What is Access Modifier?

Objects in .NET are created from a class, struct, etc.  These definitions, as well as the properties, methods, or events within them, use an access modifer that determines who can access it.  A class or structure outside of the current class definition or even the in different projects have different access rights depending on the type of accessor used.  Take a look at the accessors below:

Access modifiers determine the extent to which a variable or method can be accessed from another class or object

The following five accessibility levels can be specified using the access modifiers

    * Private
    * Protected
    * Internal
    * Protected internal
    * Public 


This makes the member visible globally

Eg. class Gremlin { public Gremlin spawn() { return new Gremlin(); } }



This makes the member visible to the current class and to child classes.  Protected members are only accessible in the same class or through inherited classes.

Eg. class ParentClass { protected int valueA; }
class ChildClass { public void doSomething() { valueA = 3; } }



This makes the member visible only to the current class.

Eg. class MyCollection { private int lastIndex; }


internal / Friend

This makes the member visible within the same assembly.

Eg. internal class ProprietaryStuff { }


protected internal / Protected Friend

A combination of protected and internal.  This makes the member visible within the same assembly and also makes the member visible to an inheriting class. An inheriting class does not need to be in the same assembly to access the member.

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
