Access Modifiers

Access Modifiers

It is very important to understand when and where to use access modifiers.

1) private

2) public

3) protected

4) internal

5) protected internal

1) private : It is visible to only the same class .You cannot access the variable from any other class, even by creating an object or by inheriting it to a child class.

eg:

Class Parent

private Var A

2) public : It is visible through out the project and the variable can be accessed from other project.

eg:

Class Parent

public Var A

3) protected : It is visible inside the class. It cannot be accessed directly from other class. It has to be inherited to access it.

eg:

Class Parent

protected Var A

Class Child

Inherits Parent

base.A

4) internal : It is visible all over the project except from other project or applications

eg:

Class Parent

internal Var A

5) protected internal : It is visible all over the project except from other procect or applications. It can be accessed in other project only by inheriting the base class.

eg:

Class App1.Parent

protected internal Var A

Class App2.Child

Inherits Appl1.Parent

base.A

I am sorry for being very short in defining.
