开发软件时，当⽤到商业⽤途时，注册码与激活码就显得很重要了。现在的软件破解技术实在太强了，各种国内外⼤型软件都有注册机制，但同时也不断地被破解。下⾯发的只是⼀个常⽤版本，发出源码被破就更容易了，但我们学习的是技术。当然也为以后⾃⼰的软件不会被轻易破解。 第⼀步。根据卷标，CPU序列号，⽣成机器码含盐废水处理
// 取得设备硬盘的卷标号
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();
}
//获得CPU的序列号
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;
方波信号发生器
}
return strCpu;
}
//⽣成机器码
public static 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 static int[] intCode =new int[127];//存储密钥
s100无人机
public static int[] intNumber =new int[25];//存机器码的Ascii值
public static char[] Charcode =new char[25];//存储机器码字
public static void setIntCode()//给数组赋值⼩于10的数
{
for(int i =1; i < intCode.Length; i++)
配送区域{
intCode[i]= i %9;
}
}
第⼆步。根据机器码⽣成注册码
public static 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(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++)ntest
{
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之间发光眼镜
{
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;
}
第三步。检查注册状况，若没有注册，可⾃定义试⽤
/// 检查注册
/// </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())//判断是否注册
{
if(strRNum == RNum())
{
thControl(true);
return;
}
}
thControl(false);
Thread th2 =new Thread(new ThreadStart(thCheckRegist2));
th2.Start();
}
/// <summary>
/// 验证试⽤次数
/// </summary>
private static void thCheckRegist2()
{
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); Int32 tLong;
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)
{
int Times = 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();
}
}
