sharepoint计时器（定时发邮件）

做这个定时器Andrew Connell的博客给我很大的帮助。里面有所有的源代码，思路也很清晰
http://www.andrewconnell.com/blog/articles/CreatingCustomSharePointTimerJobs.aspx

主要是继承SpJobDefinition,改写几个构造体和Execute的方法.基本代码的模式就是这个样子：
下面是自己的一段代码有些凌乱：

  1 class EventCheckTimesSendEmail : SPJobDefinition
  2    {
  3        public EventCheckTimesSendEmail() : base() { }
  4        public EventCheckTimesSendEmail(string _timername, SPWebApplication _wp)
  5            : base(_timername, _wp, null, SPJobLockType.ContentDatabase)
  6        {
  7            this.Title = "SendEmailEventCheckTime";
  8        }
  9        public override void Execute(Guid targetInstanceId)
 10        {
 11//这些参数都是从OwsTimer.exe.config中读取的。这个文件是自己添加的。参数也可以自己写的。
 12            SPWebApplication webApplication = this.Parent as SPWebApplication;
 13            SPContentDatabase contentDb = webApplication.ContentDatabases[targetInstanceId];
 14            string splistname = ConfigurationManager.AppSettings.Get("ListName");
 15            string smtpHost = ConfigurationManager.AppSettings.Get("SmtpHost");
 16            string smtpName = ConfigurationManager.AppSettings.Get("SmtpName");
 17            string smtpPass = ConfigurationManager.AppSettings.Get("SmtpPass");
 18            string emailTitle = ConfigurationManager.AppSettings.Get("EmailTitle");
 19            string emailContent = ConfigurationManager.AppSettings.Get("EmailContent");                             
 20            string spwebName = ConfigurationManager.AppSettings.Get("SpwebName");
 21            SPWeb spweb = contentDb.Sites[0].AllWebs[spwebName];
 22            DateTime dt;           
 23            foreach (SPListItem spli in spweb.Lists[splistname].Items)
 24            {
 25                string spff = null;
 26                
 27                Stream stream = spli.File.OpenBinaryStream();
 28                StreamReader sr = new StreamReader(stream);

 30                xd.LoadXml(sr.ReadToEnd());

 40                string monthsStr = xd.SelectSingleNode(renewal, xnm).InnerText;
 41                string toemail = itemEmail.ToString();
 42
 43                int otherMonthNum = 0;
 44                string dateunit=null;
 45                if (monthsStr.Equals("Other"))
 46                {
 47                    if (xd.SelectSingleNode(otherRenewal,xnm).InnerText.ToString().Trim() != null)
 48                    {
 49                        string DateUnits = xd.SelectSingleNode(ItemDateUnits, xnm).InnerText.ToString();

 77                    string[] monthss = monthsStr.ToString().Trim().Split('M');

 79                    DateTime dtMoth = dtNow.AddMonths(otherMonthNum);
 80                    dateunit = "Months";
 81                    ts = (dtMoth.Date - dt.Date);

 93                {

 96                    string title = emailTitle;

                    }
                }
                else if (ts.Days == 0 && xncommitteeAcion.InnerText.ToString().Equals(actionSates) && !xnsubmissionType.InnerText.ToString().Equals(submissionTypeValue.ToString()) && !spli["SatesOfTimer"].ToString().Equals(sateTime))
                {
                    //Send Email
                    string to = toemail;
                    string title = emailTitle;
                    string content = emailContent + ", This " + otherMonthNum + " " + dateunit + " mails reminds ahead of time";

                        spli.Update();
                        spweb.Update();
                    }
                }

            }
        }
     
        private string  SendEmial(string smtpHost, string smtpName, string smtpPass, string to, string title, string content)
        {
            MailAddress sendto = new MailAddress(to);
            MailAddress sendForm = new MailAddress(smtpName);
            MailMessage _mailMessage = new MailMessage(sendForm, sendto);
            _mailMessage.Subject = title;
            _mailMessage.Body = content;
            _mailMessage.BodyEncoding = System.Text.Encoding.UTF8;
            SmtpClient _smtpClient = new SmtpClient(smtpHost);
            _smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;                    
            _smtpClient.Credentials = new System.Net.NetworkCredential(smtpName, smtpPass);

            try
            {
                _smtpClient.Send(_mailMessage);
                return "OK";
            }
            catch (Exception ex)
            {
                return ex.Message;   
            }
        }     

另外一个类就是：

 1 class EventCheckTimersInstallerSendEmail : SPFeatureReceiver
 2    {
 3        const string MY_TASK = "EventCheckTimesSendEmail";
 4        public override void FeatureInstalled(SPFeatureReceiverProperties properties)
 5        {
 6
 7        }
 8        public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
 9        {

        }
        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            SPSite spsite = properties.Feature.Parent as SPSite;

            foreach (SPJobDefinition job in spsite.WebApplication.JobDefinitions)
            {
                if (job.Name == MY_TASK)
                    job.Delete();
            }

            EventCheckTimesSendEmail timer = new EventCheckTimesSendEmail(MY_TASK, spsite.WebApplication);

            //时间写短点是为测试
            SPMinuteSchedule schedule = new SPMinuteSchedule();
            schedule.BeginSecond = 0;
            schedule.EndSecond = 59;
            schedule.Interval = 59;

            timer.Schedule = schedule;
            timer.Update();
            
        }

        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            SPSite spsite = properties.Feature.Parent as SPSite;
            foreach (SPJobDefinition job in spsite.WebApplication.JobDefinitions)
            {
                if (job.Name == MY_TASK)
                    job.Delete();
            }
        }
    }

接下来就是部署这个写好的定时器。
用Stsadm.exe来部署

代码写完了以后，还要写一个Feature，这个Feature比较简单，就一个XML文件

Feature.xml：

<?xml version="1.0" encoding="utf-8" ?>

<Feature xmlns="http://schemas.microsoft.com/sharepoint/"

         Id="1F481C17-4FDA-4919-A64A-EAE5C1301B4B"

         Title="Image Validation Checker"

         Description="If any images in the top level site colleciton images are expiring soon,email relative person."

         Scope="Site"

         Hidden="TRUE"

         Version="1.0.0.0"

         ReceiverAssembly="TimerJobControl, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f2aef6a9088f714f"

ReceiverClass="TimerJobControl.ImageValidationCheckerJobInstaller">

</Feature>

剩下的就是把feature装好就好了，假如代码没有出错的话。

至于怎么Debug这个程序，走以下步骤
把Assembly DLL放到GAC

1. 命令行：iisreset
2. 先Deactivate feature, 然后activate feature.
3. 命令行：net stop SPTimerV3
4. 命令行：net start SPTimerV3
5. Visual Studio: Attach to process: OWSTIMER.EXE

 

这样就OK了。
