两种.NET定时发送邮件代码实例(2)-木庄网络博客

sendMail方法

public static string sendMail(string mailSubjct, string mailBody, string mailFrom, List<string> mailAddress, string hostIP, string username, string password, bool ssl)
  {
   string str = "";
   try
   {
    MailMessage message = new MailMessage
    {
     IsBodyHtml = true,
     Subject = mailSubjct,
     Body = mailBody,
 
     From = new MailAddress(mailFrom)
    };
    for (int i = ; i < mailAddress.Count; i++)
    {
     message.To.Add(mailAddress[i]);
    }
    SmtpClient client = new SmtpClient
    {
     EnableSsl = ssl,
     UseDefaultCredentials = false
    };
    NetworkCredential credential = new NetworkCredential(username, password);
    client.Credentials = credential;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.Host = hostIP;
    client.Port = x;
    client.Send(message);
   }
   catch (Exception exception)
   {
    str = exception.Message;
   }
   return str;
  }

第二种方式：

定时发邮件可以用Timer来设置时间，放在了Global.asax的Application_Start里面

using System.Net.Mail; 
using System.Timers; 
protected void Application_Start(object sender, EventArgs e) 
  { 
   Timer t = new Timer(60000);//设计时间间隔，如果一个小时执行一次就改为3600000 ，这里一分钟调用一次 
   t.Elapsed += new ElapsedEventHandler(t_Elapsed); 
   t.AutoReset = true; 
   t.Enabled = true; 
  } 
  private void t_Elapsed(object sender, ElapsedEventArgs e) 
  { 
   MailMessage message = new MailMessage(); 
   message.From = Messagefrom; 
   message.To.Add(MessageTo);    //收件人邮箱地址可以是多个以实现群发 
   message.Subject = MessageSubject; 
   message.Body = MessageBody; 
   message.IsBodyHtml = true;    //是否为html格式 
   message.Priority = MailPriority.High; //发送邮件的优先等级 
   SmtpClient sc = new SmtpClient(); 
   sc.Host = "smtp.sina.com";    //指定发送邮件的服务器地址或IP 
   sc.Port = 25;       //指定发送邮件端口 
   //sc.UseDefaultCredentials = true; 
   //sc.EnableSsl = true; 
   sc.Credentials = new System.Net.NetworkCredential(“**@**”, "密码"); //指定登录服务器的用户名和密码 
    sc.Send(message);  //发送邮件 
  }
