In C#, the var keyword is used to declare a variable whose type is implicitly determined by the compiler at …
Introduction: In software development, design patterns play an important role in creating reusable and maintainable code. One such pattern is the Chain of Responsibility design pattern, which promotes loose coupling and flexibility in handling requests.
In this article, we will explore the Chain of Responsibility design pattern in the context of C#, providing clear explanations and practical examples to help beginners grasp its concepts effectively.
In C#, we have two useful methods for checking strings: IsNullOrEmpty() and IsNullOrWhiteSpace(). These methods help us determine if a string is empty or null. But there’s a slight difference between them.

If you are working with date and time values in C#, then it’s important to understand the DateTime format in C#. DateTime is a built-in class in C# representing a date and time value. In this article, we will cover everything you need to know about the DateTime format in C#, including different formats and examples.
A leap year is a year that has an extra day added to its calendar, making it 366 days instead of the usual 365 days. For example, this extra day is added to the month of February, which has 29 days in a leap year instead of the usual 28 days.
Sorting is a fundamental problem in computer science. It refers to the process of arranging data in a specific order. One of the most straightforward algorithms used for sorting is the Bubble Sort algorithm.
Here we will learn how to write a program to copy all elements of an array into another array using different programming languages like C#, Python, C, Java, and PHP.
If you are working with data in C#, you might have heard about IEnumerable and IQueryable interfaces. These two interfaces are used in LINQ (Language Integrated Query) to query data from a data source. But what is the difference between IEnumerable and IQueryable? When should we use one over the other?
In this article, we will explore the differences between IEnumerable and IQueryable in C#.
SQL foreign key is a field in a table that points to the primary key of another table. It links two tables together and creates a relationship between them based on the common fields.
