#303 – Accessibility of Class Members

April 16, 2011 9 Comments

Members of a class can have different kinds of accessibility.  An accessibility keyword indicates what source code can access the member.  The different types of accessibility are:

Accessibility Keyword Description
public All code can access the member
private Only other code in the class can access the member
protected Code in this class or any class that inherits from this class can access
internal Code in files in the same assembly (.dll or .exe) can access
protected internal Code in the same assembly or in classes that inherit from this class can access

Accessibility keywords can apply to the following kinds of members of a class: fields, properties, methods, constants, indexers, events, constructors and nested types.  They can apply to both instance and static members.
