Calling a function periodically c#

Question

I am sending mails from my codes, for some activities.

But some mails may fail due to some or other reason.

I am keeping details of all such failed mails in a table.

Now my plan is to periodically check that table and resend mails if the table contain failed mails.

Or in other words,I want to call a method SentFailedMails() in every 12 hours.

How can I do this is c#

My application is a WCF service,Hosted on IIS

I don't think there is such things in mvc.It's better you write windows service for this task and then install on your webserver to resend email — Arash, Sep 02 '15 at 08:35
Perhaps. Then again, the last thing the world wants is _another_ Windows Service with a built-in scheduling component. Consider using the standard _Task Scheduler_ as rene mentioned instead and have it run your regular non-service .EXE. Plus it's kinder to puppies — MickyD, Sep 02 '15 at 08:37
@KuttanSujith Great! What _sort_ of WCF service? Where is it hosted? _IIS? WinForms? WPF? Custom host .exe?_ A WCF Service _inside a Windows Service_? — MickyD, Sep 02 '15 at 08:40
You can mark the temporarily failed emails in a table in database. Now you can write another windows service which can have a timer to resend your emails. Or you can write a simple console application for re-sending emails and call this application from Windows Task Schedular — M_Idrees, Sep 02 '15 at 08:46

Create a very simple console application that do the task (move your SentFailedMails() method to this application and execute it on run).

Place the exe file for the console application in a folder of your server.

Use Windows Task Scheduler to schedule the exe file execution for every 12 hours or on any specific time.

Windows Task Scheduler is a ready to use thing from windows. You can set it to execute a program in specific times of the day. Non developer can use it. [link](http://www.7tutorials.com/how-create-task-basic-task-wizard) Workflow foundation is more towards developing your own scheduler. I think. – Ppp Sep 02 '15 at 11:49

You might want to use a scheduler like Quartz.net

You can use a threading.timer and set it to 12:00:00 then give it your mail method to execute . Don't forget about the dispatcher to change thread though.
