C# 给软件加注册码功能
为自己写的程序加一个注册功能吧。生成的机器号是根据CPU和硬盘号来的,根据自己的需求改成是否是随机生成。 代码直接粘贴到新建类覆盖原代码就能直接用了。 using System; using System.Management; using System.Security.Cryptography; using System.Text; namespace RegisterClass { class RegisterClass { //步骤一: 获得CUP序列号和硬盘序列号的实现代码如下: //获得CPU的序列号 bool Stupids = true; bool Cat = false; 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; } //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=\"c:\""); disk.Get(); return disk.GetPropertyValue("VolumeSerialNumber").ToString(); } //步骤二: 收集硬件信息生成机器码, 代码如下: //生成机器码 public string CreateCode() { string temp = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号 string[] strid = new string[24];// for (int i = 0; i < 24; i++)//把字符赋给数组 { strid[i] = temp.Substring(i, 1); } temp = ""; //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 { //temp += strid[rdid.Next(0, 24)]; temp += strid[i+3>=24?0:i+3]; } return GetMd5(temp); } //步骤三: 使用机器码生成软件注册码, 代码如下: //使用机器码生成注册码 public int[] intCode = new int[127];//用于存密钥 public void setIntCode()//给数组赋值个小于10的随机数 { //Random ra = new Random(); //for (int i = 1; i < intCode.Length;i++ ) //{ // intCode[i] = ra.Next(0, 9); //} for (int i = 1; i < intCode.Length; i++) { intCode[i] = i + 3 > 9 ? 0 : i + 3; } } 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 public string GetCode(string code) { if (code != "") { //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(code.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++) { //MessageBox.Show((Convert.ToChar(intNumber[j])).ToString()); //判断字符ASCII值是否0-9之间 if (intNumber[j] >= 48 && intNumber[j] <= 57) { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } //判断字符ASCII值是否A-Z之间 else if (intNumber[j] >= 65 && intNumber[j] <= 90) { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } //判断字符ASCII值是否a-z之间 else if (intNumber[j] >= 97 && intNumber[j] <= 122) { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else//判断字符ASCII值不在以上范围内 { if (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(); } } //label3.Text = strAsciiName;//得到注册码 } return strAsciiName; } else { return ""; } } //步骤四: 用户输入注册码注册软件, 演示代码如下: //注册 public bool RegistIt(string currentCode,string realCode) { if (realCode != "") { if (currentCode.TrimEnd().Equals(realCode.TrimEnd())) { Microsoft.Win32.RegistryKey retkey = Microsoft.Win32.Registry.CurrentUser. OpenSubKey("software", true).CreateSubKey("StupidsCat"). CreateSubKey("StupidsCat.ini"). CreateSubKey(currentCode.TrimEnd()); retkey.SetValue("StupidsCat", "BBC6D58D0953F027760A046D58D52786"); retkey = Microsoft.Win32.Registry.LocalMachine. OpenSubKey("software", true).CreateSubKey("StupidsCat"). CreateSubKey("StupidsCat.ini"). CreateSubKey(currentCode.TrimEnd()); retkey.SetValue("StupidsCat", "BBC6D58D0953F027760A046D58D52786"); return Stupids; } else { return Cat; } } else { return Cat; } } public bool BoolRegist(string sn) { string[] keynames; bool flag = false; Microsoft.Win32.RegistryKey localRegKey = Microsoft.Win32.Registry.LocalMachine; Microsoft.Win32.RegistryKey userRegKey = Microsoft.Win32.Registry.CurrentUser; try { keynames = localRegKey.OpenSubKey("software\\StupidsCat\\StupidsCat.ini\\" + GetMd5(sn)).GetValueNames(); foreach (string name in keynames) { if (name == "StupidsCat") { if (localRegKey.OpenSubKey("software\\StupidsCat\\StupidsCat.ini\\" + GetMd5(sn)).GetValue("StupidsCat").ToString() == "BBC6D58D0953F027760A046D58D52786") flag = true; } } keynames = userRegKey.OpenSubKey("software\\StupidsCat\\StupidsCat.ini\\" + GetMd5(sn)).GetValueNames(); foreach (string name in keynames) { if (name == "StupidsCat") { if (flag && userRegKey.OpenSubKey("software\\StupidsCat\\StupidsCat.ini\\" + GetMd5(sn)).GetValue("StupidsCat").ToString() == "BBC6D58D0953F027760A046D58D52786") return true; } } return false; } catch { return false; } finally { localRegKey.Close(); userRegKey.Close(); } } public string GetMd5(object text) { string path = text.ToString(); MD5CryptoServiceProvider MD5Pro = new MD5CryptoServiceProvider(); Byte[] buffer = Encoding.GetEncoding("utf-8").GetBytes(text.ToString()); Byte[] byteResult = MD5Pro.ComputeHash(buffer); string md5result = BitConverter.ToString(byteResult).Replace("-", ""); return md5result; } } }
