How to execute code in c# service one time per day

Question

So here's my problem, I need to do a c# service running on a server who's getting file on ftp one time per day at 3am. I think that I can do it with a thread.sleep() or by compare the DateTime.Now with 3am....

Do you have better solution?

Thank you very much for your help!

Answer 1

If you are expecting a file every night, instead of worrying about when it arrives, just get an event fired when it does.

Look at:

System.IO.FileSystemWatcher

File System Watcher on MSDN

Answer 2

Write a console app or equivalent, and use the Windows Scheduler (or whatever it's called nowadays...) to run it daily.

Answer 3

System.Threading.Timer might work out for you.

Answer 4

Much better solution, let windows do it for you using Scheduled Tasks.

If it only needs to be executed once a day, then I would go for this. Even Google does it ;)

EDIT:

To answer the comment, it is as Fredrik has said. It is an Advanced Option, which you can open as the task is set up, containing a checkbox called: "Run only if logged on", which is false to begin with.

Answer 5

For a flexible solution, you could use this. It's not a Windows service, but you could easily incorporate it into one. Or you might consider Quartz.NET which is reputed to be industrial strength (the Java version certainly is).

Answer 6

Why not set this up to run as a scheduled task. Have it execute and then exit. Set up Windows to start the process as a scheduled task at 3:00 AM daily.
