executing a c# function after each 24 hours

I have a c# function for producing thumbnail images, these images are displayed on web-pag开发者_高级运维e i.e ASP.net So how would i programtically call this back-end function let say everyday at 16:00 or at 3:00.

Write your code as a standalone console application - and then set up a scheduled task on the server to run your application at this time everyday.

If you want the task to run more than once a day you will have to set up a scheduled task for each time.

To set a scheduled task up go to Control Panel > Scheduled Tasks and then click on "Add Scheduled Task". This opens a wizard which guides you through the process:

1. Select your application
2. Give the task a name and select the frequency - you'll want Daily.
3. Assign the time and whether you want this task every day, on weekdays or every days. Also when you want the task to start.
4. Enter the credentials of the user account to run the application under. It would be best to set up a separate account for this.

Then you are done.

You can tweak the settings once it's set up.

Either write a windows service or schedule a job.

Another way to handle it is by using Quartz.NET. It's pretty powerful job-scheduling library. This answer talks about using it with asp.net.
