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 26, 2022December 26, 2022

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.

Params Keyword in C# With Examples

December 17, 2022

The params keyword in C# is used to specify a method parameter that can take a variable number of arguments. Generally, params work as a single-dimensional array of objects.

C# params are useful when you declare a method and don’t know how many arguments will be passed as parameters.

C# Stack Class With Push And Pop Examples

December 29, 2022December 11, 2022

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 Tuple in C#?

December 10, 2022December 9, 2022

A tuple in C# is a data structure that allows us to store elements of different data types. It was first introduced with .NET Framework 4.0 and allowed a maximum of 8 elements to be stored. Any attempt to store more than eight elements will result in a compiler error.

Syntax:

Tuple<T1, T2, T3, T4, T5, T6, T7, TRest>

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.

What Is Node.js and Why Should You Use It?

What Is Node.js?

Node.js is an open-source, cross-platform runtime environment and library for executing JavaScript code outside of a browser. It uses an event-driven, asynchronous, non-blocking I/O architecture, making it lightweight and efficient for data-intensive real-time applications running across distributed devices.

Node.js is neither a framework nor a programming language but a runtime environment. It was written and introduced by Ryan Dahl in 2009.
Node.js was built on top of chrome V8 JavaScript Engine that is written in C++ language. All the JavaScript code is executed by the V8 JavaScript engine; which converts the code into Assembly code, which is then converted into machine code. Machine code is something that a computer processor understands.

Top 10 Differences between Stored Procedure and Function in SQL Server

February 18, 2023October 27, 2022

Last updated on February 18th, 2023 at 02:27 pm

Stored procedures and functions are database objects that contain a set of SQL statements used to execute a task. Both are different in many respects. This post will look at the differences between stored procedures and functions.

Before diving into the differences, it is important to understand the fundamental concepts such as stored procedures, functions, advantages, basic syntax, etc. Let’s start our discussion with an overview.

C# Dynamic Type: Var vs dynamic keywords in C#

October 19, 2022October 19, 2022

The dynamic keyword is used to define dynamic types. Dynamic type is used to avoid compile-time type checking. The compiler does not type-check dynamic type variables at compile time, instead, the compiler check the type at the run time. If the syntax of the statement is invalid, an error will be thrown at runtime.

Dynamic types are similar to object types, despite the fact that type checking for object type variables occurs at compile time rather than at runtime for dynamic type variables.
