I'm working with C# on Windows servers for a web application stored on the IIS Server.
I would like to create an eml file from :
- an html content (string)
- some attachments that are loaded in memory
- a string subject
- string recipients
- string sender
The main problem is that I am not allowed to store files on the host server (not even in a temporary directory or if I delete them after).
I saw many threads explaining how to create an eml file with the help of SmtpClient. But we always need to use a directory to save the file.
Do someone knows a way to do that ? Or to create a directory in memory (which seems undoable) ?
Thanks for everyone who will read me
[EDIT] Using jstedfast's answer below and the Mime documentation, I could figure a way. Here is a POC in case someone needs it later.
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Joey", "joey@friends.com"));
message.To.Add(new MailboxAddress("Alice", "alice@wonderland.com"));
message.Subject = "How you doin?";
var builder = new BodyBuilder();
// Set the plain-text version of the message text
builder.TextBody = @"Hey Alice,
What are you up to this weekend? Monica is throwing one of her parties on
Saturday and I was hoping you could make it.
Will you be my +1?
-- Joey
";
// We may also want to attach a calendar event for Monica's party...
builder.Attachments.Add("test.pdf", attachmentByteArray);
// Now we just need to set the message body and we're done
message.Body = builder.ToMessageBody();
using (var memory = new MemoryStream())
{
message.WriteTo(memory);
}
