這篇文章主要介紹了C#實(shí)現(xiàn)按數(shù)據(jù)庫郵件列表發(fā)送郵件的方法,涉及C#讀取數(shù)據(jù)庫及通過自定義函數(shù)發(fā)送郵件的相關(guān)技巧,具有一定參考借鑒價(jià)值,需要的朋友可以參考下
本文實(shí)例講述了C#實(shí)現(xiàn)按數(shù)據(jù)庫郵件列表發(fā)送郵件的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下:
- using System;
- using System.Net;
- using System.Net.Mail;
- using System.Text;
- using System.Threading;
- delegate void sendDelegate(string from, string to, string subject, string body, string host, int port, string userName, string password);
- /// <summary>
- /// 發(fā)送電子郵件
- /// </summary>
- /// <param name="from">發(fā)件人</param>
- /// <param name="to">收件人</param>
- /// <param name="subject">郵件主題</param>
- /// <param name="body">郵件內(nèi)容</param>
- /// <param name="host">發(fā)送服務(wù)地址(smtp.qq.com)</param>
- /// <param name="port">發(fā)送郵件服務(wù)器端口(25) int型</param>
- /// <param name="userName">用戶名</param>
- /// <param name="password">密碼</param>
- public void sendmail(string from, string to, string subject, string body, string host, int port, string userName, string password)
- {
- MailMessage message = new MailMessage(from, to, subject, body);
- message.IsBodyHtml = true;
- message.BodyEncoding = Text.Encoding.UTF8;
- message.Attachments.Add(new Attachment("c://log.log"));
- SmtpClient client = new SmtpClient(host, port);
- client.Credentials = new NetworkCredential(userName, password);
- client.DeliveryMethod = SmtpDeliveryMethod.Network;
- client.Send(message);
- }
- SqlConnection conn = new SqlConnection();
- conn.ConnectionString = "Data Source=(local);Integrated Security=SSPI;Initial Catalog=db_showHouse"; //打開連接
- conn.Open();
- SqlCommandcmd = new SqlCommand("select Email from Employee", conn);
- SqlDataReader drNew = cmd.ExecuteReader();
- if (drNew.HasRows)
- {
- while (drNew.Read())
- new sendDelegate(sendmail).BeginInvoke("[email protected]",drNew[0].ToString(),"subject","body","smtp.somescompany.com",25,"userName","password");
- }
- drNew.Close();
希望本文所述對大家的C#程序設(shè)計(jì)有所幫助。
