Understanding the Difference between == and Equals() Method in C#

February 1, 2023

In this post, we will be discussing a common confusion among C# developers: the difference between == and equals in C#. Whether you are a beginner or an experienced developer, understanding the difference between these two operators is crucial for writing efficient and accurate code.

In C#, the equality operator ‘==’ evaluates the equality of two operands, while the Object.Equals() method determines if two object instances are equal or not.

In this post, we will cover the purpose, usage, speed, and flexibility of ‘==’ and ‘.Equals()’, as well as some frequently asked questions. So, let’s get started!

Is vs As operator in C#: Understanding the differences between is and as operator in C#

is vs as operator in c#:

In C#, the IS and AS operators are essential keywords used to determine the type of an object during runtime.
The IS operator checks the type of an object and returns a boolean value, which is true if the object is of the same type and false if not. On the other hand, the AS operator not only checks the type of an object but also performs a type conversion if the object is compatible with the given type.

SOLID Design Principles in C#: A Complete Example

September 1, 2023January 19, 2023

Last updated on September 1st, 2023 at 07:53 pm

SOLID is a set of five design principles introduced by Robert C. Martin in 2000 to make code more maintainable, flexible, and scalable.

In this article, we will learn about five important SOLID principles and how they can be used with C# programming. We’ll also see practical examples to understand how to apply these principles in real-world situations.

SOLID Design Principles

SOLID is a widely recognized acronym that represents a set of five fundamental design principles in software development: the Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle.

C# dispose vs finalize – Understanding the difference between dispose and finalize in C#

September 14, 2024January 9, 2023

Last updated on September 14th, 2024 at 01:14 am

The Dispose() and Finalize() are important methods for releasing resources in C#. We use these methods to clean up resources that are no longer needed, such as database connections and files. However, there are significant differences between the “dispose” and “finalize” methods in C#.

The IDisposable interface defines the Dispose() method, while the Object class defines the Finalize() method.
Users can explicitly call the Dispose() method, whereas the Finalize() method is automatically called by the garbage collector (GC) before an object is destroyed.

C# Partial Class And Partial Methods With Examples

January 3, 2023

C# Partial classes and partial methods will allow you to split the implementation of a class or a method across multiple files. This can be useful when working with automatically generated code, as it allows you to make changes to the generated code without losing them when the code is regenerated.

The partial keyword allows you to split the definition of a class, struct, interface, or method into multiple source(.cs) files. Each file contains a part of the definition, and all the parts are combined when the application is compiled.

This article will provide an overview of partial classes and partial methods in C#, including how and why they are implemented.

CSharp-Struct — C# Struct

A C# Struct is a value type that represents a lightweight object. Unlike classes, which are stored on the heap, a struct is stored on the stack, making it more memory-efficient and faster to create and use.

Struct is a perfect choice for creating small, lightweight objects that hold value-type data and do not require inheritance.

Understanding C# Queue Class With Examples

January 1, 2023December 29, 2022

Last updated on January 1st, 2023 at 09:05 am

C# Queue is a linear data structure that follows the First-In-First-Out (FIFO) principle. In other words, the first element added to the queue will be the first one to be removed. This makes queues useful for storing data that needs to be processed in a specific order. The queue is the opposite of the Stack<T> collection.

In C#, the Queue class is a generic collection that implements the IEnumerable interface and provides a variety of methods for adding, accessing, and removing elements in the queue.

A static class is a class that cannot be instantiated and contains only static data members. It is a collection of utility or helper methods that can be called directly by the class name itself without creating an instance of the class.

C# Polymorphism: Different types of polymorphism in C# with examples

December 1, 2023December 26, 2022

Last updated on December 1st, 2023 at 04:36 pm

Polymorphism is a Greek word that means “many-shaped” or multiple forms of an object. You can use polymorphism in case you want to have multiple forms of one or more methods of a class with the same name.

Polymorphism is one of the main key concepts of object-oriented programming after encapsulation and inheritance.

In this article, we are going to learn about the different types of polymorphism in C#, how they work, how to implement them, and how to use polymorphism in our program code.

C# Stack Class With Push And Pop Examples

December 29, 2022December 11, 2022

Last updated on December 29th, 2022 at 01:10 am

Stack in C# represents a last-in, first-out (LIFO) collection of objects. It is useful when you need last-in, first-out access to elements. Adding an element to the stack is called a push operation, and removing an element from the stack is called a pop operation.

A Stack is a collection that can be both generic and non-generic. The generic stack is defined in the System.Collections.Generic namespace. A non-generic stack, on the other hand, is defined under System.Collections namespace. In this post, we will discuss a non-generic type stack.

C# Tuple: How to work with a Tuples in C#?

Last updated on July 25th, 2023 at 12:43 pm

A Tuple<T> is a data structure that allows you to combine multiple elements of different data types into a single object.
It was first introduced with .NET Framework 4.0 and allowed a maximum of eight elements to be stored. Attempting to store more than eight elements will result in a compiler error.

This article will explore how to work with C# Tuples and demonstrate their usage with simple code examples.

C# Nullable types: How do you work with nullable types in C#?

December 5, 2022December 4, 2022

As you know, a value type variable cannot be assigned a null value. For example, if you try to assign a null value to the value type int i = null it will give you a compile-time error.
In this post, you will learn about the C# Nullable Types with the help of multiple examples.
