c# fahrenheit and celsius: adding input to answer

I have written some c# code for a small program (fahrenheit to celsius and Vice Versa), but I would like to add the number of the input to the answer.

I would like the result to read/show: 178 degrees fahrenheit is 81 celsius degrees.

Code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace FahrentheitTest
{
    class Program
    {
        static void Main(string[] args)
        {
            //conversion from Fahrenheit to Celsius
            Console.WriteLine("Input temperature value to view Fahrenheit to  Celsius: ");
            int fah = int.Parse(Console.ReadLine());
            Console.WriteLine();

            //conservsion formula from F to C
            int FtoC = ((fah - 32) * 5) / 9;
            Console.WriteLine("Degrees Fahrenheit is {0} Celsius degrees. ", FtoC);
            Console.WriteLine();

            //conversion from Celsius to fahrenheit
            Console.WriteLine("Input temperature value to view Celsius to Fahrenheit: ");
            int cel = int.Parse(Console.ReadLine());
            Console.WriteLine();

            //conversion formula from C to F
            int CtoF = ((cel * 9) /5) + 32;
            Console.WriteLine("Degrees Celsius is {0} degrees Fahrenheit. ", CtoF);
            Console.WriteLine();
        }
    }
}

I would suggest learning how to encapsulate your rules/logic right off the bat.

Your "immediate need" answer is in the ToString implementation.

namespace Weather
{
    using System;

    public class CeliusToFahrentheit
    {

        public int? Celius { get; set; }
        public int? Fahrentheit
        {
            get
            {
                int? returnValue = null;

                if (this.Celius.HasValue)
                {
                    returnValue = ((this.Celius * 9) / 5) + 32;
                }

                return returnValue;
            }
        }

        public override string ToString()
        {
            string returnValue = string.Empty;

            if (this.Celius.HasValue)
            {
                returnValue = string.Format("{0} degrees celsius is {1} fahrenheit degrees.", this.Celius.Value, this.Fahrentheit.Value);
            }
            return returnValue;
        }
    }
}

and calling code

    static void Main(string[] args)
    {

        try
        {

            CeliusToFahrentheit ctf = new CeliusToFahrentheit();
            ctf.Celius = 100;
            Console.WriteLine(ctf.Fahrentheit);
            string mesg = ctf.ToString();
            Console.WriteLine(mesg);

I think you almost got it.

Console.WriteLine("{0} Degrees Fahrenheit is {1} Celsius degrees.", fah, FtoC);

Wouldn't you just also have the input variable into the same Console.WriteLine, but as the first parameter?

You seem to already have figured out how to print a string with one formatting placeholder:

Console.WriteLine("a is equal to {0}.", a);

You can extend it to two by just adding another placeholder and variable like this:

Console.WriteLine("a is equal to {0} and b is equal to {1}.", a, b);

Modify your format string to include two format values, one for the input and one for the result:

Console.WriteLine("{0} Degrees Fahrenheit is {1} Celsius degrees. ", fah, FtoC);

Console.WriteLine("{0} Degrees Celsius is {1} degrees Fahrenheit. ", cel, CtoF);
