In this tutorial, you will learn about the concept of classes and objects in C# with the help of examples.

Jan 15, 2025 · Class and Object are the basic concepts of Object-Oriented Programming which revolve around real-life entities. A class is a user-defined blueprint or prototype from which objects are created.

Object Oriented programming organizes code by creating types in the form of classes. These classes contain the code that represents a specific entity. The BankAccount class represents a bank account. The code implements specific operations through methods and properties. In this tutorial, the bank account supports this behavior:

Everything in C# is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects.

Using the is or as operators is the correct way if you know the interface type at compile time and have an instance of the type you are testing. Something that no one else seems to have …

Jun 20, 2015 · It should look like this: public class MyClass: ClassB, InterfaceA{ } ClassB is the base class. InterfaceA is an interface. You can only extend one base class, but you can implement many interfaces.

Nov 20, 2011 · I'm creating an interface where I need a method to reference a class instance of the class that implements the interface. Here is an example: class MyClass : IMyInterface{ public void MyMethod(MyClass a){...} //implemented from the interface. } So how should I implement my interface (without generics) to reference the class that it is ...

Here we are going to understand the class and objects from the C# programming language point of view. But this is also applicable to any object-oriented programming language like java and C++.

May 1, 2024 · Polymorphism is a core concept in object-oriented programming that allows objects of different classes to be treated as objects of a common superclass. It provides a single interface to represent multiple underlying forms (classes) and …

Apr 19, 2025 · To implement from an interface means that the type implements all the methods defined in the interface. For more information, see Interfaces. Classes, structs, and records can be defined with one or more type parameters. Client code supplies the type when it creates an instance of the type.
