Goal

Create an instance of FileInfo, named file for the path `.\hello-world.txt.
Using an if statement, check to see if the file exists.
If the file does exist, create a new string variable named fileName and assign it the value using the correct Pathmethod, using the FullName property of your FileInfo instance.
Write the fileName variable to the console using WriteLine.

using System.IO;

public class Program
{
    public static void Main()
    {
        File.WriteAllText(@".\hello-world.txt", "Hello World");

        // Your code here
