c# 软件注册机
一、创建生成机器码的类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;//添加引用注册表
namespace DisDemo
{
internal class SoftRegs
{
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;
}
}
}
二、创建生成机器码窗体
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 DisDemo
{
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();
Environment.Exit(0);
}
}
private void FormRegister_Load(object sender, EventArgs e)
{
this.txtHardware.Text = softReg.GetMNum();
}
}
}
三、主窗体判断是否注册
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();
}
}
}
四、创建生成注册码类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;//添加引用
namespace DisDemo
{
internal class SoftRegs
{
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;
}
}
}
五、创建注册码窗体
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;
namespace DisDemo
{
public partial class zhuce : Form
{
SoftRegs softReg = new SoftRegs();
public zhuce()
{
InitializeComponent();
}
private void btnReg_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 btnClose_Click(object sender, EventArgs e)
{
Application.Exit();
}
}
}
