using System.Web.Mail to send email

there are many demos for send a email with c sharp language .however,you will find that most of them will be failed because of SMTPServer.Especially,authorization is required.

 


public void SendEMail()




        ...{


            MailMessage mail = new MailMessage();


            mail.Priority = MailPriority.High;


            mail.From = "cccc@gmail.com";


            mail.To = "cccc@163.com";


            mail.Subject = "Send EMail System Demo";


            mail.Body = "Just for test.";


            mail.BodyEncoding = Encoding.UTF8;




            // authorization


            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", 1);


            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendemailaddress", mail.From);


            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpuserreplyemailaddress", mail.From);


            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpaccountname", "cccc@163.com");


            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "cccc");
