but i don't know how to create win services.

In Visual Studio Pro and above:

File => New Project => Visual C# => Windows => Windows Service

and see the walkthrough here or howto here.

The most important thing is that during the service startup you only do things like spawn a worker thread. You don't do the real processing in there (otherwise it will timeout when starting the service, and Windows will kill it). Oh, and check what working-folder the service starts with - you might find it is the system folder.

You might want to take a look at TopShelf (http://code.google.com/p/topshelf/), which is as described by their website:

"Topshelf is a lightweight framework for building Windows services using the .NET framework. The key goal of Topshelf is limiting the surface area of service-related code within the application."

It might save you some time when it comes to simplifying the development and deployment of your service.
