Useful Articles in ASP.NET

1. Public: Any member declared public can be accessed from
outside the class.

2. Private: it allows a class to hide its member variables
and member functions from other class objects and function.
Therefore, the private member of a class is not visible
outside a class. if a member is declared private, only the
functions of that class access the member.

3. Protected: This also allows a class to hide its member
var. and member func. from other class objects and
function, except the child class. it becomes important
while implementing inheritance.

4. Internal: Internal member can be expose to other
function and objects. it can be accessed from any class or
method defined within the application in which the member
is defined

5. Protected Internal: it's similar to Protected access
specifier, it also allows a class to hide its member
variables and member function to be accessed from other
class objects and function, excepts child class, within the
application. used while implementing inheritance.


An access specifier determines how other parts of a program
can access a class member.

Member access is controled by five access specifiers:

1. public,
2. private,
3. protected,
4. internal.
5. protected internal

1. public member can be accessed by any other code in
your program.
2. Main() is declared as public because it will be called
by code outside of its class (the operating system).
3. private member can be accessed only by other members
of its class.
4. A protected member is public within a class hierarchy,
but private outside that hierarchy.
5. A protected member is created by using the protected
access modifier.
6. The internal modifier declares that a member is known
throughout all files in an assembly, but unknown outside
that assembly.
7. The protected internal access level can be given only
to class members.
8. A member declared with protected internal access is
accessible within its own assembly or to derived types.
