C# is a simple, modern, general-purpose, object-oriented programming language covers basic C# programming and various advanced concepts related to C#. A More Realistic Example Using Lists. An Example Using Dictionaries concepts are explored and demonstrated using the C# (pronounced C sharp). Here I will explain oops concepts in c# with examples or object oriented programming concepts in c#.net with real time examples or oops or object oriented.
It may sound like something you explain to a child, but I would actually love to hear these answers when I conduct an interview. Encapsulation Say we have a program. It has a few logically different objects which communicate with each other — according to the rules defined in the program. Encapsulation is achieved when each object keeps its state private, inside a class.
Instead, they can only call a list of public functions — called methods. So, the object manages its own state via methods — and no other class can touch it unless explicitly allowed.
If you want to communicate with the object, you should use the methods provided. There are people and there is a cat. They communicate with each other. It may look like this: You can feed the cat. It also has a private method meow. What they can do is defined in the public methods sleep , play and feed. Each of them modifies the internal state somehow and may invoke meow. Thus, the binding between the private state and public methods is made. This is encapsulation. Abstraction Abstraction can be thought of as a natural extension of encapsulation.
In object-oriented design, programs are often extremely large.
And separate objects communicate with each other a lot. So maintaining a large codebase like this for years — with changes along the way — is difficult. Abstraction is a concept aiming to ease this problem. Applying abstraction means that each object should only expose a high-level mechanism for using it.
This mechanism should hide internal implementation details. It should only reveal operations relevant for the other objects. Think — a coffee machine. It does a lot of stuff and makes quirky noises under the hood.
But all you have to do is put in coffee and press a button.
Preferably, this mechanism should be easy to use and should rarely change over time. Another real-life example of abstraction?
Think about how you use your phone: Cell phones are complex. It defines a single variable, called color, which of course is used to tell the color of our car. We declared it as private, which is good practice - accessing variables from the outside should be done using a property.
The Color property is defined in the end of the class, giving access to the color variable. Besides that, our Car class defines a constructor.
It takes a parameter which allows us to initialize Car objects with a color. Since there is only one constructor, Car objects can only be instantiated with a color. The Describe method allows us to get a nice message with the single piece of information that we record about our car.
It simply returns a string with the information we provide. Now, in our main application, we declare a variable of the type Car. In procedural programming, we divide a large set of instructions into procedures. Like functions in C.
Before procedural programming, there was another paradigm and that is monolithic programming. In monolithic programming, everything is written in one large method and all the variables are defined at the topmost location.
But as program size grows managing monolithic and procedural code became difficult so OOP was invented. But before deep diving let me introduce you to the Class and Objects. How would you start?
Top 10 OOPS Concepts In C# .NET With Examples
First, you will have to come up with classes that you will use. So, what is a class then? A class can represent a role such as a student and an employee. A class can also represent an abstract concept. A class has a name, attributes, and behavior.
The class name should represent a concept in the domain you are working on. Example 1: What classes can be there if you intended to develop a manufacturing factory processing system? Here is the class diagram that I come up initially: Analyze this design.
Do you think that Employee class should be part of this set of classes? Because we are modeling the Process and employee should not be the part of it.
It is a verb and cannot be the name of the class. It can be a function of a class.

A class name should be a noun. The idea in my mind is that a suspension system should acquire the data from shock sensor and apply the model to sensors values.
