推荐答案

这是发送邮件的代码。

this is the code for sending mail.

MailMessage mail = new MailMessage();
              mail.To.Add(_objModelMail.To); //_objModelMail is the object of user defined model class
              mail.From = new MailAddress(_objModelMail.From);
              mail.Subject = _objModelMail.Subject;
              string Body = _objModelMail.Body;
              mail.Body = Body;
              mail.IsBodyHtml = true;
              SmtpClient smtp = new SmtpClient("smtp.gmail.com");

              smtp.Port = 587;
              smtp.UseDefaultCredentials = false;
              smtp.Credentials = new System.Net.NetworkCredential
              ("[e-mail]","pswd");// Enter seders User name and password
              smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
              smtp.EnableSsl = true;
                  smtp.Send(mail);

             }
