Modifiers (C# Reference)

Modifiers are used to modify declarations of types and type members. This section introduces the C# modifiers.

Modifier	Purpose
Access Modifiers - public - private - internal - protected	Specifies the declared accessibility of types and type members.
abstract	Indicates that a class is intended only to be a base class of other classes.
async	Indicates that the modified method, lambda expression, or anonymous method is asynchronous.
const	Specifies that the value of the field or the local variable cannot be modified.
event	Declares an event.
extern	Indicates that the method is implemented externally.
new	Explicitly hides a member inherited from a base class.
override	Provides a new implementation of a virtual member inherited from a base class.
partial	Defines partial classes, structs and methods throughout the same assembly.
readonly	Declares a field that can only be assigned values as part of the declaration or in a constructor in the same class.
sealed	Specifies that a class cannot be inherited.
static	Declares a member that belongs to the type itself instead of to a specific object.
unsafe	Declares an unsafe context.
virtual	Declares a method or an accessor whose implementation can be changed by an overriding member in a derived class.
volatile	Indicates that a field can be modified in the program by something such as the operating system, the hardware, or a concurrently executing thread.
