Use like this using System; using System.Threading; namespace ScheduleService { class Program { static void Main( string [] args) { ScheduleService scheduleService = new ScheduleService(); scheduleService.ScheduleServiceInMin( "10" ); scheduleService.ScheduleServiceOnceADay( "10:00" ); } } public class ScheduleService { private System.Threading.Timer SchedularOnceADay, SchedularInMin; readonly string ScheduledTime = "10:00" , IntervalMinutes = "10" ; /// /// To call a service at a particular time of the day. /// /// Service running in a particular time of the day like ScheduledTime=10:00(Specify time in HH:mm). /// It means this service will run at 10:00 of every day public void ScheduleServiceOnceADay( string ScheduledTime) { try { SchedularOnceADay = new System.Threading.Timer( new TimerCallback(SchedularCallbackOnceADay)); //Set the Default Time. DateTime scheduledTime = DateTime.MinValue; //Get the Scheduled Time from AppSettings. scheduledTime = DateTime.Parse(ScheduledTime); if (DateTime.Now > scheduledTime) { //If Scheduled Time is passed set Schedule for the next day. scheduledTime = scheduledTime.AddDays(1); } TimeSpan timeSpan = scheduledTime.Subtract(DateTime.Now); string schedule = string .Format( "{0} hour(s) {1} minute(s) {2} second(s)" , timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds); Console.WriteLine( "Service scheduled to run after: " + schedule); //Get the difference in Minutes between the Scheduled and Current Time. int dueTime = Convert.ToInt32(timeSpan.TotalMilliseconds); //Change the Timer's Due Time. SchedularOnceADay.Change(dueTime, Timeout.Infinite); } catch (Exception ex) { Console.WriteLine( string .Format( "Error: {0} - {1}" , ex.Message, ex.StackTrace)); } } private void SchedularCallbackOnceADay( object e) { //TODO // Your Code to run once a day //Run the SchedularService at a fixed interval of time. ScheduleServiceOnceADay(ScheduledTime); } /// /// To call a service at regular interval of time. /// /// Service running interval time in Minutes like modeValue=10. public void ScheduleServiceInMin( string modeValue) { try { SchedularInMin = new System.Threading.Timer( new TimerCallback(SchedularCallbackInMin)); //Set the Default Time. DateTime scheduledTime = DateTime.MinValue; //Get the Interval in Minutes from AppSettings. int intervalMinutes = Convert.ToInt32(modeValue); //Set the Scheduled Time by adding the Interval to Current Time. scheduledTime = DateTime.Now.AddMinutes(intervalMinutes); if (DateTime.Now > scheduledTime) { //If Scheduled Time is passed set Schedule for the next Interval. scheduledTime = scheduledTime.AddMinutes(intervalMinutes); } TimeSpan timeSpan = scheduledTime.Subtract(DateTime.Now); string schedule = string .Format( "{0} hour(s) {1} minute(s) {2} second(s)" , timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds); Console.WriteLine( "Service scheduled to run after: " + schedule); //Get the difference in Minutes between the Scheduled and Current Time. int dueTime = Convert.ToInt32(timeSpan.TotalMilliseconds); //Change the Timer's Due Time.

ScheduleServiceInMin(IntervalMinutes); } } }

Hey, try the below code. public class ScheduleService { private System.Threading.Timer SchedularOnceADay, SchedularInMin; readonly string ScheduledTime = "10:00" , IntervalMinutes = "10" ; /// /// To call a service at a particular time of the day. /// /// Service running in a particular time of the day like ScheduledTime=10:00(Specify time in HH:mm). /// It means this service will run at 10:00 of every day public void ScheduleServiceOnceADay( string ScheduledTime) { try { SchedularOnceADay = new System.Threading.Timer( new TimerCallback(SchedularCallbackOnceADay)); //Set the Default Time.

Hey if you using Winforms then you can also use timer control. Check the below links. https://www.c-sharpcorner.com/UploadFile/mahesh/C-Sharp-timer/ https://www.c-sharpcorner.com/article/timer-in-C-Sharp/ https://stackoverflow.com/questions/1142828/add-timer-to-a-windows-forms-application

Hey Ahmet Taha you can use the given code in c# winforms also.

Ahmet Taha · Answer

ok sir thanks a lot but if its okay that i want to see the queuing system in c# that in c#.net windows form? :-)

Ahmet Taha · Answer

first at all thanks a lot for your reply to my concern , yes sir exactly like that a programe for a interval of time.

Laxmidhar Sahoo · Answer

hi Would you like to run a programe for a interval of time or something else ?
