Modifiers
Visual Studio .NET 2003
Modifiers are used to modify declarations of types and type members. This section introduces the C# modifiers:
| Modifier | Purpose |
|---|---|
| Access Modifiers | Specify the declared accessibility of types and type members. |
| abstract | Indicate that a class is intended only to be a base class of other classes. |
| const | Specify that the value of the field or the local variable cannot be modified. |
| event | Declare an event. |
| extern | Indicate that the method is implemented externally. |
| override | Provide a new implementation of a virtual member inherited from a base class. |
| readonly | Declare a field that can only be assigned values as part of the declaration or in a constructor in the same class. |
| sealed | Specify that a class cannot be inherited. |
| static | Declare a member that belongs to the type itself rather than to a specific object. |
| unsafe | Declare an unsafe context. |
| virtual | Declare a method or an accessor whose implementation can be changed by an overriding member in a derived class. |
| volatile | Indicate that a field can be modified in the program by something such as the operating system, the hardware, or a concurrently executing thread. |
