来源：互联网发布：西部数码域名证书查询编辑：程序博客网时间：2024/09/21 08:50

需要用到：

1.System.Net.Mail;

2.QQ邮箱的POP3/SMTP服务码

QQ邮箱的POP3/SMTP服务码获取方法：

1.打开qq邮箱：

2.进入设置页面--》账户：（往下翻）开启服务POP3/SMTP服务，QQ邮箱会给一个POP3/SMTP服务码保存下来

代码:

 /// <summary>        /// 发送邮件,成功返回true,否则false        /// </summary>        /// <param name="to">收件人</param>        /// <param name="body">内容</param>        /// <param name="title">标题</param>        /// <param name="whichEmail">是否join</param>        /// <param name="path">附件</param>        /// <param name="Fname">姓名</param>        /// <returns>结果</returns>        public static bool SentMailHXD(string to, string body, string title, string whichEmail, string path, string Fname)        {            bool retrunBool = false;            MailMessage mail = new MailMessage();            SmtpClient smtp = new SmtpClient();            string strFromEmail = "";//你的邮箱            string strEmailPassword = "";//QQPOP3/SMTP服务码            try            {                mail.From = new MailAddress("" + Fname + "<" + strFromEmail + ">");                mail.To.Add(new MailAddress(to));                mail.BodyEncoding = Encoding.UTF8;                mail.IsBodyHtml = true;                mail.SubjectEncoding = Encoding.UTF8;                mail.Priority = MailPriority.Normal;                mail.Body = body;                mail.Subject = title;                smtp.Host = "smtp.qq.com";                smtp.DeliveryMethod = SmtpDeliveryMethod.Network;                smtp.Credentials = new System.Net.NetworkCredential(strFromEmail, strEmailPassword);                //发送邮件                smtp.Send(mail);   //同步发送                retrunBool = true;            }            catch (Exception ex)            {                retrunBool = false;            }            // smtp.SendAsync(mail, mail.To); //异步发送 （异步发送时页面上要加上Async="true" ）            return retrunBool;        }

调用方法即可：

   SentMailHXD("收件人", "内容, "标题", "抄送", "附件（附件方法我移除了）", "你的姓名");</span>
