推荐答案

我认为根据你的问题，这个技巧可能会奏效。假设您在桌面上安装软件时创建文本文件，此文件可以保存安装日期，就像今天日期一样。当您的软件在系统上运行时检查页面加载事件上的日期。如果日期超过，则消息显示您的试用期限已过期。

I think may be this trick is worked, as per your problem. Suppose when you install the software in desktop, Create a Textfile, this file can hold of the Installation Date like that Today Date. When your software is Run on System check Date on Page Loading Event. If Date is exceed then message show your trial Period is Expired.

当您第一次运行您的应用程序时，在注册表中显示一个显示安装日期的条目，然后下次比较此条目使用当前日期，如果日差小于365，则运行您的应用程序，您可以在program.cs文件中执行此操作
