MY ARTICLES:
In C#, there are many classes that we can use to represent a group of objects that we may manipulate concurrently using multiple threads. One such class is the ConcurrentBag<T>. In this article, we will learn how to add, access, and remove elements from a...
Often, in our daily routine, we have to deal with secure APIs and use a BearerToken to make HTTP requests. In this article, we are going to learn the correct way to add a BearerToken to an HttpClient request. [sc name="patreon-source-code"...
Return Task by default. Use ValueTask only for a method that is called constantly and usually finishes without ever awaiting anything (a cache lookup that normally hits, a buffered read that normally has data). The reason is what each one costs when it completes...
In this article, we are going to learn about the select tag helper and its various uses. We are going to start with a brief overview of what exactly tag helpers in ASP.NET Core are and then proceed to learn more about the select tag helper. [sc name="github"...
In this article, we'll be looking at ways to update a value stored in a dictionary. A dictionary is a class in C# that allows us to store a collection of key/value pairs in a strongly typed way. [sc name="github"...
In this article, we will learn about default interface methods in C#. So, let's start. Introduction to a Default Interface Method The...
Representing data as strings is an inbuilt feature of the C# language and is a common operation in applications. In this article, we are going to learn how we can use the ToString() method in C# through an example. [sc name="github"...
In this article, we are going to learn about IEnumerable in C#. IEnumerable acts as an abstraction over a collection and allows us to iterate over it without knowing the actual type of the collection. [sc name="github"...
In this article, we are going to learn about BitArray class in C#, how to create an instance of it, and what its properties and methods are. We're also going to learn about the difference between BitArray and bool array. [sc name="github"...
In this article, we are going to learn how to secure passwords with BCrypt.NET to ensure we are up to the industry standards when it comes to security in our .NET environment. [sc name="github"...
When we develop software applications, we may need to create, store and manipulate groups of related objects. In this article, we will discuss the various ways in which we can perform such operations using different collections in .NET. [sc name="github"...
In this article, we will extensively break down the concept of Nullable types in C#. We will discuss the kinds of Nullable types in C#, their characteristics, and how we can use them when building applications. [sc name="github"...
Quartz.NET is a job scheduling library for .NET built from three pieces: a job is the code that runs, a trigger decides when, and a scheduler holds them together and fires them. Everything else is a variation on those three. A trigger can repeat on an interval or...
In this article, we are going to learn about the different ways we can extract Custom Headers from our ASP.NET Core Web API requests. Let's...
In this article, we are going to explore the main concepts behind a linked list. We are going to see how to implement a LinkedList in C# using the LinkedList and LinkedListNode classes and then, how to implement custom linked list classes and methods. [sc...
In this article, we're going to look at some of the ways we can enumerate an Enum in C#. Enums allow us to declare a group of related constant values in a readable way where the underlying data type is usually an integer. [sc name="github"...
When building applications, usually we need to create long-running background tasks, that can be sent to one or more background processes. This is known as a producer/consumer pattern. For these scenarios, we need something more robust than a first-in, first-out...
In this article, we’re going to talk about the difference between the usage of the "is" and equality operators when checking for a null value. [sc name="github" url="https://github.com/CodeMazeBlog/CodeMazeGuides/tree/main/csharp-basic-topics/EqualityVsIsInCSharp"...
Use double for numbers, decimal for money. double is the fast, 64-bit default that every maths library and API expects; decimal is slower and bigger but stores decimal fractions exactly, so amounts add up to the cent. float is the one to skip. It is half the size of...
In a system that stores user credentials, we must pay careful attention to how we store passwords. We must never store passwords in plain text. In this article, we will learn how to use hashing and salting techniques in C# to safely store user passwords. [sc...
