推荐答案

就像dll到期一样. DLL只是程序集，不具有到期"功能.

听起来您需要许可.如果是这样，有多种方法可以实现:
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.......

试试:

c#许可 [ ^ ]


另外，请看这些:

There is nothing like expiration of a dll. DLL is just an assembly and does not have capability of ''expiring''.

Sounds like you are in need of licensing. If so, 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:
