Using an email template in Kentico 11. Not able to run it's scheduled task when putting in multiple email address separated by semi-colons ";". example of code being used (credentials and stmpclient stuff blocked out)

                SmtpClient emailClient = new SmtpClient("--", --);

                    message.IsBodyHtml = true;
                    message.Subject = resolver.ResolveMacros(template.TemplateSubject);
                    message.Body = resolver.ResolveMacros(template.TemplateText);

Dmitry...your answer was correct! Thank you. Just had to do one tweak. It works now.

foreach (var individualEmail in template.TemplateCc.Split(';')) {

  message.CC.Add(new MailAddress(individualEmail.Trim()));

}

Hi Tom,

What particular error do you have when executing this code?

Dimitry, the error is very basic: "An invalid character was found in the mail header: ';'." No spaces between emails in the CC field, just the separating ';'.

What actual value can you see in template.TemplateCc? You probably should split it by ";" into actual email addresses and call message.CC.Add() in a cycle.

Apologize Dmitry -- Not sure I am clear on what you suggested. Do you mean either loop through the emails wanted in the CC field, or pass an array[] of emails separated by ';' ? Thanks.

Something like this:

foreach (var individualEmail in template.TemplateCc.Split(';'))
{
    message.CC.Add(individualEmail);
}

Dmitry....That makes sense. Let me try this today. I will get back and put in the post here if this works (which it looks like it would). :)

Dmitry...still the same error; Here is the code.
SmtpClient emailClient = new SmtpClient("-", -); { MailMessage message = new MailMessage(template.TemplateFrom, template.TemplateReplyTo); message.IsBodyHtml = true; message.Subject = resolver.ResolveMacros(template.TemplateSubject); message.Body = resolver.ResolveMacros(template.TemplateText);

                    foreach (var individualEmail in template.TemplateCc.Split(';'))
                    {
                        message.CC.Add(individualEmail);
                    }

                    foreach (var individualEmail in template.TemplateBcc.Split(';'))
                    {
                        message.Bcc.Add(individualEmail);
                    }


                    if (attachment != null)
                    {
                        message.Attachments.Add(attachment);
                    }
                    emailClient.Credentials = new NetworkCredential("-", "-");
                    emailClient.Send(message);
                }




                Then here is the error, "An invalid character was found in the mail header: ';'."
