C# Keywords Overview

C# Modifier Keywords

In C#, modifier keywords are used to modify the behavior and accessibility of classes, methods, fields, properties, and other elements in the C# code. Here's a brief description of each modifier keyword:

Keyword	Description
abstract	Indicates that a class or method has no implementation and must be subclassed or overridden.
async	Specifies that a method is asynchronous and can use the "await" keyword to wait for asynchronous operations.
const	Declares a constant value that cannot be changed after initialization.
event	Defines and handles events that allow communication between objects in an event-driven programming model.
extern	Declares a method that is implemented externally, often used with Platform Invoke (P/Invoke) to call unmanaged code.
new	Hides a method with the same name in a base class when creating a method with the same name in a derived class.
override	Indicates that a method, property, or indexer in a derived class overrides a virtual or abstract member in a base class.
partial	Enables the definition of a class or method to be split into multiple files within the same namespace.
readonly	Defines a read-only field or variable whose value can only be set during object initialization or in the constructor.
sealed	Prevents a class from being used as a base class, making it a terminal class that cannot be further derived.
static	Indicates that a member (field, property, method, or nested class) belongs to the type itself, not individual instances.
unsafe	Marks a block of code containing unsafe or unmanaged code, which requires special permissions and bypasses safety features.
virtual	Specifies that a method, property, or indexer in a base class can be overridden in derived classes.
volatile	Indicates that a field can be changed by multiple threads and should not be optimized or cached by the compiler or hardware.
