Access Modifiers

The access modifiers of an item control the visibility (accessibility) of the item to other code. For example, you can call public methods from anywhere, whereas private methods can be called only from other methods within the same type.

Context:

    Classes
    ValueTypes 
    Interfaces
    Delegates and Events 
    Enums

    Fields

    Methods  
    Properties 
    Indexers 
    Iterators

Further Information

By default, all types and members are PUBLIC, with the exception of fields which are PRIVATE.

The modifier affects the visibility of an item as follows:

Modifier:	Item is visible:
PUBLIC	always
PRIVATE	when the calling type is the same as the target type
PROTECTED	when the calling type inherits from the target type.
INTERNAL	when the calling type is in the same assembly as the target
PROTECTED INTERNAL or INTERNAL PROTECTED	when the calling type derives from the target type, or the calling type is in the same assembly as the target

PUBLIC: Indicates that this item may be accessed from any code.
PRIVATE: Indicates that this item may be accessed only from within the containing type.
PROTECTED: Indicates that this item may be accessed only from within the containing type or from a subtype that inherits from the containing type. You cannot specify PROTECTED on an abstract member. PROTECTED restricts access within an inheritance tree. For example, a protected field in a superclass can be accessed from any subclass, but it can't be accessed from a class outside the inheritance tree.
INTERNAL: Indicates that this item may be accessed only from within the current compilation unit.
PROTECTED INTERNAL or INTERNAL PROTECTED: Indicates that this item may be accessed only from within the containing type, from a subtype that inherits from the containing type, or from within the current compilation unit.
