C#軟件注冊碼的實現(xiàn)代碼

更新時間：2013年05月20日 10:25:44 投稿：shangke

開發(fā)軟件時,當用到商業(yè)用途時,注冊碼與激活碼就顯得很重要了,現(xiàn)在的軟件技術實在在強了,各種國內外大型軟件都有注冊機制,但我們學習的是技術

第一步。根據(jù)卷標，CPU序列號，生成機器碼

// 取得設備硬盤的卷標號
        public static string GetDiskVolumeSerialNumber()
        {
            ManagementClass mc = new ManagementClass(“Win32_NetworkAdapterConfiguration”);
            ManagementObject disk = new ManagementObject(“win32_logicaldisk.deviceid=”d:”");
            disk.Get();
            return disk.GetPropertyValue(“VolumeSerialNumber”).ToString();
        }

        //獲得CPU的序列號
        public static 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;
        }
        //生成機器碼
        public static string getMNum()
        {
            string strNum = getCpu() + GetDiskVolumeSerialNumber();//獲得24位Cpu和硬盤序列號
            string strMNum = strNum.Substring(0, 24);//從生成的字符串中取出前24個字符做為機器碼
            return strMNum;
        }
        public static int[] intCode = new int[127];//存儲密鑰
        public static int[] intNumber = new int[25];//存機器碼的Ascii值
        public static char[] Charcode = new char[25];//存儲機器碼字
        public static void setIntCode()//給數(shù)組賦值小于10的數(shù)
        {
            for (int i = 1; i < intCode.Length; i++)
            {
                intCode[i] = i % 9;
            }
        }

第二步。根據(jù)機器碼生成注冊碼

復制代碼代碼如下:

//生成注冊碼

       public static string getRNum()
        {
            setIntCode();//初始化127位數(shù)組
            for (int i = 1; i < Charcode.Length; i++)//把機器碼存入數(shù)組中
            {
                Charcode[i] = Convert.ToChar(getMNum().Substring(i – 1, 1));
            }
            for (int j = 1; j < intNumber.Length; j++)//把字符的ASCII值存入一個整數(shù)組中。
            {
                intNumber[j] = intCode[Convert.ToInt32(Charcode[j])] + Convert.ToInt32(Charcode[j]);
            }
            string strAsciiName = “”;//用于存儲注冊碼
            for (int j = 1; j < intNumber.Length; j++)
            {
                if (intNumber[j] >= 48 && intNumber[j] <= 57)//判斷字符ASCII值是否0－9之間
                {
                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();
                }
                else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判斷字符ASCII值是否A－Z之間
                {
                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();
                }
                else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判斷字符ASCII值是否a－z之間
                {
                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();
                }
                else//判斷字符ASCII值不在以上范圍內
                {
                    if (intNumber[j] > 122)//判斷字符ASCII值是否大于z
                    {
                        strAsciiName += Convert.ToChar(intNumber[j] – 10).ToString();
                    }
                    else
                    {
                        strAsciiName += Convert.ToChar(intNumber[j] – 9).ToString();
                    }
                }
            }
            return strAsciiName;
        }

第三步。檢查注冊狀況，若沒有注冊，可自定義試用

復制代碼代碼如下:

/// <summary>
        /// 檢查注冊
        /// </summary>
        private void CheckRegist()
        {

this.btn_reg.Enabled = true;

                  RegistryKey retkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(“software”, true).CreateSubKey(“wxk”).CreateSubKey(“wxk.INI”);
                foreach (string strRNum in retkey.GetSubKeyNames())//判斷是否注冊
                {
                    if (strRNum == clsTools.getRNum())
                    {
                        thControl(true);
                        return;
                    }
                }
                thControl(false);
                Thread th2 = new Thread(new ThreadStart(thCheckRegist2));
                th2.Start();

          }
        }

        /// <summary>
        /// 驗證試用次數(shù)
        /// </summary>
        private static void thCheckRegist2()
        {
            MessageBox.Show(“您現(xiàn)在使用的是試用版，該軟件可以免費試用3000000次！”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);
            Int32 tLong;
            try
            {
                tLong = (Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0);
                MessageBox.Show(“感謝您已使用了” + tLong + “次”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            catch
            {
                Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0, RegistryValueKind.DWord);
                MessageBox.Show(“歡迎新用戶使用本軟件”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            tLong = (Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0);
            if (tLong < 3000000)
            {
                int Times = tLong + 1;
                Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, Times);
            }
            else
            {
                MessageBox.Show(“試用次數(shù)已到”, “警告”, MessageBoxButtons.OK, MessageBoxIcon.Warning);
                Application.Exit();
            }
        }
