Abstract Factory Pattern-Creational Patterns

Posted By: Rahul     Posted Date: January 19, 2010    Points: 2   Category :Patten/Practices
The Factory pattern allowed us to decouple our client from an object which it uses. The Abstract Factory pattern extends this idea to manage separate families of objects.

A runtime selection, or configuration option, in our client could decide which family of objects is to be used. The Abstract Factory pattern allows us to write generic code to instantiate and use the family objects regardless of which family is chosen at runtime. The pattern also helps us enforce a rule where objects from just the chosen family are used uniformly by the client.

Abstract Factory Design Pattern (Sample in C# and VB .NET)

An abstract factory provides an interface for creating families of related objects without specifying their concrete classes. Sometimes one wants to construct an instance of one of a suite of classes, deciding between the classes at the time of instantiation. In order to avoid duplicating the decision making everywhere an instance is created, we need a mechanism for creating instances of related classes without necessarily knowing which will be instantiated.

Prototype Pattern-Creational Patterns in C#

The Prototype Pattern approaches the creation of the objects that our client will use by cloning instances from prototypes as required. This achieves the general aim of decoupling the client from the objects that it will use, but also adds some advantages unique to the Prototype pattern.

Singleton Pattern-Creational Patterns

The Singleton pattern is a specialist creational pattern as it's primary focus is to facilitate a single shared instance of our object rather than to decouple our client from the object's implementation as with the other creational patterns.

Provide an interface for creating families of related or dependent objects without specifying their concrete classes

Factory Pattern in asp.net

The job of the Factory design pattern is to create concrete sub classes. You can see the Factory design pattern used throughout the .NET Framework.

The essence of the Factory Pattern is to "Define an interface for creating an object, but let the subclasses decide which class to instantiate. The Factory method lets a class defer instantiation to subclasses." Factory methods encapsulate the creation of objects. This can be useful if the creation process is very complex, for example if it depends on settings in configuration files or on user input.

The Factory Design Pattern

Software architects generally think in terms of high-level abstractions rather than low-level programming details. Representing a system in terms of high-level abstractions promotes understanding of the system and reduces its perceived complexity. One such set of abstractions is software design patterns. They have been successfully applied in the past to simplify and solve recurring problems in software design.

GOF Creational Design Patterns with C#

The GOF design patterns help address the following challenges :

design ready to accommodate change & growth

design flexible systems which come ready to handle reconfiguration and run time tailoring

code in manner to facilitate reuse during the development and extension phases ... ie. both external and internal reuse, so that we are rewarded by efficiencies as the project progresses, coming from investments made earlier in the project.

implement change in a way that doesn't overly shorten the system's useful lifespan

Design Patterns - Using the State Pattern in C#

What is the State Pattern?

The State Pattern is a behavioral pattern that can be used to alter the behavior of an object at run time. As the state of an object changes, the functionality of the object can change drastically. This change of behavior is hidden from the Client and the Client interfaces with a wrapper object known as the Context. The State Pattern is a dynamic version of the Strategy Pattern.

Singleton Pattern and Abstract Class


I know what Singleton Pattern means and Abstract class means.

What I wanted to know was how would this apply to real world.

Could anyone give me any good example or simple explanation.

Say I have a simple website, why would I use any of the above if any.

Why would it simplify my architechture.

Thanks in advace.

Design Patterns: Simplify Distributed System Design Using the Command Pattern, MSMQ, and .NET


Service-oriented architecture is a great framework when you need to perform distributed computing tasks over the Internet. But when you want to perform processing inside your local network, a different solution may provide a better fit. That solution, based on the Command pattern, uses Windows services and Microsoft Message Queuing to implement a queued system that meets your needs better than a service-oriented solution. This article explains how to build it.

Factory pattern


I have been given this assignment to be completed and I am stuck at the first step. Here are the requirements. I have 4 files:






Parent is abstract class 

Modify child1.cs and child2.cs so that they are nested classes within Parent class

Make sure child1 and child2 classes can only be created by Parent class 

Create a static method in Parent class which takes string parameter and if string is 'Child1' return child1 else return child2

Method in the form1.cs that creates and instance of parent class.


I am not sure how to make them as nested classes ...if I need to create partial classes then how do I do that.

How do I make sure that child classes can only be created by parent class?



Factory pattern logic



I am creating a simple CMS for learning purposes. It has a DAL, BLL and UI. The DAL contains non static methods which are accessed in the BLL layer.

I have a factory pattern which creates instances of the DAL methods like this:

    public class Factory
        public static T GetInstance<T>() where T : new()
            return new T();


And they are accessed in the BLL like this:

   public void Save(Article article)
            ArticleData artDate = GeepyFactory.GetInstance<ArticleData>();


My question is, what additional logic should/usually go into the Factory class to make it favourable/a better solution over standard instantiation of a class like this ArticleDAL artDal = new ArticleDal(); ??

Dialogs and ViewModel - Using Tasks as a Pattern

The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.
