Console Application : Fibonacci Series.

Create new Console Application Project And Name It As FibonacciSeries.
Now Just Change Your Program.cs With Below Code.

Program.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace FibonacciSeries

{

    class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Series Upto..?");

            int d = int.Parse(Console.ReadLine());

            int a = -1; int b = 1;

            for (int i = 0; i < d; i++)

            {

                int sum = b + a; a = b;

                b = sum;

                Console.WriteLine(b);

            }

            Console.WriteLine("Type and enter to close.");

            Console.ReadLine();

           

        }

    }

}

 

Now Compile And Run The Project.

Enter The Term Upto Which We Want The Fibonacci Series.

My Output's Are As Below.

  All The Best :)
