看看这里讨论得正热呢!

client = new SmtpClient();
            client.Host = "smtp.邮箱服务器
            client.UseDefaultCredentials = false;
            client.Credentials = new ("你自己邮箱", "**********");
            client.DeliveryMethod =
             message = new MailMessage("你自己邮箱", "要发送的邮件地址");
            message.Subject = "图片";
            message.Body = "一张图片";
            message.BodyEncoding = System.Text.Encoding.UTF8;
            message.IsBodyHtml = true;
            message.Attachments.Add(new Attachment("e:\\a.jpg"));//附件
            try
            {
                client.Send(message);
                MessageBox.Show("Email发送成功");
            }
            catch (Exception ex)
            {
                MessageBox.Show("Email发送失败的原因 是" + ex.ToString());
            }
