Microsoft Visual C#: An Introduction to Object-Oriented Programming, 7th Edition 2017. Programming Exercise #2 page 476.

Please keep it simplified and easy to understand.

Create an application class named PhotoDemo that demonstrates the methods of three related classes for a company that develops photographs. Create a class named Photo that includes fields for width and height in inches and properties for each field. Include a protected price field, and set it to $3.99 for an 8-inch by 10-inch photo, $5.99 for a 10-inch by 12-inch photo, and $9.99 for any other size (because custom cutting is required). The price field requires a get accessor but no set accessor. Also include a ToString() method that returns a string constructed from the return value of the objects GetType() method and the values of the fields. Derive two subclasses MattedPhoto and FramedPhoto. The MattedPhoto class includes a string field to hold a color, and the FramedPhoto class includes two string fields that hold the frames material (such as silver) and style (such as modern). The price for a MattedPhoto increases by $10 over its base cost, and the price for a FramedPhoto increases by $25 over its base cost. Each subclass should include a ToString() method that overrides the parent class version.

The solution NEEDS to include the following:

Photo packageA = new Photo(); packageA.Width = 8; packageA.Height = 10;

MattedPhoto packageB = new MattedPhoto(); packageB.Width = 10; packageB.Height = 12; packageB.Color = "purple";

FramedPhoto packageC = new FramedPhoto(); packageC.Width = 11; packageC.Height = 14; packageC.Material = "silver"; packageC.Style = "modern";

FramedPhoto packageD = new FramedPhoto(); packageD.Width = 8; packageD.Height = 10; packageD.Material = "wood"; packageD.Style = "traditional";

Hint ... Parent Photo price logic (one way to meet the criteria given in the exercise) price = 9.99; if (Width == 8) price = 3.99; if (Width == 10) price = 5.99;

The result should match the screenshot exactly:
