Question

I've seen this one done as a console application, however I need some help setting it up as a windows form app using micrsoft visual c#.

C# project - Create an application named ShapesDemo that creates several objects that descend from an abstract class called GeometricFigure. Each GeometricFigure includes a height, a width, and an area. Provide get and set accessors for each field except area; the area is computed and is read-only. Include an abstract method calledComputeArea() that computes the area of the geometricFigure. Create three additional classes:

a. A Rectangle is a GeometricFigure whose area is determined by multiplying width by height.

b. A Square is a Rectangle in which the width and height are the same. Provide a constructor that accepts both height and width, forcing them to be equal if they are not. Provide a second constructor that accepts just one dimension and uses it for both height and width. The Square class uses the Rectangle’s ComputeArea() method.

c. A Triangle is a GeometricFigure whose area is determined by multiplying the width by half the height.

In the ShapesDemo class, after each object is created, pass it to a method that accepts a GeometricFigure argument in which the figure’s data is displayed.

Please find my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace ShapesDemo
{
    abstract class GeometricFigure
    {
        static void Main(string[] args)
        {
            Rectangle rectangle = new Rectangle(8, 8);
            Square square = new Square(8, 8);
            // DisplayFigureResults(square);
            Triangle triangle = new Triangle();
            //Console.WriteLine("The Area is:", rectangle.ToString());
            Console.WriteLine("The Area is: {0}", rectangle.ComputeArea().ToString());
        }
        public int height;
        public int width;
        //public readonly double area;
        public int heigth
        {
            get { return height; }
            set { height = value; }
        }
        public int Width
        {
            get { return width; }
            set { width = value; }
        }
        // public double area
        // { get { return area; } }
        public abstract double ComputeArea();
        private static void DisplayFigureDetails(GeometricFigure shape)
        { }
    }
    class Rectangle : GeometricFigure
    {
        protected int p;
        protected int p_2;
        //private int p;
        //private int p_2;
        //added
        public Rectangle()
        {
        }
        public Rectangle(int p, int p_2)
        {
            // TODO: Complete member initialization
            this.p = p;
            this.p_2 = p_2;
        }
        public override double ComputeArea()
        {
            //Console.WriteLine("The Area is" + width.ToString(), height.ToString());
            //return width * height;
            return p * p_2;
        }
    }
    class Square : Rectangle
    {
        //private int p;
        //private int p_2;
        public Square(int p, int p_2)
        {
            // TODO: Complete member initialization
            this.p = p;
            this.p_2 = p_2;
        }
        private static void DisplayFigureDetails(GeometricFigure Square) { }
        public void equal(int height, int width)
        {
            if (height.Equals(width))
                Console.WriteLine("{0} for {1} has the same messers " +
                height, width);
        }
    }
    class Triangle : GeometricFigure
    {
        private static void DisplayFigureDetails(GeometricFigure Triangle) { }
        public override double ComputeArea()
        {
            return width * (height / 2);
        }
    }
}
