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;}}
