Nytro Posted February 13, 2013 Report Posted February 13, 2013 [h=1]Object Oriented Programming in C#.net[/h]Ajay Yadav February 12, 2013OOP’s overview Object-oriented programming is the core ingredient of the .NET framework. OOP is so important that before embarking on the road to .NET, you must understand its basic principles and terminology to write even a simple program. The fundamental idea behind OOP is to combine into a single unit both data and the methods that operate on that data,with such units being called an object. All OOP languages provide mechanisms that help you implement the object-oriented model. They are encapsulation, inheritance, polymorphism and reusability. Let’s take a brief look at these concepts: Encapsulation This mechanism binds together code and the data it manipulates, and keeps both safe from outside interference and misuse. Encapsulation is a protective container that prevents code and data from being accessed by other code defined outside the container. Inheritance Inheritance is the process by which one object acquires the properties of another object. A type derives from a base type, taking all the base type members’ fields and functions. Inheritance is most useful when you need to add functionality to an existing type. For example all .NET classes are inherited from System.Object classes, so a class scans its new functionality as well as the existing Object class functions and properties. Polymorphism Polymorphism is a feature that allows one interface to be used for a general class of action. This concept is often expressed as “one interface, multiple actions.” The specific action is determined by the exact nature of circumstances. Reusability Once a class has been written, created and debugged, it can be distributed to other programmers for use in their own program. This is called reusability or, in .NET terminology, this concept is called a component or DLL. However, in OOP, inheritance provides an important extension to the idea of reusability. A programmer can take an existing class and without modifying it, add more features to it.Articol:http://resources.infosecinstitute.com/object-oriented-programming-in-c-net/ Quote
