利用System.Net.Mail 实现电子邮件发送到简单邮件传输协议 (SMTP) 服务器进行传送.

1.修改webconfig文件

<system.net>
      <mailSettings>
        <smtp>
          <network host="smtp host" port="25" userName="username" password="password"/>
        </smtp>
      </mailSettings>

</system.net>

2. 点击button实现邮件发送

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    public void SendEmail(string from, string to, string bcc, string cc, string subject, string body, string mAttachment)
    {
        MailMessage NewEmail = new MailMessage();
        // 表示电子邮件发件人或收件人的地址
        //MailAddress from = new MailAddress("ben@contoso.com", "Ben Miller");
        NewEmail.From = new MailAddress(from,from);
    
        NewEmail.To.Add(new MailAddress(to));
        // 你也可以添加一个地址到集合 NewEmail.To = new MailAddressCollection().Add(new MailAddress(to)); 
        NewEmail.Bcc.Add(new MailAddress(bcc));
        if (!String.IsNullOrEmpty(cc))
        {
            NewEmail.CC.Add(new MailAddress(cc));
        }
        NewEmail.Subject = subject;
        NewEmail.Body = body;
        Attachment MsgAttach = new Attachment((mAttachment));
        NewEmail.Attachments.Add(MsgAttach);
        NewEmail.IsBodyHtml = true;
        NewEmail.Priority = MailPriority.Normal;
        SmtpClient mSmtpClient = new SmtpClient();
        mSmtpClient.Send(NewEmail);
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string from = "发件人";
        string to = "收件人";
        string bcc = "密件抄送 (BCC)";
        string cc = "抄送 (CC)";
        string subject = "主题";
        string body = "邮件正文";
        string mAttachment = "附件";
        SendEmail(from, to, bcc, cc, subject, body, mAttachment);
    }
}
