Hi Method Overriding in C# is a type of Dynamic Polymorphism in which binding of method call to actual method implementation happens only during runtime. Method overriding in C# is achieved through inheritance. If a class is inherited by a derived class then the derived class can override the base class method. This concept is termed as Method Overriding.

Hi We can change the behaviour of a function. Best example is abstract method.

It is applied every where in the C# language for example take example for windows forms when you create a new form it is inheriting from a class Form which may have some method or properties virtual that you may need to override to change the behavior of the form. For example take a look at following posts: http://www.c-sharpcorner.com/UploadFile/c713c3/polymorphism-with-real-life-scenario-in-C-Sharp/ http://programmers.stackexchange.com/questions/211789/why-we-use-virtual-and-override-keywords-in-c
