您现在使用的是试用版，可以免费试用30次！", "信息", MessageBoxButtons.OK, MessageBoxIcon.Information); Int32 tLong; //已使用次数 try { tLong = (Int32)Registry.GetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\mySoftWare", "UseTimes", 0); MessageBox.Show("您已经使用了" + tLong + "次！", "信息", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch { MessageBox.Show("欢迎使用本软件！", "信息", MessageBoxButtons.OK, MessageBoxIcon.Information); Registry.SetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\mySoftWare", "UseTimes", 0, RegistryValueKind.DWord); } //判断是否可以继续试用 tLong = (Int32)Registry.GetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\mySoftWare", "UseTimes", 0); if (tLong < 30) { int tTimes = tLong + 1; Registry.SetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\mySoftWare", "UseTimes", tTimes); } else { DialogResult result = MessageBox.Show("试用次数已到！您是否需要注册？", "信息", MessageBoxButtons.YesNo, MessageBoxIcon.Information); if (result == DialogResult.Yes) { FormRegister.state = false; //设置软件状态为不可用 btnReg_Click(sender, e); //打开注册窗口 } else { Application.Exit(); } } } private void btnClose_Click(object sender, EventArgs e) { Application.Exit(); } private void btnReg_Click(object sender, EventArgs e) { FormRegister frmRegister = new FormRegister(); frmRegister.ShowDialog(); } } }
注册窗体：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Microsoft.Win32; namespace SoftRegister { public partial class FormRegister : Form { public FormRegister() { InitializeComponent(); } public static bool state = true; //软件是否为可用状态 SoftReg softReg = new SoftReg(); private void btnReg_Click(object sender, EventArgs e) { try { if (txtLicence.Text == softReg.GetRNum()) { MessageBox.Show("注册成功！重启软件后生效！", "信息", MessageBoxButtons.OK, MessageBoxIcon.Information); RegistryKey retkey = Registry.CurrentUser.OpenSubKey("Software", true).CreateSubKey("mySoftWare").CreateSubKey("Register.INI").CreateSubKey(txtLicence.Text); retkey.SetValue("UserName", "Rsoft"); this.Close(); } else { MessageBox.Show("注册码错误！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning); txtLicence.SelectAll(); } } catch (Exception ex) { throw new Exception(ex.Message); } } private void btnClose_Click(object sender, EventArgs e) { if (state == true) { this.Close(); } else { Application.Exit(); } } private void FormRegister_Load(object sender, EventArgs e) { this.txtHardware.Text = softReg.GetMNum(); } } }
（二）注册机的实现：
SoftReg类：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Management; namespace SoftwarePassport { class SoftReg { public int[] intCode = new int[127]; //存储密钥 public char[] charCode = new char[25]; //存储ASCII码 public int[] intNumber = new int[25]; //存储ASCII码值 //初始化密钥 public void SetIntCode() { for (int i = 1; i < intCode.Length; i++) { intCode[i] = i % 9; } } ///<summary> /// 生成注册码 ///</summary> ///<returns></returns> public string GetRNum(string strMNum) { SetIntCode(); for (int i = 1; i < charCode.Length; i++) //存储机器码 { charCode[i] = Convert.ToChar(strMNum.Substring(i - 1, 1)); } for (int j = 1; j < intNumber.Length; j++) //改变ASCII码值 { intNumber[j] = Convert.ToInt32(charCode[j]) + intCode[Convert.ToInt32(charCode[j])]; } string strAsciiName = ""; //注册码 for (int k = 1; k < intNumber.Length; k++) //生成注册码 { if ((intNumber[k] >= 48 && intNumber[k] <= 57) || (intNumber[k] >= 65 && intNumber[k] <= 90) || (intNumber[k] >= 97 && intNumber[k] <= 122)) //判断如果在0-9、A-Z、a-z之间 { strAsciiName += Convert.ToChar(intNumber[k]).ToString(); } else if (intNumber[k] > 122) //判断如果大于z { strAsciiName += Convert.ToChar(intNumber[k] - 10).ToString(); } else { strAsciiName += Convert.ToChar(intNumber[k] - 9).ToString(); } } return strAsciiName; } } }
