Is Abstract Factory Pattern implemented correctly for given scenario.... ???
- by Amit
First thing... I am novice to pattern world, so correct me if wrong anywhere
Scenario:
There are multiple companies providing multiple products of diff size
so there are 3 entities i.e. Companies, Their Product and size of product
I have implement Abstract Pattern on this i.e. so that I will create instance of
IProductFactory interface to get desired product...
Is below implementation of Abstract Factory Pattern correct ??? If not then please correct the approach
+
Also tell me if any other pattern can be used for such scenario
Thanks in advance...

IProductFactory prodFactory = new ProductFactory();
IPhilips philipsObj = prodFactory.GetPhilipsProduct();
MessageBox.Show(philipsObj.CreateProducts(Product.DVD, ProductSize.FortyTwoInch));
or
//ISony sonyObj = prodFactory.GetSonyProduct();
//MessageBox.Show(sonyObj.CreateProducts(Product.DVD, ProductSize.FortyTwoInch));
