SharePoint 2010 自定义计时器(Timer Job)

1.使用Vs2010创建一个空SharePoint 项目(我的名字：SharePointCusTimer)，然后右击项目名添加一个类(我的名字：MyTimerJob.cs)，打开该类修改代码如下：(代码下载https://files.cnblogs.com/sygwin/SharePointCusTimer.rar)

View Code

using System;
using Microsoft.SharePoint;//必须命名空间
using Microsoft.SharePoint.Administration;

namespace SharePointCusTimer
{
    class MyTimerJob:SPJobDefinition
    {

        public MyTimerJob() : base() { }
        public MyTimerJob(SPWebApplication webApp)
            : base("MyTimerJob", webApp, null, SPJobLockType.ContentDatabase)
        {
            this.Title = "MyCustomTimerJob"; 
        }
        public override void Execute(Guid targetInstanceId)
        {
            SPWebApplication app = this.Parent as SPWebApplication;
            SPList announcements = app.Sites[0].RootWeb.Lists["民政局文档库"]; // get reference of the lists
            app.Sites[0].RootWeb.AllowUnsafeUpdates = true;

            //计时器定时要执行的动作。在指定文本文件里内容
            string Path = @"C:\test.txt";
            string Strings = string.Format("列表标题{0}----{1}", announcements.Title, DateTime.Now.ToString());
            System.IO.StreamWriter f2 = new System.IO.StreamWriter(Path, true, System.Text.Encoding.UTF8);
            f2.WriteLine(Strings);
            f2.Close();
            f2.Dispose();
        }
    }
}

注意命名空间的引入。

2.右击Feature文件，选择添加功能，然后右击新添的Feature，选择添加事件接收器。将FeatureActivated和FeatureDeactivating里的代码修改如下：

View Code

// 取消对以下方法的注释，以便处理激活某个功能后引发的事件。
        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                SPWebApplication webApp = null;
                SPSite site = null;

                //webApp = properties.Feature.Parent as SPWebApplication;//老外是这么获取的，激活时报错
                site = properties.Feature.Parent as SPSite;
                webApp = site.WebApplication;

                //make sure the job isn't already registered
                foreach (SPJobDefinition job in webApp.JobDefinitions)
                    if (job.Name == "MyTimerJob") job.Delete();

                MyTimerJob myJob = new MyTimerJob(webApp);
                SPMinuteSchedule schedule1 = new SPMinuteSchedule();//这里是按分钟执行，具体参数说明参考msdn
                schedule1.BeginSecond = 0;
                //schedule1.EndSecond = 10;
                schedule1.Interval = 1;

                myJob.Schedule = schedule1;
                myJob.Update();
            });
        }
        // 取消对以下方法的注释，以便处理在停用某个功能前引发的事件。
        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            SPWebApplication webApp = null;
            SPSite site = null;

            site = properties.Feature.Parent as SPSite;
            webApp = site.WebApplication;

            foreach (SPJobDefinition job in webApp.JobDefinitions)
                if (job.Name == "MyTimerJob") job.Delete();
        }
