Create Cron job to run after x hours

I'm using hangfire for scheduling jobs and creating recurring job as:

RecurringJob.AddOrUpdate(() => BackGroundJobManager.FirstJob(), Cron.Daily(4));

This runs the job daily at 4 AM. How can I configure a cron job to run after every 4 hours.

Solution

  • The cron expression to schedule something every four hours is e.g.:

    0 */4 * * *

    You could build that expression with Cron.HourInterval(4), but it seems to be deprecated. Since those methods just return the cron expression as a string, you could just build your own and use that instead.
