（一）软件的实现：

SoftReg类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Management;
using System.Text;
using System.Threading.Tasks;namespace WindowsFormsApp16
{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;}}
}

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;using System.Management;    //需要引用System.Management.dll
using Microsoft.Win32;namespace WindowsFormsApp16
{public partial class mainForm : Form{public mainForm(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){}private void mainForm_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();}}}SoftReg softReg = new SoftReg();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 Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace WindowsFormsApp16
{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.Threading.Tasks;namespace WindowsFormsApp17
{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;}}
}

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace WindowsFormsApp17
{public partial class mainForm : Form{public mainForm(){InitializeComponent();}private void mainForm_Load(object sender, EventArgs e){}SoftReg softReg = new SoftReg();private void btnCreate_Click(object sender, EventArgs e){try{string strHardware = this.txtHardware.Text;string strLicence = softReg.GetRNum(strHardware);this.txtLicence.Text = strLicence;}catch (System.Exception ex){MessageBox.Show("输入的机器码格式错误！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);}  }private void btnExit_Click(object sender, EventArgs e){Application.Exit();}}
}
