Call a user control method on a UserControl object

I have a user control class that is derived from UserControl

[ComVisible(true)]
public class MyUserControl : UserControl

it contains a method I called Initialize() : public void Initialize() In another class, I need to use a MyUserControl, but I would like to declare and use generic UserControl objects. That way, I'll be able to reuse this class even with a new and different user control (let's say MyUserControl2).

So I declared a member of this class as 

private static UserControl _userControl;

here is the constructor

public CTPManager(UserControl userControl, string Title, MsoCTPDockPosition Position)
{
    //stuff

    _userControl = userControl;
    _title = Title;
    _position = Position;
}

First question : is it possible to later instantiate the class with this :

MyUserControl newControl = new MyUserControl();
CTPManager newCTP = new CTPManager(newControl, "window title", etc.);

If so, can I call Initialize() method of MyUserControl newControl since I only need to do these two calls inside the CTPManager class :

CustomTaskPaneFactory.CreateCustomTaskPane(typeof(UserControl), _title, _EXCELApp.ActiveWindow)); //-> this one will be ok because of CreateCustomTaskPane signature
_userControl.Initialize //-> that is what I would like to be able to do !

Thank you very much for any answers or advice

Create an interface with the Initialize() method. Implement the interface. Save the control in CTPManager as that interface. Or, if you want to store it as a UserControl, then you could cast it to the type you want:

var init = (InitializerInterface)_userControl;
if (init != null) ...

You can use MethodInfo:

//Get the method information using the method info class
 MethodInfo mi = _userControl.GetType().GetMethod("Initialize");

//Invoke the method
mi.Invoke(_userControl, null);
