通过SmtpClient，实现.NET框架下的SMTP邮件协议编程

SMTP - .NET发送邮件

1 example

using System.Net.Mail;

namespace SMTP
{ 
    /// <summary>
    /// A utility provides SMTP mail functions
    /// </summary>
    public static class SMTPUtility
    {
        /// <summary>
        /// send an email in the name of 'System Notification'(demo.noreply@cn.demo.com) via SMTP
        /// </summary>
        /// <param name="mailto"></param>
        /// <param name="mailBody"></param>
        /// <param name="mailSubject"></param>
        public static void SendMail(string mailto, string mailBody, string mailSubject)
        {
            MailMessage MyMail = new MailMessage();
            MyMail.From = new MailAddress("demo.noreply@cn.demo.com", "System Notification");
            MyMail.To.Add(mailto);
            MyMail.Subject = mailSubject;
            MyMail.IsBodyHtml = true;
            MyMail.Body = mailBody;

            SmtpClient smtp = new SmtpClient();
            smtp.Host = "hostname or IP address";
            smtp.Send(MyMail);
        }
    }
}

• 注：MailMessage和SmtpClient通过using System.Net.Mail;导入namespace。
