C# 给自己写的软件，加注册码功能
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;
}
}

//生成注册码

C#软件加序列号激活、试用期限
程序员想尽各种办法给软件加密，用户就想尽各种办法对软件破解。
现在做软件试用限制，那么就讨论下软件的试用限制。总体来说，限制的方法有这么几种：
1.时间限制。
2.次数限制。
以时间限制为例，主要是用户从安装之日起， 限制用户使用天数。n天之后，就无法使用。这种限制主要是安装的时候，将当前日期写入注册表（或者硬盘上某文件）。当然，写入的是加密过的乱码字符。运行软件时，首先读取注册表（或者文件），如找不到
注册表（或者文件），则提示软件未注册。当正常读取后进行解密，得到注册日期，与当前日期进行比较，如果 当前日期 减去 注册日期 > n（允许试用天数），那么提示软件试用到期，直接退出软件。否则 提示可试用天数， 继续试用软件。 根据以上思路，那么
用户可以很容易破解软件。比如更改系统日期、或者删除注册表，重新安装软件等 。
针对用户的破解，对软件限制进行修改。如果试用软件必须联网，或者需要服务器端（比如聊天软件等客户端软件），当前时间要从去服务器的时间，防止用户更改客户机系统时间。或者服务器上对客户机进行记录，如记录主板id，安装时间，等等。。。
以上为客户机可联网的做法，当客户机无法上网，切不存在服务器，或者服务器就在本机时。以上做法将无法使用。
那么对於单机运行的软件，如果需要数据库，我们可以将注册时间等信息写入数据库。或者，我们可以采用一明一暗的做法，注册表是明，在硬盘的某角落，存放隐藏文件。软件需读取两处，对两处进行比较，一致则通过，不一致就退出程序。当然，安装的时候
对该文件不替换。 我想用户是不愿意为了使用你的软件而格式化整个硬盘的。
其实还有做法，就是每次运行软件，先将当前日期与注册表对比，看是否过期。如未过期，就对注册表进行一次更改，更改为当前日期，那么用户即使更改系统日期，他的试用期限也在逐渐缩小。为了防止用户重装，还是采用一明一暗的做法。
基本上就这些方法吧… 贴上测试代码：
