本文介绍的实现c#软件注册码的方法,共分为三个步骤。
步骤1,根据卷标,CPU序列号,生成机器码。
// 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;
}
}
步骤2,根据机器码 生成注册码。
步骤3,检查注册状况,若没有注册,可自定义试用。
/// <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();
}
}
