I am using Rotativa to convert my view to pdf. I would like to send that generated pdf as an email attachment (without having to download it first to disk).

I've been following a bunch of tutorials to do this but I just keep going round in circles. I would much appreciate any help I can get.

What I have tried:

C#

public async Task<iactionresult>SomeReport()
    {
    ...
    return new ViewAsPdf (report)
    }
    return view();


    MemoryStream memoryStream = new MemoryStream();

    MimeMessage msg = new MimeMessage();
    MailboxAddress from = new MailboxAddress ("Name", "emailAddress")
    msg.From.Add(from);
    MailboxAddress to = new MailboxAddress ("Name", "emailAddress")
    msg.From.Add(to);
    BodyBuilder bd = new BodyBuilder();
    bb.HtmlBody ="some text";
    bb.Attachments.Add("attachmentName", new MemoryStream());
    msg.Body = bb.ToMessageBody();
    SmtpClient smtp = new SmtpClient();
    smtp.Connect("smtp.gmail.com",465, true);
    smtp.Authenticate("emailAddress", "Pwd");
    smtp.Send(msg);
    smtp.Disconnect(true);
    smtp.Dispose();

Referring to following documents about your use case on how to get the PDF:
Creating PDF In ASP.NET Core MVC Using Rotativa.AspNetCore[^]
How to create PDF from Asp.net MVC with RotativaHQ[^]

Once that is in place, code snippet like below should do the job:

C#

var attachment = new Attachment(new MemoryStream(pdfBytes), PdfFileName); //this is from the articles referred above

MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("to@to.t"));
mailMessage.From = new MailAddress("from@from.f");
mailMessage.Subject = "my pdf attached";
mailMessage.Attachments.Add(attachment);

SmtpClient smtp = new SmtpClient();
smtp.Connect("smtp.gmail.com",465, true);
smtp.Authenticate("emailAddress", "Pwd");
smtp.Send(mailMessage);

PS: Make sure to take care of memory release for the objects.
