Doubt regarding System.windows.Form.Control

Hi all,

I have seen a code as shown below

Class Sample
    {
         AddSubPage("Title",new ServerControl());
         private void AddSubPage(string title, Control subPage)
         {

         }
    };
    Class ServerControl
    {
       public ServerControl()
       {
           InitializeComponent();
       }
    };

My doubt is regarding the second parameter.What is actually passing in the

second parameter.I know 'Control' is the base class of all controls in form.So how

to assign new ServerControl() to Control object.

'new ServerControl()' means just calling a constructor.(See the code).Then what is

actually passing here.

Thanks in advance

Your example is incomplete, the ServerControl class does not derive from anything so it has no base class. I'll assume you meant for it to derive from Control.

new ServerControl() will create an object of type ServerControl and pass it to the AddSubPage method. Since it is derived from Control it has an is a relationship. ServerControl is a Control. This is a basic object oriented concept, if you don't understand it then I would suggest learning OO before proceeding.
