c#软件代码 实现 注册码

第一步。根据卷标，CPU序列号，生成机器码

复制代码代码如下:

//取得设备硬盘的卷标号
       publicstaticstringGetDiskVolumeSerialNumber()
       {
           ManagementClassmc=newManagementClass(“Win32_NetworkAdapterConfiguration”);
           ManagementObjectdisk=newManagementObject(“win32_logicaldisk.deviceid=”d:”");
           disk.Get();
           returndisk.GetPropertyValue(“VolumeSerialNumber”).ToString();
       }

       //获得CPU的序列号
       publicstaticstringgetCpu()
       {
           stringstrCpu=null;
           ManagementClassmyCpu=newManagementClass(“win32_Processor”);
           ManagementObjectCollectionmyCpuConnection=myCpu.GetInstances();
           foreach(ManagementObjectmyObjectinmyCpuConnection)
           {
               strCpu=myObject.Properties["Processorid"].Value.ToString();
               break;
           }
           returnstrCpu;
       }
       //生成机器码
       publicstaticstringgetMNum()
       {
           stringstrNum=getCpu()+GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号
           stringstrMNum=strNum.Substring(0,24);//从生成的字符串中取出前24个字符做为机器码
           returnstrMNum;
       }
       publicstaticint[]intCode=newint[127];//存储密钥
       publicstaticint[]intNumber=newint[25];//存机器码的Ascii值
       publicstaticchar[]Charcode=newchar[25];//存储机器码字
       publicstaticvoidsetIntCode()//给数组赋值小于10的数
       {
           for(inti=1;i<intCode.Length;i++)
           {
               intCode[i]=i%9;
           }
       }


第二步。根据机器码生成注册码
复制代码代码如下:

       //生成注册码    

      publicstaticstringgetRNum()
       {
           setIntCode();//初始化127位数组
           for(inti=1;i<Charcode.Length;i++)//把机器码存入数组中
           {
               Charcode[i]=Convert.ToChar(getMNum().Substring(i?1,1));
           }
           for(intj=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]);
           }
           stringstrAsciiName=“”;//用于存储注册码
           for(intj=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();
               }
               elseif(intNumber[j]>=65&&intNumber[j]<=90)//判断字符ASCII值是否A－Z之间
               {
                   strAsciiName+=Convert.ToChar(intNumber[j]).ToString();
               }
               elseif(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();
                   }
               }
           }
           returnstrAsciiName;
       }


第三步。检查注册状况，若没有注册，可自定义试用     
复制代码代码如下:
///<summary>
       ///检查注册
       ///</summary>
       privatevoidCheckRegist()
       {

               this.btn_reg.Enabled=true;

                 RegistryKeyretkey=Microsoft.Win32.Registry.CurrentUser.OpenSubKey(“software”,true).CreateSubKey(“wxk”).CreateSubKey(“wxk.INI”);
               foreach(stringstrRNuminretkey.GetSubKeyNames())//判断是否注册
               {
                   if(strRNum==clsTools.getRNum())
                   {
                       thControl(true);
                       return;
                   }
               }
               thControl(false);
               Threadth2=newThread(newThreadStart(thCheckRegist2));
               th2.Start();

         }
       }

       ///<summary>
       ///验证试用次数
       ///</summary>
       privatestaticvoidthCheckRegist2()
       {
           MessageBox.Show(“您现在使用的是试用版，该软件可以免费试用3000000次！”,“提示”,MessageBoxButtons.OK,MessageBoxIcon.Information);
           Int32tLong;
           try
           {
               tLong=(Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”,“UseTimes”,0);
               MessageBox.Show(“感谢您已使用了”+tLong+“次”,“提示”,MessageBoxButtons.OK,MessageBoxIcon.Information);
           }
           catch
           {
               Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”,“UseTimes”,0,RegistryValueKind.DWord);
               MessageBox.Show(“欢迎新用户使用本软件”,“提示”,MessageBoxButtons.OK,MessageBoxIcon.Information);
           }
           tLong=(Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”,“UseTimes”,0);
           if(tLong<3000000)
           {
               intTimes=tLong+1;
               Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”,“UseTimes”,Times);
           }
           else
           {
               MessageBox.Show(“试用次数已到”,“警告”,MessageBoxButtons.OK,MessageBoxIcon.Warning);
               Application.Exit();
           }
       }
