Create a Rectangle Class with Length and Width in C#

In this exercise, you will create a new class called Rectangle that represents a rectangle with a given length and width. The class will provide methods to calculate its area and perimeter. Additionally, you will include a method to display the rectangle's details (length, width, area, and perimeter) in a user-friendly format. The class should also allow for modifying the length and width after creation. Finally, you will test the functionality of the Rectangle class in a main program.



Group

Object-Oriented Programming in C#

Objective

1. Create a new class Rectangle with the following attributes:
- Length (double)
- Width (double)
2. Implement a constructor to initialize the rectangle's length and width.
3. Provide a method ToString to return a string representation of the rectangle, including its length, width, area, and perimeter.
4. Implement the GetArea method to calculate the area of the rectangle.
5. Implement the GetPerimeter method to calculate the perimeter of the rectangle.
6. Test the Rectangle class in the main program by creating a few rectangles with different dimensions and displaying their details.

Create a rectangle class that calculates area and perimeter, displays details, and allows modification of length and width.

Example C# Exercise

 Copy C# Code 
using System;

public class Rectangle
{
    // Private fields for the rectangle's dimensions
    private double length;
    private double width;

    // Constructor to initialize the rectangle's length and width
    public Rectangle(double length, double width)
    {
        this.length = length;
        this.width = width;
    }

    // Getter and Setter for Length
    public double Length
    {
        get { return length; }
        set { length = value; }
    }

    // Getter and Setter for Width
    public double Width
    {
        get { return width; }
        set { width = value; }
    }

    // Method to calculate the area of the rectangle
    public double GetArea()
    {
        return length * width; // Area = length * width
    }

    // Method to calculate the perimeter of the rectangle
    public double GetPerimeter()
    {
        return 2 * (length + width); // Perimeter = 2 * (length + width)
    }

    // Method to return the rectangle's details as a string
    public override string ToString()
    {
        return $"Rectangle: Length = {length}, Width = {width}, Area = {GetArea()}, Perimeter = {GetPerimeter()}";
    }
}

public class Program
{
    public static void Main()
    {
        // Create a rectangle with a length of 10 and a width of 5
        Rectangle rectangle1 = new Rectangle(10, 5);

        // Display the details of the first rectangle
        Console.WriteLine(rectangle1.ToString());

        // Create another rectangle with different dimensions
        Rectangle rectangle2 = new Rectangle(15, 7);

        // Display the details of the second rectangle
        Console.WriteLine(rectangle2.ToString());
    }
}

 Output

Rectangle: Length = 10, Width = 5, Area = 50, Perimeter = 30
Rectangle: Length = 15, Width = 7, Area = 105, Perimeter = 44
