Task Scheduler, Periodic execution in asp.net c# by using Thread

In asp.net there are needs for performing few activities periodically.

For that we can use some class libraries or third party component to schedule a task or function to execute periodically.

Recently i found following simplest way to execute periodically any code.

Suppose you have a class and routine as follow in App_Code/CS,

public class ClassABC


public static void SomeFunctionToRunPeriodically()


try {

System.IO.File.WriteAllText(System.Web.Hosting.HostingEnvironment.MapPath(“~/LatestRunSaved.txt”), “Last Run of function at : ” + DateTime.Now.ToString() + Environment.NewLine);


catch (Exception ex) { string t = ex.Message; }


SomeFunctionToRunPeriodically(); //calling self after interval


public ClassABC()

{ // // TODO: Add constructor logic here // }



If you notice in above function then its calling to itself after interval. Now in global application file ‘global.asax’ inside application start event use following lines to create a new thread based call to a function above.

void Application_Start(object sender, EventArgs e)


System.Threading.Thread obj = new System.Threading.Thread(new System.Threading.ThreadStart(ClassABC.SomeFunctionToRunPeriodically));

obj.Name = “AnyTestName”;

obj.IsBackground = true;



New thread based function call will run until your application is running in IIS process, It is a background process. Other routine things on site will work normally without problem.
