MVC using console program

This short article shows you how to create a MVC program using C# Console project.

MVC is a pattern that does not bound to any programming language. It belongs to neither Java nor .NET.

I modified the sample from http://congeritc.blogspot.in/2013/01/mvc-example-with-c-console-program.html to put all the classes in a single file.

Main Program

class Program

{

    static void Main(string[] args)

    {

        {

            TipCalculatorController t = new TipCalculatorController();

        }

    }

}

 

The Model

class Tip

{

    //private fields

    private double amount;

    private double tipPercent;

    //default constructor

    public Tip()

    {

        Amount = 0;

        TipPercent = 0;

    }

    //overloaded constructor

    public Tip(double amt, double percent)

    {

        Amount = amt;

        TipPercent = percent;

    }

    //public properties

    public double Amount

    {

        get { return amount; }

        set { amount = value; }

    }

    public double TipPercent

    {

        get { return tipPercent; }

        set

        {

            if (value > 1)

            {

                value /= 100;

            }

            tipPercent = value;

        }

    }

    public double CalculateTip()

    {

        //very simplistic tip calculation

        return Amount * TipPercent;

    }

    public double CalculateTotal()

    {

        //simple total calculation

        return CalculateTip() + Amount;

    }

}

 

The View

 

class Display

{

    ///

    //private fields

    private double perc;

    private double amt;

    private double total;

    private double tipAmount;

 

    //constructor

    public Display()

    {

        Percentage = 0;

        TipAmount = 0;

        Amt = 0;

        Total = 0;

        GetValues();

    }

 

    //public properties

    public double TipAmount

    {

        get { return tipAmount; }

        set { tipAmount = value; }

    }

 

 

    public double Total

    {

        get { return total; }

        set { total = value; }

    }

 

 

    public double Percentage

    {

        get { return perc; }

        set { perc = value; }

    }

 

    public double Amt

    {

        get { return amt; }

        set { amt = value; }

    }

 

    private void GetValues()

    {

        Console.WriteLine(“Enter the Amount of the meal”);

        Amt = double.Parse(Console.ReadLine());

 

        Console.WriteLine(“Enter the percent you want to tip”);

        Percentage = double.Parse(Console.ReadLine());

    }

 

    public void ShowTipandTotal()

    {

        Console.WriteLine(“Your tip is {0:C}”, TipAmount);

        Console.WriteLine(“The total will be {0:C}”, Total);

        Console.ReadKey();

    }

}

 

The Controller

 

class TipCalculatorController

{

    private Tip tip;

    private Display display;

 

    public TipCalculatorController()

    {

        display = new Display();

        tip = new Tip(display.Amt, display.Percentage);

        display.TipAmount = tip.CalculateTip();

        display.Total = tip.CalculateTotal();

        display.ShowTipandTotal();

    }

}
