推荐答案

制作试用版并不是一个容易的目标，它主要取决于它的安全性(如果您必须面对破解者)以及攻击者需要多少时间和资源.
您还可以实现一个自己动手的系统，即使用Symetric Encryption将密钥作为加密的XML文件存储在Isolated Storage中，在其中您可以数/保存天数(或开始数天).将其存储在永远不会进行搜索的位置，使用重复项，将xml保存为.dll(类似于Windows文件等)，这是一些小技巧，可以使普通的破解者更难.
您应该使用私钥/公钥过程为客户创建许可证.
那里有很多商业许可系统，但这也不是100％安全的事情，有些系统在一段时间后就被破解了，如果您为该系统投入了资金，那将是令人不安的.所有软件都是可破解的，尤其是由于CLI.
组合技术以防止破解是最好的方法，但是对于用户来说通常很烦，即是否需要永久的Internet连接才能启动程序.
因此，我的观点是您的案例Codeproject Aricles是正确的方法.


这是CP的示例:

Hi,

it''s not an easy goal to make a trial version, it mostly depends how secure it should be (if you have to face with crackers) and how much time and ressources the attacker comes with.
You could also realize a do-it-yourself system, i.e storing a key in the Isolated Storage as crypted XML file with Symetric Encryption where you count/save days (or starts). Storing it somewhere who never would search for, using duplicates, save xml as .dll which is named like windows files etc. are some little tricks to make it harder for common crackers.
You should use Private/Public Key procedure to create licenses to your customers.
There''re many commercial licencing systems out there, but that''s also not an 100% secure thing, some systems have been cracked after a while and it''s annonying if you have invested your funds for that system. All software is crackable, specially because of CLI.
Combining technologys to prevent cracking is the best way, but it''s often annoying for users i.e if permanent internet connection is required to start the program.
So my opinion is for your case Codeproject Aricles are the right way.


Here''s a example from CP:

Please don''t forget to obfuscate your Code.

是否尝试过CP搜索?检查此

您可以尝试http://installkey.codeplex.com

我用它来在我的应用程序中构建许可证系统.

you can try http://installkey.codeplex.com

I us it to build a licence system into my application.
