Can you override private virtual methods?

Posted By :Narayanan     Posted Date :February 28, 2013    Points :40   Category :C# 
No, private methods are not accessible outside the class.

You can also find related Interview Question to Can you override private virtual methods?  below: 

Can you override private virtual methods in .NET Framework?

  
No, moreover, you cannot access private methods in inherited classes, have to be protected in the base class to allow any sort of access. (More...)

Expalin one difference between Abstract and virtual methods?

  
Virtual method can be overriden in any of its derived class and abstract method must be overriden in any of the non abstract class. (More...)

Are Java Methods Virtual by Default?

  
Java methods are virtual by default. The virtual methods are the methods of subclasses. They are invoked by a reference of their super class. The methods of the object are invoked when a method is invoked by using the reference to that object, hence they are virtual. (More...)

What is the use of virtual, sealed, override, and abstract?

  
. The use of virtual keyword is to enable or to allow a class to be overridden in the derived class.
. The use of sealed keyword is to prevent the class from overridden i.e. you can't inherit sealed classes.
. The use of override keyword is to override the virtual method in the derived class.
. The use of abstract keyword is to modify the class, method, and property declaration. You cannot directly make calls to an abstract method and you cannot instantiate an abstract class (More...)

What is use of Virtual,sealed,override,abstract keyword?

  
The use of virtual keyword is to enable or to allow a class to be overridden in the derived class.
The use of sealed keyword is to prevent the class from overridden i.e. you can't inherit sealed classes.
The use of override keyword is to override the virtual method in the derived class.
The use of abstract keyword is to modify the class, method, and property declaration. You cannot directly make calls to an abstract method and you cannot instantiate an abstract class. (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...)

What is Private Constructor? and it's use? Can you create instance of a class which has Private Constructor?

  
When a class declares only private instance constructors, it is not possible for classes outside the program to derive from the class or to directly create instances of it. (Except Nested classes)
Make a constructor private if:

1) You want it to be available only to the class itself. For example, you might have a special constructor used only in the implementation of your class' Clone method.

2) You do not want instances of your component to be created. For example, you may have a class containing nothing but Shared utility functions, and no instance data. Creating instances of the class would waste memory. (More...)

What are private assemblies and shared assemblies?

  
A private assembly is used only by a single application, and is stored in that application's install directory (or a subdirectory therein). A shared assembly is one that can be referenced by more than one application. In order to share an assembly, the assembly must be explicitly built for this purpose by giving it a cryptographically strong name (referred to as a shared name). By contrast, a private assembly name need only be unique within the application that uses it.
By making a distinction between private and shared assemblies, we introduce the notion of sharing as an explicit decision. Simply by deploying private assemblies to an application directory, you can guarantee that that application will run only with the bits it was built and deployed with. References to private assemblies will only be resolved locally to the private application directory.
There are several reasons you may elect to build and use shared assemblies, such as the ability to express version policy. The fact that shared assemblies have a cryptographically strong name means that only the author of the assembly has the key to produce a new version of that assembly. Thus, if you make a policy statement that says you want to accept a new version of an assembly, you can have some confidence that version updates will be controlled and verified by the author. Otherwise, you don't have to accept them.
For locally installed applications, a shared assembly is typically explicitly installed into the global assembly cache (a local cache of assemblies maintained by the .NET Framework). Key to the version management features of the .NET Framework is that downloaded code does not affect the execution of locally installed applications. Downloaded code is put in a special download cache and is not globally available on the machine even if some of the downloaded components are built as shared assemblies.
The classes that ship with the .NET Framework are all built as shared assemblies. (More...)

What is web application virtual directory?

  
A virtual directory appears to client browsers as though it were
contained in a Web server's root directory, even though it can physically Reside somewhere else. (More...)
