fibonacci series using for loop in c# program

Hello everyone, I am going to share the code sample for the fibonacci series using c# with console application as given below.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConsoleApplication1

{

    public class FibonacciSeries

    {

        public static int fiboSeries(int n)

        {

            int pre_no = -1;

            int next_no = 1;

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

            {

                int sum = next_no + pre_no;

                pre_no = next_no;

                next_no = sum;

                Console.WriteLine(next_no);

            }

            return next_no;

        }

        static void Main(string[] a)

        {

            int number;

            Console.WriteLine("Enter the number.");

            number = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("\n");

            Console.WriteLine("First " + number + " numbers in the series are equals to ");

            fiboSeries(number);

            Console.Read();

        }

    }

}
