Polymorphism With Real Life Scenario In C#

What is polymorphism-with-real-life-scenario-in-C-Sharp & can you give me real life scenario? I have faced this question during many interviews & seen many time on different forums, people are asking the same. But from very few places we are getting a perfect answer that is easy to understand. So as per my understanding & experience I would like to clear this topic through this article.

In overloading we are keeping two or more than two methods in same class with same name but different parameters. The parameter difference may be in term of no. of parameter or in term of type of parameter or order of parameter. Overloading also called Compile Time Polymorphism / Static Binding / Early Binding because here method execution occur at compile time.

Note: It doesn't depend on return type of method.

So suppose you are working on a maintenance project. And you are working on a class where already parameterised constructors has defined & you need to pass some parameter. So what you will do, either add required parameter with one constructor or add new one as per your requirement. So you should not add the required parameter with one constructor because this may disturb your other class dependency structure. So what you will do create a new constructor with required parameter. That new constructor is nothing but constructor overloading. Overriding also called Runtime Time Polymorphism / Dynamic Binding / Late Binding because here method execution happen at run time.
