Passing a callback function to another class

Question

I\'m basically trying to pass a method to another class to be called later, but can\'t quite figure this out in C# (I\'m still too used to Objective-C).

public c         


        

Answer 1

public class Class1
    {

        private void btn_click(object sender, EventArgs e)
        {
            ServerRequest sr = new ServerRequest();
            sr.Callback += new ServerRequest.CallbackEventHandler(sr_Callback);
            sr.DoRequest("myrequest");
        }

        void sr_Callback(string something)
        {

        }


    }

    public class ServerRequest
    {
        public delegate void CallbackEventHandler(string something);
        public event CallbackEventHandler Callback;   

        public void DoRequest(string request)
        {
            // do stuff....
            if (Callback != null)
                Callback("bla");
        }
    }
