Delegates

Thursday, January 9th, 2020

You already know from the lesson methods and functions and parameters that you can create methods that accept a number of parameters of different types. But what if you would want to send a method itself as a parameter to another method?… Read more

Inheritance

Sunday, November 17th, 2019

In the first lesson of the Objects chapter, I was discussing in a broad way about Object Oriented Programming, acronymed OOP, and I was enumerating it’s fundamental principles: encapsulation, inheritance, abstraction and polymorphism. In this lesson, I will explain inheritance at large, and how class hierarchies improve code readability and reusability.… Read more

Other Data Structures

Saturday, June 16th, 2018

Surprisingly, you will notice that we have already used these data structures before, without knowing they were data structures: the class and the structure. Whenever we instantiate one of these, we are actually using it as a data structure (more or less).… Read more

Enumerations

Sunday, July 16th, 2017

Enumerations are structures which resemble classes but differ from them in that in the enum body we can declare only constants. A variety of logically connected constants can be linked by means of language. These language constructs are the so-called enumerated types.… Read more

Structures

Saturday, June 24th, 2017

In C# and .NET framework, there are two implementations of the concept of “class”, from the OOP point of view: classes and structures.

While we already know that classes are defined using the class keyword, structures are defined using the keyword struct.… Read more

Generic classes

Sunday, June 18th, 2017

Generic classes, also known as generic data types or simply generics, are classes of unknown type until they are instantiated to some specific type.

Because this concept is a bit harder to explain, I will first exemplify a specific case that will help you better understand it.… Read more

Nested classes

Friday, June 9th, 2017

C# offers nested classes, which just like all the other nested programming concepts, implies a construct (class) defined inside the body of another construct (class). The class defined this way is called “inner class”, while the one which contains it, is called “outer class”.… Read more

Instantiation

Wednesday, April 26th, 2017

I have explained a few times already that when we are dealing with objects, most of the times we are not working with the original class itself – the blueprint, but we are actually create copies of it called instances.… Read more

Constructors

Tuesday, April 25th, 2017

In object-oriented programming, when creating objects from given classes, it is sometimes necessary to call some special methods of those classes, known as a constructors.

Constructor of a class is a pseudo-method, which does not have a return type, has the name of the class and is called using the keyword new.… Read more

Classes

Saturday, April 22nd, 2017

At a definition level, classes are objects defined by the keyword class, followed by an identifier (name) and a body (code block), which contains the codes that define the object and its behavior.

Most of the times, classes can contain only four kind of elements:

  • Fields – member variables of a certain type, defined at class level
  • Properties – a special kind of programming constructs which helps us manipulate the fields, and set the properties of the object
  • Methods – they implement the functionality of the object.
