注册表入门次数基础软件(注册码机器码软件字符次数)「注册表编码」

综合练习-限制软件的使用次数为了使软件能够更好的推广,开发商希望能有更多的用户使用软件,但他们又不想让用户长时间的免费使用未经授权的软件,这个时候就可以推出试用版软件,限制用户的使用次数,若用户感觉使用方便的时候,可以花钱获取正版授权的注册码
本节将实现限制软件使用次数的功能,运行后,如果未注册,则提示用户使用过几次,然后进入窗体主程序,单击窗体中的注册按钮,自动获取注册码,用户输入注册码后单击“注册”,可成功注册程序,注册后将不再提示软件试用次数
完整示例代码:using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Management;namespace ClassLibrary1{ public class SoftReg { // 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=\"d:\""); disk.Get(); return disk.GetPropertyValue("VolumeSerialNumber").ToString(); } //获得CPU的序列号 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; } //生成机器码 public string getMNum() { string strNum = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号 string strMNum = strNum.Substring(0, 24);//从生成的字符串中取出前24个字符做为机器码 return strMNum; } public int[] intCode = new int[127];//存储密钥 public int[] intNumber = new int[25];//存机器码的Ascii值 public char[] Charcode = new char[25];//存储机器码字 public void setIntCode()//给数组赋值小于10的数 { for (int i = 1; i < intCode.Length; i++) { intCode[i] = i % 9; } } //生成注册码 public string getRNum() { 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(this.getMNum().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 = "";//用于存储注册码 for (int j = 1; j < intNumber.Length; j++) { if (intNumber[j] >= 48 && intNumber[j] <= 57)//判断字符ASCII值是否0-9之间 { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判断字符ASCII值是否A-Z之间 { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判断字符ASCII值是否a-z之间 { 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(); } } } return strAsciiName; } }}
