Infopath form attachment Analysis

Recently, due to development requirements, we need to separate the two attachments in the infopath form and save them to another document library.

I found less information on the Internet. I have integrated some English documents and learned a little bit about it. I am afraid to share it exclusively.

Main points:

1. code encoding and decoding

2. The entire attachment is stored in a document library as a project.

Code encoding and decoding: the main reference: http://support.microsoft.com/kb/892730/zh-cn? Spid = 11303 & SID = 216, mainly two infopathattachmentencoder. CS and infopathattachmentdecoder. CS ..

The entire attachment is stored as a project in a document library: The saveattachment method is mainly modified.

 

Because I am usingInfopath form post encoding. C # language is used..
