I am trying to send email with attached pdf, my pdf is in byte array. and when i try to send mail (without pdf) it shows

Message = The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at

my code is `string senderEmail = System.Configuration.ConfigurationManager.AppSettings["SenderEmail"].ToString();
string senderPassword = System.Configuration.ConfigurationManager.AppSettings["SenderPassword"].ToString();

            SmtpClient client = new SmtpClient("smtp.gmail.com", 587);

            client.EnableSsl = true;

            client.Timeout = 100000;

            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            client.UseDefaultCredentials = false;

            client.Credentials = new NetworkCredential(senderEmail, senderPassword);



            MailMessage mailMassege = new MailMessage(senderEmail, toEmail, subject, body);

            mailMassege.IsBodyHtml = true;

            mailMassege.BodyEncoding = Encoding.UTF8;





            client.Send(mailMassege);`

and my pdf is in byte array
byte applicationPDFData = actionResult.BuildPdf(ControllerContext);
System.IO.File.WriteAllBytes(filePath + "/hello.pdf", applicationPDFData);

I want to to send mail with this pdf.
thanks in advance

You have to create an attachment and append it to the mail Attachemnts list.
here is an example:

byte applicationPDFData = actionResult.BuildPdf(ControllerContext);

Attachment attPDF = new Attachment(new MemoryStream(applicationPDFData), name);



EmailMessage emailMessage = new EmailMessage();

emailMessage.To.Add( new EmailRecipient( toEmail ) );

emailMessage.Subject = subject;

emailMessage.Body = body;

emailMessage.Attachments.Add( attPDF );
