推荐答案

如果要使应用程序过期，应在CodeProject上查看此文章.

If you want to make your application to expire you should check this article on CodeProject.

Application Trial Maker[^]

您可以为此使用注册表.当应用程序首次安装或加载时，请检查您在应用程序中定义的计算机注册表中的特定注册表项.如果注册表项不存在，请将值设置为当前日期.每次加载应用程序时，请检查此注册表项的值.如果不到一年，请继续执行该应用程序，否则向用户显示该消息.

希望对您有所帮助！

You can use Registry for this purpose. When the application installs or loads for the first time check for a specific registry Key in computer''s registry that you define in your application. If the registry key does not exist, set the value to current date. Every time when your application loads, check for the value of this registry key. If it is less than one year, proceed with the application else display the message to user.

Hope it helps!
