winform利用smtp.163.com定制发送邮件

.cs 代码

   private void button3_Click(object sender, EventArgs e)
        {
            SendMail(sender,e);
        }

        private void button4_Click(object sender, EventArgs e)
        {
            System.Timers.Timer t = new System.Timers.Timer(10000);  //间隔时间10秒
            t.Elapsed += new ElapsedEventHandler(SendMail); //注册方法到事件
            t.AutoReset = false;   //是否反复执行
            t.Enabled = true;      //是否执行

        }

        private void SendMail(object sender,EventArgs e)  //目前发现163的smtp.163.com支持winform编程发送邮件
        {
            //Thread.Sleep(10000);
            //设置发送邮件内容
            MailMessage mm = new MailMessage();
            mm.From = new MailAddress("joe_9724@163.com", "发送邮箱");
            mm.Subject = "邮件标题";
            mm.Body = "邮件主体内容";
            mm.BodyEncoding = System.Text.Encoding.UTF8;
            mm.IsBodyHtml = true;
            mm.Priority = MailPriority.High;

            //添加收件箱
            mm.To.Add(new MailAddress("64060764@qq.com", "接收邮箱"));   //收件人
            mm.CC.Add(new MailAddress("joe9130@hotmail.com", "抄送邮箱"));  //需要抄送的人
            mm.Attachments.Add(new Attachment(@"C:\modifyddd.xml"));  //附件，这边的文件路径填写的是本程序执行的主机上的文件路径


            //设置发送选项
            SmtpClient client = new SmtpClient();
            client.Host = "smtp.163.com";
            client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential("joe_9724", "811123");
            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            //sendmail
            client.Send(mm);
 
        }
