推荐答案

您可以在应用程序中具有某种许可功能.

有多种方法可以实现这一目标
1)加密的许可证文件，其中包含到期日期等.
2)注册表中保存的加密许可证密钥
3)需要Internet连接的质询/响应机制
4)可能是其他人.......
尝试:许可证密钥生成 [如何为我的C#应用​​创建产品密钥 [ ^ ]或:c#许可 [ ^ ]

还有，
.NET Framework的密码学101 [

You can have sort of licensing feature in your application.

There are different ways to achieve this
1) encrypted license files that contains the expiry dates etc.
2) encrypted license keys held in the registry
3) challenge/response mechanism which require an internet connection
4) probably others.......
Try: License Key Generation[^] or: How can I create a Product Key for my C# App[^] or: c# Licensing[^]

如果我告诉过您，是否只有一种方法，每个人都使用过，那么您肯定知道每个人都会知道如何打败该系统?您需要考虑一种方法.我倾向于将应用程序首次运行的日期以及上次运行的系统日期存储在我试图隐藏在系统中的文件中，Vista使此操作变得更加困难.然后，您可以判断是否有人为了节省更多时间而浪费时间，以及他们的审判是否结束.

If I told you, if there was one single way, that everyone used, then surely you realise that everyone would know how to defeat the system ? You need to think of a way. I tend to store the date the app was first run, and the system date when it was last run, in a file that I try to hide in the system, Vista makes this harder to do. Then you can tell if someone wound back the clock to get more time, as well as if their trial is over.

您回来了.使用谷歌找到一个图书馆，做你想要的.实际上有数十种方法可以做到这一点，对于我们在这里列出的列表肯定太多了.

就像我昨天说的那样，这是浪费时间.用软件可以做的任何事情，都可以用软件撤消.

You''re back. Use google to find a library that does what you want. there are literally dozens of ways to do this, certainly too many for us to list here.

Like I said yesterday, it''s a waste of time. Anything that can be done with software, can be UNDONE with software.
