Answer 2

System.Net.Mail.MailMessage mail = new MailMessage();
            mail.From = new MailAddress("####@####");//发件人的邮箱
            mail.To.Add("Jimmy") ;//收件人的邮箱
            mail.Subject = "111";//邮件主题
            mail.Body = "22222";//邮件正文
            mail.IsBodyHtml = true;
            System.Net.Mail.Attachment mailAttachment = new Attachment(@"D:\新建 文本文档.txt");//邮件附件
            mail.Attachments.Add(mailAttachment);
            SmtpClient c = new SmtpClient();
            //验证 
            c.Host = "192.168.0.25";
            c.UseDefaultCredentials = false;
            c.Credentials = new System.Net.NetworkCredential("Jack","123 ");
            c.DeliveryMethod = SmtpDeliveryMethod.Network;
            c.Send(mail);我原来写的,改了一下,你试试.根据你的要求再修改一下
