「.NET」几行代码实现自动发送邮件功能

public void SendEmailWithQQ(string toEmail, string subject, string body){ var fromAddress = new MailAddress("yourQQEmail@qq.com", "Your Name"); var toAddress = new MailAddress(toEmail); string fromPassword = "yourSMTPAuthorizationCode"; // 使用你从QQ邮箱获取的SMTP授权码
 var smtp = new SmtpClient { Host = "smtp.qq.com", Port = 587,  EnableSsl = true,  DeliveryMethod = SmtpDeliveryMethod.Network, UseDefaultCredentials = false, Credentials = new NetworkCredential(fromAddress.Address, fromPassword) };
 using (var message = new MailMessage(fromAddress, toAddress) { Subject = subject, Body = body }) { smtp.Send(message); }}
