使用c#发送邮件

            using System.Net;

            using System.Net.Mail;

                      MailMessage messge = new MailMessage();//实例化邮件类

                         messge.From = new MailAddress("**@qq.com");//发件人账号

                          messge.To.Add("**@qq.com");//收件人账号

                          messge.Subject = "主题"//标题

                          messge.IsBodyHtml = true;//格式

                          messge.BodyEncoding = Encoding.UTF8;//编码

                         messge.Body = "正文"//正文

                          messge.Priority = MailPriority.Normal;//设置优先度

                          SmtpClient client = new SmtpClient("smtp.qq.com", 587);SMTP及端口

                          client.Credentials = new NetworkCredential("帐号", "密码");

                         client.EnableSsl = true;//安全连接

                         try {

                            client.Send(messge);//发送

                         Console.WriteLine("发送成功");

                         }

                         catch (Exception ex) {

                                                  Console.WriteLine(ex);

                                                  }

                         Console.Read();
