I need help in c# about file scanning in c#. I want to scan all files or from specific path in background if application is in running mode. Scanning should start after every 10 min.......

This isn't a software writing service. What have you done so far? What problems or errors are you getting?

I did a quick google and found quite a lot of info on running background processes, Have a look at the two links below and see if they help at all (i typed "running background processes in C#" into google)

So....do you understand how threads, threadpools, or background workers work? Do you understand file IO and parsing? Or do you just want us to do the project for you (lol)?

What do you intend to do during the scan?
If you are looking for changes then you could use a FileSystemWatcher to do the "scanning" for you.

Ok, then a FileSystemWatcher will do just that for you. (Google it)
