.NET Design Patterns

By: Praseed Pai, Shine Xavier

Overview of this book

Knowing about design patterns enables developers to improve their code base, promoting code reuse and making their design more robust. This book focuses on the practical aspects of programming in .NET. You will learn about some of the relevant design patterns (and their application) that are most widely used. We start with classic object-oriented programming (OOP) techniques, evaluate parallel programming and concurrency models, enhance implementations by mixing OOP and functional programming, and finally to the reactive programming model where functional programming and OOP are used in synergy to write better code. Throughout this book, we’ll show you how to deal with architecture/design techniques, GoF patterns, relevant patterns from other catalogs, functional programming, and reactive programming techniques. After reading this book, you will be able to convincingly leverage these design patterns (factory pattern, builder pattern, prototype pattern, adapter pattern, facade pattern, decorator pattern, observer pattern and so on) for your programs. You will also be able to write fluid functional code in .NET that would leverage concurrency and parallelism!

Preface

A quick foray into the .NET Reflection API


When we write non-trivial software that should go to production, it is mandatory to have the ability to load and execute modules on the fly. This is useful when you are planning to provide user defined extensions as a mechanism to add new features to the existing software. The .NET Reflection API is a nifty mechanism supported by the Microsoft Corporation to help developers to write code that can be loaded dynamically, after the base software has been written. The platform technologies, such as ASP.net, WCF,EF, and WPF, use reflection extensively:

     public class Test 
     { 
       //---- Only Property this class has  
       public int X { get; set; } 
       //----- This method will be invoked dynamically 
       public void Spit() 
       { 
         Console.WriteLine(" X is " + X); 
       } 
     } 

We will write a simple program that will instantiate the object using the new keyword, and...
