推荐答案

public static Boolean SendingMail(string From, string To, string Subject, string Body)
    {
        
            try
            {
                MailMessage m = new MailMessage("[email protected]", To);
                m.Subject = Subject;
                m.Body = Body;
                m.IsBodyHtml = true;
                m.From = new MailAddress(From);

                m.To.Add(new MailAddress(To));
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "mail.google.com";
              
                NetworkCredential authinfo = new NetworkCredential("[email protected]", "u1234");
                smtp.UseDefaultCredentials = false;
                smtp.Credentials = authinfo;
                smtp.Send(m);
                return true;

               


            }
            catch (Exception ex)
            {
                return false;
            }
        }

System.Net.Mail.MailMessage obj = new System.Net.Mail.MailMessage();

  SmtpClient serverobj = new SmtpClient();
            serverobj.Credentials = new NetworkCredential("YourEmailId", "YourPassword");
            serverobj.Port = 587;
            serverobj.Host = "smtp.gmail.com";
            serverobj.EnableSsl = false;
            obj = new System.Net.Mail.MailMessage();
            obj.From = new MailAddress("[email protected]", "AgileLearning.com", System.Text.Encoding.UTF8);
            obj.To.Add(ASPxtxtToUser.Text);
            obj.CC.Add(ASPxTexttoCc.Text);
            obj.Priority = System.Net.Mail.MailPriority.High;
            obj.Subject = txtSubject.Text;
            string date = DateTime.Now.ToString();
            obj.Body = ASPxMemo1.Text;
            serverobj.Send(obj);
            lblsend.Text = "Your Message Send Sucessfully";
