Web服务器请求在电子邮件附件C＃中生成pdf [英] Webserver request to generate pdf in an email attachment C#

问题描述

如果您能告诉我我的代码需要做什么，我会很感激。我的代码动态地使用iTextSharp从HTML创建PDF并将生成的PDF作为电子邮件附件发送。但我需要做的就是如何向
返回Base64编码PDF的Web服务器发送请求？因为我需要执行相同的过程，发送请求以将Base64编码的PDF附加到电子邮件中！任何帮助将不胜感激。

I'd appreciate if you could tell me what do I need to do with my code. My code below works dynamically in creating PDF from HTML using iTextSharp and send the generated PDF as Email Attachment. But all I need to do is how to send a request to a web server that returns a Base64 Coded PDF? As I need to do the same procedure sending a request to get Base64 coded PDF to be attached to emails! Any help would be appreciated.

然后对其进行编码。 ASP.NET论坛的人员可以相应地指导您。

Please post questions related to ASP.NET and web applications in the ASP.NET forums (http://forums.asp.net ). Returning an encoded file only makes sense in current cases for certain types of apps. For other web apps you'd just return the regular file and then encode it. The ASP.NET forums folks will be able to direct you accordingly.
