Hi
I am working on a desktop application. I want to implement software activation in it so that we can provide trial version to client for 30 days, and after 30 days the software should ask for activation key.

I do not know how it should be implemented. Whether counting 30 days should start from installation date on client''s pc or some thing else.

您需要的是许可选项.

有多种方法可以实现这一目标
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.......

尝试:许可证密钥生成 [如何为我的C#应用​​创建产品密钥 [ ^ ]或:c#许可 [ ^ ]

还有，
.NET Framework的密码学101 [

What you need is a licensing option.

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: License Key Generation[^] or: How can I create a Product Key for my C# App[^] or: c# Licensing[^]

Also,
Cryptography 101 for the .NET Framework[^]

Hope this helps.
