For more Overriding in C# is the re-implementation of a base class method in a derived class. In this, the base class method is overridden in child class. The derived class Method overriding is one of the ways by which C# achieve Run Time Polymorphism(Dynamic Polymorphism). The method that is overridden by an override declaration is C# Override Method Use the override keyword on virtual base methods to specify which methods are called. Override.

Of. override means that it will change the implementation of a previously defined method with the same name and parameters void means that it returns nothing.

In C#, overriding occurs within the base class and the derived class. In C#, overloading occurs within the same class.

In this article I will explain all of these keywords and the contexts in which they are used in the C# programming with the help of adequate examples and code snippet explanations for the same In C# there are two mechanisms for redefining or providing the new implementation of a method of parent class by its child class and these two mechanisms are known as Method overriding and Method hiding. Now on the basis of how method re-implementation is done we can distinguish between both of them Unfortunately it's not possible to override ToString () on a enumeration. Instead, you need to provide a helper method to do this: With C# 3.0 you could use an extension method. /// Extension method for the enum MyColor. This method overrides the method ToString of After overriding the abstract method is in the non-Abstract class. We can derive this class in another class, and again we can override the same abstract method with it. Syntax: public abstract void geek(); // the method 'geek()' is abstract. Abstract Class: This is the way to achieve the abstraction in C#. An Abstract class is never intended.
