C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web apps, desktop apps, mobile apps, games and much more.

The original static method Base.F will be visible again in class inheritted from your class - MoreDerived). The method which is overridden by the override declaration is called the overridden base method. This will be present in the base class. The overridden base method can be either abstract, override or virtual. Fresh implementation called, override method is inherited from this base class. We use different keywords for method overriding. They are, 1. Dec 13, 2018 · Override the Display method using override modifier in DerivedClass. And define another Display method to hide it’s base class version in DerivedClass using new modifier. That means, now we have 2 Display methods in DerivedClass; one is defined using override modifier and another one is defined using new modifier. Sealed Methods in C#. Sealed methods are defined as that the method is a parent class and that method cannot be overridden under child class. When the method is declared virtual in a class any of the child classes can override a method: Example #1. Code: using System; public class Sample_Employee {protected int Emp_id, Emp_age; the F method in B hides the virtual F method inherited from A. Since the new F in B has private access, its scope only includes the class body of B and does not extend to C. Therefore, the declaration of F in C is permitted to override the F inherited from A. 10.7 Properties (extract from "C#, Language Specification", Version 4.0)

When we create the object of derived class it will hide the base class method and will call its own method and this is called method hiding or name hiding in C# inheritance. May 09, 2007 · Method hiding in C# is similar to the function overriding feature in C++. Functions of the base class are available to the derived class. If the derived class is not happy, one of the functions available to it from the base class can define its own version of the same function with the same function signature, just differing in implementation. Method Hiding. Why did the compiler in the second listing generate a warning? Because C# not only supports method overriding, but also method hiding. Simply put, if a method is not overriding the derived method, it is hiding it. A hiding method has to be declared using the new keyword. The correct class definition in the second listing is thus:
