Web services vs API: Top 10+ difference between API and Web Service

Last updated on July 23rd, 2023 at 11:51 pm

A Web API & Web service are ways for two machines to communicate with each other over a network. They both allow for information to be exchanged between a client and a server.

An API or web service hosted on a machine can receive requests from other devices(such as smartphones, computers, and tablets) over a network and sends back the requested resources, which can be in various formats like XML, JSON, HTML, images, audio files, etc.

Web APIs and web services look similar but have some key differences, so we need to know them before incorporating them into our project.

C# Partial Class And Partial Methods With Examples

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.

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.

C# Hashtable vs Dictionary vs HashSet

Last updated on March 27th, 2023 at 10:31 pm

A Hashtable, Dictionary, and HashSet are all data structures that store and retrieve data based on keys. However, there are some important differences between them.

C# Hashtable with example – How to use and when to use?

In this blog post, we will take a deep dive into C# hashtables, explaining what they are, how they work, and how to use them effectively in our C# code.

We will also cover some common scenarios where hashtables can be particularly useful, as well as some tips and best practices for working with them. By the end of this post, you should have a solid understanding of hashtables and how to leverage their power in your C# projects.

Understanding C# Queue Class With Examples

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.

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

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.

Params Keyword in C# With Examples

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

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.

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

Last updated on December 2nd, 2022 at 09:57 pm

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

Last updated on August 7th, 2023 at 09:30 am

Stored procedures and functions are database objects which contain a set of SQL statements to execute a task. Both are different in many respects.

In this post, We will learn 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.

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

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.

C# Unsafe Code: Why do we need unsafe code in C#?

Unsafe code in C#

In general, the code written in C# is safe code that doesn`t directly access memory using pointers. It also doesn’t allocate raw memory. Instead, managed objects are created.
On the other hand, unsafe code in C# usually refers to a section of code that is not processed by the CLR (Common Language Runtime) and directly access memory using pointers.

Since pointers are complex and might result in memory-related errors like stack overflow, overwritten system memory, etc., extra caution must be taken while handling unsafe code.
By default, pointers are not supported in C#. However, the use of pointer variables is permitted by the unsafe keyword.

C# Events: Top 5 Differences between delegates and events in C#

C# Events: The Events enable a class or object to notify other classes or objects when some interesting thing happens to the object. A class that sends or raises the event is called the publisher, and the classes that receive or handle the event are referred to as subscribers.

There can be multiple subscribers to a single event. Typically, when an action takes place, a publisher raises an event. The subscribers who want to be notified when an action takes place should register or subscribe to handle specific events.

The following diagram shows the event in C#.
