This pattern is particularly used when a system is very complex or difficult to understand and has multiple subsystems.<\/p>\n<h2>Let\u2019s understand with an example<\/h2>\n<p>This is the interface specific to the burger.<br \/>\n<code>public interface IBurger {<br \/>\n    void GetVegBurger();<br \/>\n    void GetNonVegBurger();<br \/>\n} <\/code><\/p>\n<p>This is a burger provider class which will get burgers for their clients. Here methods can have other private methods which the client is not bothered about.<br \/>\n<code>public class BurgerProvider: IBurger {<br \/>\n    public void GetNonVegBurger() {<br \/>\n        GetNonVegToppings();<br \/>\n        Console.WriteLine(\"Getting Non Veg Burger.\");<br \/>\n    }<br \/>\n    public void GetVegBurger() {<br \/>\n        Console.WriteLine(\"Getting Veg Burger.\");<br \/>\n    }<br \/>\n    private void GetNonVegToppings() {<br \/>\n        Console.WriteLine(\"Getting Non Veg Burger Toppings.\");<br \/>\n    }<br \/>\n}<\/code><\/p>\n<p>Similarly, this is the interface specific for the bread.<br \/>\n<code>public interface IBread {<br \/>\n    void GetGarlicBread();<br \/>\n    void GetCheesyGarlicBread();<br \/>\n}<\/code><br \/>\nAnd this is a bread provider class.<br \/>\n<code>public class BreadProvider: IBread {<br \/>\n    public void GetGarlicBread() {<br \/>\n        Console.WriteLine(\"Getting Garlic Bread.\");<br \/>\n    }<br \/>\n    public void GetCheesyGarlicBread() {<br \/>\n        GetCheese();<br \/>\n        Console.WriteLine(\"Getting Cheesy Garlic Bread.\");<br \/>\n    }<br \/>\n    private void GetCheese() {<br \/>\n        Console.WriteLine(\"Getting Cheese.\");<br \/>\n    }<br \/>\n}<\/code><br \/>\nBelow is the restaurant fa\u00e7ade class, which will be used by the client to order different burgers or breads.<br \/>\n<code>public class RestaurantFacade {<br \/>\n    private IPizza _PizzaProvider;<br \/>\n    private IBread _BreadProvider;<br \/>\n    public RestaurantFacade() {<br \/>\n        _PizzaProvider = new BurgerProvider();<br \/>\n        _BreadProvider = new BreadProvider();<br \/>\n    }<br \/>\n    public void GetNonVegPizza() {<br \/>\n        _PizzaProvider.GetNonVegBurger();<br \/>\n    }<br \/>\n    public void GetVegPizza() {<br \/>\n        _PizzaProvider.GetVegBurger();<br \/>\n    }<br \/>\n    public void GetGarlicBread() {<br \/>\n        _BreadProvider.GetGarlicBread();<br \/>\n    }<br \/>\n    public void GetCheesyGarlicBread() {<br \/>\n        _BreadProvider.GetCheesyGarlicBread();<br \/>\n    }<br \/>\n}<\/code><br \/>\nFinally, below is the main method of our program,<br \/>\n<code>void Main() {<br \/>\n    Console.WriteLine(\"----------------------CLIENT ORDERS FOR BURGERS----------------------------\\n\");<br \/>\n    var facadeForClient = new RestaurantFacade();<br \/>\n    facadeForClient.GetNonVegBurger();<br \/>\n    facadeForClient.GetVegBurger();<br \/>\n    Console.WriteLine(\"\\n----------------------CLIENT ORDERS FOR BREAD----------------------------\\n\");<br \/>\n    facadeForClient.GetGarlicBread();<br \/>\n    facadeForClient.GetCheesyGarlicBread();<br \/>\n}<\/code><\/p>\n<p><small><em>StudySection has a long list of certification exams that it offers through its online platform.
