推荐答案

IMO的最佳方法是使用条件编译来创建不包含您不想放弃的代码的试验.否则，有人会逆向工程并打败您的审判.

The best way IMO is to use conditional compilation to create a trial that doesn''t include the code you don''t want to give away. Otherwise someone will reverse engineer and defeat your trial.

为什么如果不注册，为什么不只包括一个nag屏幕呢?每5分钟或每当使用主要功能时，就会显示nag屏幕.

不要忘记使用商业混淆工具来混淆您的代码.不要使用VS2008附带的版本，因为它很容易进行逆向工程.

Why don''t you just include a nag screen if it''s not registered. Have the nag screen come up every 5 minutes or whenever a major feature is used.

Don''t forget to obfuscate your code with a COMMERCIAL obfuscation tool. Don''t use the one that comes with VS2008 because it can easily be reverse engineered.
