SOME SIMPLE SOURCE CODES THAT I DEVELOPED IN C#.NET AFTER REFERRING FEW BOOKS FEEL FREE TO POINT OUT ERRORS IF ANY

SOURCE CODE #1
using System;
class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello C#");
        }
    }

OUTPUT OF SOURCE CODE #1

SOURCE CODE #2:

using System;

namespace ConsoleApplication2

{

    public class Fraction

    {

        public Fraction(int numerator, int denominator)

        {

            this.numerator = numerator;

            this.denominator = denominator;

        }

        public void Add(Fraction rhs)   

        {

            if(rhs.denominator != this.denominator)

            {

                throw new ArgumentException("Denominators must match");

            }

            //return new Fraction(this.numerator+rhs.numerator, this.denominator);

            Console.WriteLine("The sum of the two fractions is " + (this.numerator + rhs.numerator) + " / " + this.denominator);

        }

        public override string ToString()

        {

            return numerator + "/" + denominator;

        }

        private int numerator;

        private int denominator;

        public static void Main (String []args)

        {

            Fraction frac = new Fraction(2,3);

            Fraction frac1 = new Fraction(4,3);

            frac1.Add(frac);

        }

    }

}
