This is straight forward in C#. If you have used TryParse() function then you already know the answer.

using System;

namespace Demo

{

    class Program

    {

        static void Main()

        {

            Console.WriteLine("Please type your input and press Enter key");

            string strInput = Console.ReadLine();

            int result = 0;

            if (int.TryParse(strInput, out result))

            {

                Console.WriteLine("Your input {0} is a number", result);

            }

            else

            {

                Console.WriteLine("Your input {0} is NOT a number", strInput);

            }

        }

    }

}
