I was reading http://stackoverflow.com/questions/1511798/threading-from-within-a-class-with-static-and-non-static-methods and I am in a similar situation.

I have a static method that pulls data from a resource and creates some runtime objects based on the data.

static class Worker{
    public static MyObject DoWork(string filename){
        MyObject mo = new MyObject();

        // ... does some work

        return mo;
    }
}

The method takes awhile (in this case it is reading 5-10mb files) and returns an object.

I want to take this method and use it in a multiple thread situation so I can read multiple files at once. Design issues / guidelines aside, how would multiple threads access this code?

Let's say I have something like this...

class ThreadedWorker {
    public void Run() {
        Thread t = new Thread(OnRun);
        t.Start();
    }

    void OnRun() {
        MyObject mo = Worker.DoWork("somefilename");

        mo.WriteToConsole();
    }
}

Does the static method run for each thread, allowing for parallel execution?
