Question

I am fairly new to .Net, and I am clearly doing something wrong here. In my base abstract class, I have the following delegate:

public delegate bool DEnqueue(ref IPCPriorityMessage item, byte priority);

… and the following method declaration:

public abstract DEnqueue Enqueue();

In my instance class, I have the following:

public override DEnqueue Enqueue;

I point Enqueue to the applicable local method. I can only get this to work if I don’t use inheritance or don’t use delegates.

My exact objectives are:

1. Use the base abstract class to force the design pattern. Instances must contain a method Engueue().
2. Use delegates in the instance class so that the applicable private enqueue() method is called when the public Enqueue() method is called.

How do I do this? I tried using interfaces, but has basically the same problem.

NOTE: I only know at runtime which private enqueue() to use, hence my use of delegates.

Looks like you’re looking for the Template Method Pattern. No need to use delegates.
