difference between keyword internal and protected?..

Answer / dotnetasit

The keywords 'internal' and 'protected' are access modifiers.
If any member in a class is qualified with access
modifier 'internal', then it is friend to the current assembly
but not outside of it. This means any member or class(but not
the dervied classes) within the current assembly can access it.

On the other hand, any member qualified with access
modifier 'protected' can be accessed by derived classes only.

I also want to tell about the combined access
modifier 'protected internal'. Any member qualified with
access modifier 'protected internal' is accessible to the
derived classes as well as to any member or class within the
same assembly. So in a way, this combined modifier extends the
scope of 'internal'.

difference between keyword internal and protected?..

Answer / g2

protected :
This tells that the member is accessible to the derived
class and, in case, the class is a partial class then the
member is accessible to all the other partial classes to
this class. As you can access a protected member declared
in a code behind, you can access it in its respective .aspx
page also. If the member is in a class which is further
derived, it (the member) is available to the derived class
also.

internal :
This tells that the member is accessible any where in the
current assembly or the namespace. It never means that it
has larger scope than the protected. There can be derived
class of a class in other namespaces also. Then the member
with 'protected' will be accessible there but not a member
with 'internal' identifier.

'protected internal' or 'internal protected' :
This combination of identifier is a hybrid of both
protected and internal. But it does not enlarge the
accessibility but shrinks the accessibility instead. It
makes the member accessible to the "DERIVED CLASSES WITHIN
THE CURRENT ASSEMBLY OR NAMESPACE".
