Question

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email import encoders

fromaddr = "YOUR EMAIL"
toaddr = ["FISRT EMAIL ADDRESS YOU SEND TO", "SECOND EMAIL ADDRESS YOU SEND TO"]

msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "SUBJECT OF THE EMAIL"

body = "TEXT YOU WANT TO SEND"

msg.attach(MIMEText(body, 'plain'))

filename = "NAME OF THE FILE WITH ITS EXTENSION"
attachment = open("PATH OF THE FILE", "rb")

part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)

msg.attach(part)

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, "YOUR PASSWORD")

这是我得到一个错误的说法，无法编码列表元素 text = msg.as_string（） server.sendmail（fromaddr，toaddr，text） server.quit（）

如果要在电子邮件中添加多个收件人，则应从数据库中获取用户并添加到循环中。

导入System.Net;

导入System.Net.Mail;

根据您的情况获取用户数据。 enter code here var data = dataContext.website_request_logs.Where（＆＃34; condition＆＃34;）; //我们使用datacontext从website_request_logs表中获取数据。
foreach (website_request_log item in data) string EmailTo = item.email; string EmailFrom = item.fromEmail; string EmailSubject = item.emailSubject;
EmailUser(EmailTo ,EmailFrom ,EmailSubject );// call the function and send parameter in this.

4 .//我们可以使用电子邮件助手类发送电子邮件。

`private void EmailUser （字符串EmailTo，字符串EmailFrom，字符串EmailSubject ） {

         EmailHelper.SendEmail
                    (EmailFrom,
                    EmailTo,
                   EmailSubject,
                   );



    }`

SendEmail（）{MailMessage msg = new MailMessage（）; msg.From = new MailAddress（fromEmail，fromName）;

mail.Send（MSG）;

}

如何向此电子邮件代码添加多个收件人？
