我正在尝试从我的 C# 代码发送电子邮件。这是一个示例
MailMessage message = new MailMessage();
message.To.Add("milos90zr@gmail.com");
message.Subject = "Registration";
message.From = new System.Net.Mail.MailAddress("milos90zr@hotmail.com");
message.Body = "OK";
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Send(message);
但是我的代码中断了,这是错误:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. hn4sm3874638bkc.2 - gsmtp
