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
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;
}
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
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++)
{
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
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++)
{
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;
}
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>
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 == clsTools.getRNum())
{
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_MACHINESOFTWAREangel”, “UseTimes”, 0);
MessageBox.Show(“感谢您已使用了” + tLong + “次”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch
{
Registry.SetValue(“HKEY_LOCAL_MACHINESOFTWAREangel”, “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_MACHINESOFTWAREangel”, “UseTimes”, 0);
if (tLong < 3000000)
{
int Times = tLong + 1;
Registry.SetValue(“HKEY_LOCAL_MACHINESOFTWAREangel”, “UseTimes”, Times);
}
else
{
MessageBox.Show(“试用次数已到”, “警告”, MessageBoxButtons.OK, MessageBoxIcon.Warning);
Application.Exit();
}
}
