My First Function ! - now working!!!

using System;

namespace MyFirstFunction

    class MyFirstFunctionTrynumber4

        static void Main(string[] args)
        {

            string enteredNumberText = Console.ReadLine();
            int enteredNumber = 0; //Initialize a variable to store the first number.

            if (!int.TryParse(enteredNumberText, out enteredNumber)) //This will convert the number the string to a number or if this is not possible the error message will display
            // In English this would be: If the result that is returned from the TryParse function is not an integer then print this error message.
            {
                Console.ForegroundColor = ConsoleColor.Red;

            // We get the second Integer
            //Note -> the fact that I cut and pasted this then changed the integer names really strikes me a bad coding, my suspicion is that this would be easier to do with a function - something to work on later
