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);
 29                XmlDocument xd = new XmlDocument();
 30                xd.LoadXml(sr.ReadToEnd());
 31                XmlNamespaceManager xnm = new XmlNamespaceManager(xd.NameTable);

 40                string monthsStr = xd.SelectSingleNode(renewal, xnm).InnerText;

 42
 43                int otherMonthNum = 0;
 44                string dateunit=null;

 52                        DateTime dtotherDate;
 53                        if (DateUnits.Equals("Days"))
 54                        {

 88                //    string content = emailContent + ", This " + otherMonthNum + " " + dateunit + " mails reminds ahead of time";
 89
 90                //  //  string returnValues = SendEmial(smtpHost, smtpName, smtpPass, to, title, content);
 91                //}
 92                if (ts.Days == 0 && xncommitteeAcion.InnerText.ToString().Equals(actionSates) && !xnsubmissionType.InnerText.ToString().Equals(submissionTypeValue.ToString()) && spli["SatesOfTimer"] == null)
 93                {

104                        spli.Update();
105                        spweb.Update();
106
107                    }
108                }
109                else if (ts.Days == 0 && xncommitteeAcion.InnerText.ToString().Equals(actionSates) && !xnsubmissionType.InnerText.ToString().Equals(submissionTypeValue.ToString()) && !spli["SatesOfTimer"].ToString().Equals(sateTime))
110                {

112                    string to = toemail;

116
117                    //add a listitem

121                        spli.Update();
122                        spweb.Update();
123                    }
124                }
125
126            }
127        }
128     
129        private string  SendEmial(string smtpHost, string smtpName, string smtpPass, string to, string title, string content)
130        {
131            MailAddress sendto = new MailAddress(to);
132            MailAddress sendForm = new MailAddress(smtpName);
133            MailMessage _mailMessage = new MailMessage(sendForm, sendto);
134            _mailMessage.Subject = title;
135            _mailMessage.Body = content;
136            _mailMessage.BodyEncoding = System.Text.Encoding.UTF8;
137            SmtpClient _smtpClient = new SmtpClient(smtpHost);

140
141            try
142            {
143                _smtpClient.Send(_mailMessage);
144                return "OK";
145            }
146            catch (Exception ex)
147            {
148                return ex.Message;   
149            }
150        }     
151

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        {
10
11        }
12        public override void FeatureActivated(SPFeatureReceiverProperties properties)
13        {
14            SPSite spsite = properties.Feature.Parent as SPSite;
15
16            foreach (SPJobDefinition job in spsite.WebApplication.JobDefinitions)
17            {
18                if (job.Name == MY_TASK)
19                    job.Delete();
20            }
21
22            EventCheckTimesSendEmail timer = new EventCheckTimesSendEmail(MY_TASK, spsite.WebApplication);
23
24            //时间写短点是为测试
25            SPMinuteSchedule schedule = new SPMinuteSchedule();
26            schedule.BeginSecond = 0;
27            schedule.EndSecond = 59;
28            schedule.Interval = 59;
29
30            timer.Schedule = schedule;
31            timer.Update();
32            
33        }
34
35        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
36        {
37            SPSite spsite = properties.Feature.Parent as SPSite;
38            foreach (SPJobDefinition job in spsite.WebApplication.JobDefinitions)
39            {
40                if (job.Name == MY_TASK)
41                    job.Delete();
42            }
43        }
44    }
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。
