how to call any method of Project from classlibrary?

I have Class Library Where a class of multithreading Of Producer and consumer based.

private void WorkDeQueue()
    {
        while (true)
        {
            string Url = null;
            lock (locker)
            {
                if (queueList.Count > 0)
                {
                    Url = queueList.Dequeue();
                    /* return if a null is found in the queue */
                    if (Url == null) return;
                }
            }
            if (Url != null)
            {
                /* if a job was found then process it */
                GetData(Url); //This Is a Meth开发者_运维百科od 
            }
            else
            {
                /* if a job was not found (meaning list is empty) then
                * wait till something is added to it*/
                wh.WaitOne();
            }
        }
    }

This GetData method has no body on that class. How can I call any method of my project in place of GetData.

I tried with factory Pattern and also with reflection, but both didn't work for me. So plz tell me how I can call any method of my project from here.

Not really a lot of info to go on, but I'd probably make GetData in to a delegate so you can just replace it with whatever is needed when you create the class instance. Something like: ' public class Class1 { public delegate void GetDataDelegate(string url); private event GetDataDelegate GetData;

    public Class1(GetDataDelegate getData)
    {
        GetData += getData;
    }

    //blah blah blah
}
