My SoccerStats code does not compile and build the same way.

My code does not compile the same way as hers does in the video. It looks exactly the same. When I CTRL + F5 to run it, I do not get the double lines that she is getting. I then downloaded the project files and ran that code, and it broke it into double lines. I then copied the code into my project, but I still do not get double lines. Could someone tell me if there is something wrong with my code or my IDE?

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

namespace SoccerStats
{
    class Program
    {
        static void Main(string[] args)
        {
            string currentDirectory = Directory.GetCurrentDirectory();
            DirectoryInfo directory = new DirectoryInfo(currentDirectory);
            var fileName = Path.Combine(directory.FullName, "SoccerGameResults.csv");
            var fileContents = ReadFile(fileName);
            string[] fileLines = fileContents.Split(new char[] { '\r', '\n' });
            foreach (var line in fileLines)
            {
                Console.WriteLine(line);
            }

        }

        public static string ReadFile(string fileName)
        {
            using (var reader = new StreamReader(fileName))
            {
                return reader.ReadToEnd();
            }
        }
    }
}

Are you using a Mac or Linux?

I notice the lines are being split using both carriage return ('\r') and line feed ('\n'). In Windows, both of these are present at the end of the line, which will produce an extra blank line between the content lines.

But on Mac or Linux, the line feed is used alone as the end of line, so the split would not generate the blank lines.

Came here to agree with all of you. It seems that my compiler ignores \r and only acknowledges \n as a carriage return when used in conjunction.

I'm guessing the IDE or something was updated to only use \n because I am using Windows 7 with VS 2015 and I only get \n as well. I had no reason to follow the whole StringSplitOptions part of the video.
