In class-based programming, the factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify the exact class of the object that will be created. This is done by creating objects by calling a factory method—either specified in an interface and implemented by child classes, or implemented in a base class and optionally overridden by derived classes—rather than by calling a constructor.

public class Program
{
static void Main()
{
Factory[] objFactories = new Factory[2];
objFactories[0] = new concreteFactoryforEmployee();
objFactories[1] = new concreteFactoryforFounder();
foreach (Factory objFactory in objFactories)
{
DetailsMaster objProduct = objFactory.GetDetails();
objProduct.GetDetails();
}
Console.ReadLine();
}
}

{
public abstract DetailsMaster GetDetails(); //Factory Method Declaration

return new Employee();
