[RESOLVED] .eml attachments

[Trice]

Greetings to all.

I'm writing a program that is supposed to create a .eml file containing either an xml or a pdf file or both as attachments.

Prior to writing this program, I had never seen what a .eml file looks like, let alone an .eml file with attachments(I never used any of the outlooks), so I got someone to send me an email containing both these attachments and save the .eml file, so I could use this as a template in my own program. So far so good.

However, I noticed that the pdf file, after having been attached, is a huge string of letters(see below). Probably some sort of encoding. My problem is, my program is going to be creating several different pdf files and adding them as attachments to .eml files. How do I encode the different pdf files into a similar huge string of text as the one below? Or am I going about this the wrong way? What would be an alternative way to do this? Because having to encode that long string of text seems like it would be a very daunting task.

Long story short: How do I programatically create an .eml file that contains a .pdf as attachment?

Any help whatsoever would be very appreciated. Thanks.

Below is a truncated(since the entire block of text is too long to post) version of what the section containing the pdf attachment looks like in the .eml file when opened by a text editor:

Hi all,

incase anybody out there is interested in this, I've been able to find a method in .net which, I think, should suffice for my program.

Base64 is what's used to code the pdf(and lots of other files attachments in general) into ASCII format for mail transfer and I found there is a method in .net called Convert.ToBase64String() that takes a string and converts it to base64. So I read the pdf to be used as an attachment into an array of bytes and passed this array of bytes as the argument of the Convert.ToBase64String() method. The method returns a string which I subsequently inserted at the appropriate position into my .eml template.

Hope this information helps anybody interested.
