factory pattern c# real world example

WHY FACTORY:

• Initially an object is created with the “new” operator. That basic mechanism of object creation could result in design problems or added complexity to the design. On each Object creation we must use the new keyword. The Factory helps you to reduce this practice and use the common interface to create an object.

▸What is Factory

▸The Factory Pattern is a Creational Pattern that simplifies object creation. You need not worry about the object creation; you just need to supply an appropriate parameter and factory to provide you a product as needed.

▸Creating objects without exposing the instantiation logic to the client

▸Referring to the newly created objects through a common interface
