我尝试过：
使用SMTPUser =example.gmail.com，SMTPPassword =password;
//现在实例化MailMessage的新实例
MailMessage mail = new MailMessage（）;
//设置邮件的发件人地址
mail.From =新邮件地址（SMTPUser，AspnetO）;
//设置邮件的收件人地址
mail.To.Add（ToEmail）;
//设置邮件主题
mail.Subject = Subject ;
//设置邮件正文
mail.Body = Body;
//即使您没有发送HTML消息也要保持原样
mail.IsBodyHtml = true;
//将邮件的优先级设置为正常
mail.Priority = MailPriority.Normal;
//实例化a SmtpClient的新实例
SmtpClient smtp = new SmtpClient（）;
smtp.Port = 587; //或者您也可以使用端口＃587
/
//如果您使用SSL / TLS使用安全认证，那么true否则为false
smtp.EnableSsl = true;
smtp.Send（mail）;
Thank you,

What I have tried:
tring SMTPUser = "example.gmail.com", SMTPPassword = "password";
//Now instantiate a new instance of MailMessage
MailMessage mail = new MailMessage();
//set the sender address of the mail message
mail.From = new MailAddress(SMTPUser, "AspnetO");
//set the recepient addresses of the mail message
mail.To.Add(ToEmail);
//set the subject of the mail message
mail.Subject = Subject;
//set the body of the mail message
mail.Body = Body;
//leave as it is even if you are not sending HTML message
mail.IsBodyHtml = true;
//set the priority of the mail message to normal
mail.Priority = MailPriority.Normal;
//instantiate a new instance of SmtpClient
SmtpClient smtp = new SmtpClient();
smtp.Port = 587; //or you can also use port# 587
/
//if you are using secure authentication using SSL/TLS then "true" else "false"
smtp.EnableSsl = true;
smtp.Send(mail);
