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	Specify the declared accessibility of types and type members.
abstract	Indicates that a class is intended only to be a base class of other classes.
const	Specify 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	Hides an inherited member from a base class member.
override	Provides a new implementation of a virtual member inherited from a base class.
partial	Defines partial classes and structs 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 rather than 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.
