How to add a delegate to an interface C#

I need to have some delegates in my class.

I'd like to use the interface to "remind" me to set these delegates.

How to?

My class look like this:

public class ClsPictures : myInterface
{
    // Implementing the IProcess interface
    public event UpdateStatusEventHandler UpdateStatusText;
    public delegate void UpdateStatusEventHandler(string Status);

    public event StartedEventHandler Started;
    public delegate void StartedEventHandler();
}

I need an interface to force those delegates:

public interface myInterface
{
   // ?????
}
