A sealed class is a class that cannot be inherited by any class but can be instantiated. A sealed class can’t have any derived classes. A common use for a sealed class is to prevent a class from being accidentally inherited.
The purpose of a sealed class is to show that it is highly specialized and does not need to extend to add new functionality through inheritance. This is because it modifies or overrides its behavior.
Boxing and Unboxing: Boxing is the process of converting a value type into a reference type, and unboxing is the process of converting a reference type back into a value type.
C# Arrays: An Array is used to store multiple values in a single variable, rather than declaring a separate variable for each element. It is a fixed-sized sequential collection of elements of the same type.
The data types of the elements in an array can be int, char, float, string, and so on, and they are stored in a contiguous location.
Comments are used in a program to make a section of code easier to understand. They’re used to make the code more readable and to provide a formal description of the code and how it works. The compiler completely ignores comments, so you may put them wherever in a program and not worry about them breaking it.
In this article, we are going to talk about the use of Generics in C# with multiple examples.
In this post, we’ll look at a simple but difficult interview question in C#: Call By Value vs Call By Reference. This is a question that both fresher and experienced developers are asked in interviews. It’s one of the most frequently asked questions by technical interviewers.
In C#, the key difference between abstraction and encapsulation is that encapsulation wraps data and methods into a single unit called class, whereas abstraction hides implementation details and just shows users the functionality.
This post includes the top 50 C# interview questions and answers for freshers and experienced professionals. This article will assist you in improving your C# knowledge and evaluating your present C# understanding.
In this post, we’ll look over how to use the most common collections in C# such as queue, stack, ArrayList, hashtable, and SortedList. We’ll also look at the methods they provide.
Collections in C# are a predefined set of classes that are available in the System.Collections namespace for storing multiple items in a single unit. Collections can be used to perform multiple operations on objects such as storing, updating, deleting, retrieving, searching, and sorting.
Collections are used to work with a group of related objects that can dynamically grow or shrink when objects are added or deleted based on our needs.
In this article, I’ll discuss the differences from a practical standpoint, which should help you in deciding between WCF and Web API.
In this post, we’ll discuss some new C# 10 features that will help you to write cleaner, more expressive, and faster code.
C# 10 is supported by .NET 6 and newer framework versions.
You can download Visual Studio 2022, which comes with the .NET 6 SDK.
The following is a list of some of the new features in C# 10.
