Can an abstract class have properties?
An abstract class cannot be instantiated. An abstract class not only contains abstract methods and assessors but also contains non-abstract methods, properties, and indexers. It is not possible to modify an abstract class with the sealed modifier because the two modifiers have opposite meanings.
Can properties in a base class be overridden?
The GetInfo method can be overridden by any derived class that inherits properties from a base class called Users. Generally, whenever the virtual method is invoked, the run-time object will check for an overriding member in the derived class.
Does the base class has its own properties and functionality?
The class which inherits the base class has all members of a base class as well as can also have some additional properties. The Base class members and member functions are inherited to Object of the derived class. A base class is also called parent class or superclass.
What inherits the properties of a base class?
The class which implements the original properties or methods and will be inherited from is called the base class; the class which inherits from the base class is called the derived class. A derived class inherits from a base class.
When would you use an abstract class instead of an interface?
Abstract classes should be used primarily for objects that are closely related, whereas interfaces are best suited for providing a common functionality to unrelated classes. Interfaces are a good choice when we think that the API will not change for a while.
Which is the base class that is accessed?
The base class that is accessed is the base class specified in the class declaration. For example, if you specify class ClassB : ClassA, the members of ClassA are accessed from ClassB, regardless of the base class of ClassA.
How are properties declared in a class block?
Properties are declared in the class block by specifying the access level of the field, followed by the type of the property, followed by the name of the property, and followed by a code block that declares a get-accessor and/or a set accessor.
Which is the base class of the derived class?
The base class that is accessed is the base class specified in the class declaration. For example, if you specify class ClassB : ClassA, the members of ClassA are accessed from ClassB, regardless of the base class of ClassA. In this example, both the base class, Person, and the derived class, Employee, have a method named Getinfo.
This example demonstrates how to access a property in a base class that is hidden by another property that has the same name in a derived class:
