Access is limited to the current assembly or types derived from the containing class

What is the scope of the access modifier Protected Internal?

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

What is the Difference between Internal and Protected Internal Access Modifiers?

  
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. (More...)

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...)

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.
(More...)

How can you access a private method of a class?

  
Use .Net Reflection. Using reflection we can invoke private methods too.

Example:

Car car = new Car();
Type type = car.GetType();
MethodInfo methodInfo = type.GetMethod("ShiftGearUp", BindingFlags.NonPublic | BindingFlags.Instance);
methodInfo.Invoke(car, null);

Pre: Create a class Car with private method "ShiftGearUp" (More...)

Define Protected internal.

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

What is Active Directory? What is the namespace used to access the Microsoft Active Directories? What are ADSI Directories?

  
Active Directory Service Interfaces (ADSI) is a programmatic interface for Microsoft Windows Active Directory. It enables your applications to interact with diverse directories on a network, using a single interface. Visual Studio .NET and the .NET Framework make it easy to add ADSI functionality with the DirectoryEntry and DirectorySearcher components.

Using ADSI, you can create applications that perform common administrative tasks, such as backing up databases, accessing printers, and administering user accounts. (More...)

What is Method overloading?

  
Method overloading occurs when a class contains two methods with the same name, but different signatures. (More...)

What is Method Overriding? How to override a function in C#?

  
Use the override modifier to modify a method, a property, an indexer, or an event. An override method provides a new implementation of a member inherited from a base class. The method overridden by an override declaration is known as the overridden base method. The overridden base method must have the same signature as the override method.
You cannot override a non-virtual or static method. The overridden base method must be virtual, abstract, or override. (More...)

Can we call a base class method without creating instance?

  
Its possible If its a static method.

Its possible by inheriting from that class also.

Its possible from derived classes using base keyword. (More...)
