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

October 15, 2022

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#.

What exactly is a sealed class?

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.

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.

Introduction: Comments in C#

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.

Generics in C# allow you to write type-safe, reusable, and efficient code. In this comprehensive guide, you will learn everything you need to know about generics including how to create generic classes, methods, collections, and generic constraints. This article contains valuable information about C# generics that will help both beginners and experienced C# developers enhance their coding abilities.

C# Generics allow you to reuse the same code (class or method) with different data types. It refers to a generalized version of something rather than a specialized version.
