It will provide you an abstraction to implement functionality of the complex subsystem. What is the Facade Design Pattern in C#? The facade design pattern is a creational design pattern, i.e., falls under the creational design pattern group and can be used to represent a gateway to a subsystem. This article explains what is facade pattern and how to implement facade design pattern in C#. If we try to understand this in simpler terms, then we can say that a room is a façade and just by looking at it from outside the door, one can not predict what is inside the room and how the room is structured from inside. As per the GOF definition, the Façade Design Pattern states that you need to provide a unified interface to a set of interfaces in a subsystem. Facade is a structural design pattern that provides a simplified interface to a library, a framework, or any other complex set of classes. Facade is a structural design pattern that provides a simplified (but limited) interface to a complex system of classes, library or framework. If we try to understand this in simpler terms, then we can say that a room is a façade and just by looking at it from outside the door, one can not predict what is inside the room and how the room is structured from inside. Facade pattern hides the complexities of the system and provides an interface to the client using which the client can access the system. Facade design pattern is useful when you want to handle a complex system which has multiple independent subsystems. The Façade Design Pattern defines a higher-level interface that makes the subsystem easier to use. Facade Design Pattern in C# with Examples. Facade design pattern provides abstracted … Discussion. In this article, I am going to discuss the Facade Design Pattern in C# with some examples. Facade pattern in C#. .NET Optimized code in C#. The .NET optimized code demonstrates the same real-world situation as above but uses modern, built-in .NET features, such as, generics, reflection, object initializers, automatic properties, etc. The Facade Design Pattern falls under the category of Structural Design Pattern.As part of this article, we are going to discuss the following pointers. .NET Optimized code in C#. The Facade Design Pattern falls under the category of Structural Design Pattern.As part of this article, we are going to discuss the following pointers. Facade Design Pattern in C++ Back to Facade description Facade design pattern demo. A common design goal is to minimize the communication and dependencies between subsystems. Facade design pattern comes under structural design pattern category of Gang of four (GoF) design patterns. You can find an example on our Singleton pattern page. Facade Design Pattern. Discussion. Facade is a part of Gang of Four design pattern and it is categorized under Structural design patterns.
