我要写一个发送邮件的功能，但不知道发邮件的基本思路，知道的朋友贴一下，谢了！

  public static string SendEmail(string to, string subject, string confirmcode)
        {
            SmtpClient client = new SmtpClient("smtp.,25);
            //SmtpClient client = new SmtpClient("smtp., 465);
            //client.Host = "smtp.
            //client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential("kevintangsa@, "?");? 这个是你的密码
            //星号改成自己邮箱的密码
            //client.DeliveryMethod =
            client.EnableSsl = false;

            MailMessage message = new MailMessage("kevintangsa@,to);
            message.Subject = subject;
            message.Body = confirmcode;
            message.BodyEncoding = Encoding.UTF8;
            message.IsBodyHtml = false;


            //添加附件
            //Attachment data = new Attachment(@"附件地址如：e:\a.jpg", );
            //message.Attachments.Add(data);

            try
            {
                client.Send(message);
                return "成功";
            }
            catch (Exception ex)
            {
                return ex.Message;
            }

        }

补充！如果你是想实现注册邮件激活的功能，可以用jmail控件。自己去下！
