Posted By :Srikanth     Posted Date :April 21, 2011    Points :40   Category :C# 
Internal :

It can be accessed by any code in the same assembly but cannot be accessable in another assembly

Protected Internal :

It can be accessed by any code in the same assembly, or by any derived class in another assembly. For a particular project.

If a method is marked as protected internal who can access it?

  
Access is limited to the current assembly or types derived from the containing class (More...)

What is the scope of the access modifier Protected Internal?

  
We can access with in the project and also in the derived project (More...)

Explain about private and internal Access Modifiers?

  
Private:
========
private is an access modifier for type members only. private access is the least accessible and such members are only accessible within the body of the containing type.
Note that nested types within the same containing body can also access those private members.

Internal:
--------
internal is an access modifier for types and type members. internal members are accessible only within file of the same assembly. It is an error to reference an internal type or internal type member outside the assembly within which it was declared.

A common use of internal access is in component-based development because it enables a group of components to interact in a private matter without being exposed to the outer world. For example, a Data Access Layer could have several classes with internal members that are only used by the DAL.

Describe the accessibility modifier protected internal.

  
It's available to derived classes and classes within the same Assembly. (More...)

Explain about public and protected Access Modifiers?

  
Public:

public is an access modifier for types and type members. This is the most permissive access level as there are no restrictions on accessing a public type or type member.

protected:

protected is an access modifier for type members only. A protected member is only accessible within the body of the containing type and from within any classes derived from the containing type (More...)

Define Protected internal.

  
It is available to derived classes and classes within the same Assembly. (More...)

What are class access modifiers ?

  
Access modifiers are keywords used to specify the declared accessibility of a member or a type. This section introduces the four access modifiers:
. Public - Access is not restricted.
. Protected - Access is limited to the containing class or types derived from the containing class.
. Internal - Access is limited to the current assembly.
. Protected inertnal - Access is limited to the current assembly or types derived . from the containing class.
. Private - Access is limited to the containing type.

What is difference between Code access and role based security?

  
Code security is the approach of using permissions and permission sets for a given code to run. The admin, for example, can disable running executables off the Internet or restrict access to corporate database to only few applications.

Role security most of the time involves the code running with the privileges of the current user. This way the code cannot supposedly do more harm than mess up a single user account.

Neither is better. It depends on the nature of the application; both code-based and role-based security could be implemented to an extent.

What are Access Modifiers

  
Public - Access to same assembly or another assembly that references it.

Private - Access to same class or struct.

Protected - Access to same class or struct, or in a class that is derived.

Internal - Access to any code in the same assembly, but not from another assembly.

Protected Internal - Access to any code in the assembly in which it is declared, or from within a derived class in another assembly.

What are the event's access modifiers ?

  
Event's are always public can be used where ever registered. But we can have access modifiers in events.Wecan have events with protected keyword which will be accessible only to inherited classes.We can have private events only for that class. (More...)

What is the use of Internal keyword?

  
Internal keyword is one of the access specifier available in .Net framework , that makes a type visible in a given assembly , for e.g : a single dll can contain multiple modules. (More...)
