ASP. NET MVC Plan task implementation method (timed to perform a function)

It is more common to perform a task regularly in a system, such as a typical example of a department reporting data to a parent department on a regular basis, and the following is a simple way to implement a timed execution of a feature in. NET MVC.

1, first modify the Glocal.asax file, at the bottom of the Application_Start method to add:

 //  define timer   1000 means 1 seconds  System.Timers.Timer MyTimer = new  System.Timers.Timer (1000   // taskaction.setcontent represents the method to invoke  mytimer.elapsed + = new   System.Timers.ElapsedEventHandler (taskaction.setcontent); mytimer.enabled  = true  ;mytimer.autoreset  = true ; 

The above code runs when the application starts

2. Add the following method to the Glocal.asax file:

voidSession_End (Objectsender, EventArgs e) {    //The following code is critical to resolve an issue with automatic collection of IIS application poolsSystem.Threading.Thread.Sleep ( +); //trigger event, write prompt messagetaskaction.setcontent (); //Set your web address here and you can point to any of your ASPX pages or even nonexistent pages to inspire Application_Start//use your own URL    stringURL ="http://localhost:3813"; System.Net.HttpWebRequest myhttpwebrequest=(System.Net.HttpWebRequest) System.Net.WebRequest.Create (URL); System.Net.HttpWebResponse Myhttpwebresponse=(System.Net.HttpWebResponse) myhttpwebrequest.getresponse (); System.IO.Stream Receivestream= Myhttpwebresponse.getresponsestream ();//get write-back byte stream//The code that runs at the end of the session. //Note: The Session_End event is raised only if the sessionstate mode in the Web. config file is set to InProc. //if the session mode is set to StateServer//or SQL Server, the event is not raised. }

3, create the above two methods to use the class:

 Public Static classtaskaction{Private Static stringContent =""; /// <summary>    ///where the output information is stored. /// </summary>     Public Static stringContent {Get{returntaskaction.content;} Set{Taskaction.content + ="<div>"+ Value +"</div>"; } }    /// <summary>    ///method of the Timer delegate task invocation/// </summary>    /// <param name= "source" ></param>    /// <param name= "E" ></param>     Public Static voidSetContent (Objectsource, Elapsedeventargs E) {        if(DateTime.Now.ToString ("HH:mm:ss") =="11:35:00")        {            //Here you write the code that you execute regularlyContent = DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss"+"it's off duty! "); }    }    /// <summary>    ///methods to invoke when applying pool reclamation/// </summary>     Public Static voidsetcontent () {Content="END:"+ DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss"); }}
