1.首先引入命名空间using system.net.mail;
2.将发送的邮件的功能封装成一个类,该类中包含了发送邮件的基本功能:收件人(多人),抄送(多人),发送人,主题,邮件正文,附件等,封装的email类如下:

复制代码 代码如下:

public class email
    {
        /// <summary>
        /// 发送者
        /// </summary>
        public string mailfrom { get; set; }

        /// <summary>
        /// 收件人
        /// </summary>
        public string[] mailtoarray { get; set; }

        /// <summary>
        /// 抄送
        /// </summary>
        public string[] mailccarray { get; set; }

        /// <summary>
        /// 标题
        /// </summary>
        public string mailsubject { get; set; }

        /// <summary>
        /// 正文
        /// </summary>
        public string mailbody { get; set; }

        /// <summary>
        /// 发件人密码
        /// </summary>
        public string mailpwd { get; set; }

        /// <summary>
        /// smtp邮件服务器
        /// </summary>
        public string host { get; set; }

        /// <summary>
        /// 正文是否是html格式
        /// </summary>
        public bool isbodyhtml { get; set; }

        /// <summary>
        /// 附件
        /// </summary>
        public string[] attachmentspath { get; set; }

        public bool send()
        {
            //使用指定的邮件地址初始化mailaddress实例
            mailaddress maddr = new mailaddress(mailfrom);
            //初始化mailmessage实例
            mailmessage mymail = new mailmessage();


            //向收件人地址集合添加邮件地址
            if (mailtoarray != null)
            {
                for (int i = 0; i < mailtoarray.length; i++)
                {
                    mymail.to.add(mailtoarray[i].tostring());
                }
            }

            //向抄送收件人地址集合添加邮件地址
            if (mailccarray != null)
            {
                for (int i = 0; i < mailccarray.length; i++)
                {
                    mymail.cc.add(mailccarray[i].tostring());
                }
            }
            //发件人地址
            mymail.from = maddr;

            //电子邮件的标题
            mymail.subject = mailsubject;

            //电子邮件的主题内容使用的编码
            mymail.subjectencoding = encoding.utf8;

            //电子邮件正文
            mymail.body = mailbody;

            //电子邮件正文的编码
            mymail.bodyencoding = encoding.default;

            mymail.priority = mailpriority.high;

            mymail.isbodyhtml = isbodyhtml;

            //在有附件的情况下添加附件
            try
            {
                if (attachmentspath != null && attachmentspath.length > 0)
                {
                    attachment attachfile = null;
                    foreach (string path in attachmentspath)
                    {
                        attachfile = new attachment(path);
                        mymail.attachments.add(attachfile);
                    }
                }
            }
            catch (exception err)
            {
                throw new exception("在添加附件时有错误:" + err);
            }

            smtpclient smtp = new smtpclient();
            //指定发件人的邮件地址和密码以验证发件人身份
            smtp.credentials = new system.net.networkcredential(mailfrom, mailpwd);


            //设置smtp邮件服务器
            smtp.host = host;

            try
            {
                //将邮件发送到smtp邮件服务器
                smtp.send(mymail);
                return true;

            }
            catch (system.net.mail.smtpexception ex)
            {
                return false;
            }

        }
    }

3.页面调用发送邮件的类

复制代码 代码如下:

protected void send_click(object sender, eventargs e)
        {
            email email = new email();
            email.mailfrom = "发送人的邮箱地址";
            email.mailpwd = "发送人邮箱的密码";
            email.mailsubject = "邮件主题";
            email.mailbody = "邮件内容";
            email.isbodyhtml = true;    //是否是html
            email.host = "smtp.126.com";//如果是qq邮箱则:smtp:qq.com,依次类推
            email.mailtoarray = new string[] { "******@qq.com","12345678@qq.com"};//接收者邮件集合
            email.mailccarray = new string[] { "******@qq.com" };//抄送者邮件集合
            if (email.send())
            {
                response.write("<script type='text/javascript'>alert('发送成功!');history.go(-1)</script>");//发送成功则提示返回当前页面;

            }
            else
            {
                response.write("<script type='text/javascript'>alert('发送失败!');history.go(-1)</script>");
            }
        }
