Hi,

I am using Crystal Reports for Visual Studio 2010. Using Crystal Reports , I plan to export a file in PDF format. But I want to protect some of these PDF files using a Password. Would it be possible to do so using some C# library. I do not intend to use any third party library like Itext or any thing else? Any sample code would be helpful.

Thanks for your help.

推荐答案

不想使用第三方库?祝你好运！

大约需要6个月的时间来编写自己的库才能做到这一点，或者您可以只获取iTextSharp或其他库，并在大约30分钟内编写密码解决方案.

想要做什么?

Don''t want to use a third party library?? Good luck with that!

It would take you approximately 6 months to code up your own library to do it, or you could just get iTextSharp, or some other library, and code up your password solution in about 30 minutes.

Which would like to do?
