Cannot convert from 'SoccerStats.GameResult' to 'SoccerStats.GameResult[]

Getting an error when I am adding the value of gameResult into the soccerResults list. I watched the video and it looks like my program looks just like hers, but I am getting this error, while hers builds. Can someone please help me see what I am overlooking?

using System;
using System.Collections.Generic;
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, "SoccerGamesResults.csv");
            var fileContents = ReadSoccerResults(fileName);

        }

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

        public static List<GameResult[]> ReadSoccerResults(string fileName)
        {
            var soccerResults = new List<GameResult[]>();
            using (var reader = new StreamReader(fileName))
            {
                string line = "";
                reader.ReadLine();
                while((line = reader.ReadLine()) != null)
                {
                    var gameResult = new GameResult();
                    string[] values = line.Split(',');
                    //gameResult.GameDate = DateTime.Parse(values[0]);
                    DateTime gameDate;
                    if(DateTime.TryParse(values[0], out gameDate))
                    {
                        gameResult.GameDate = gameDate;
                    }
                    gameResult.TeamName = values[1];
                    HomeOrAway homeOrAway;
                    if(Enum.TryParse(values[2], out homeOrAway))
                    {
                        gameResult.HomeOrAway = homeOrAway;
                    }
                    soccerResults.Add(gameResult);
                }
            }
            return soccerResults;
        }
    }
}

It seems like in ReadSoccerResults(string fileName) youre initializing soccerResults to a list of GameResults array and returning that. If i recalled that lesson correctly you just want a list of GameResults. When you add gameResult to soccerResults, its expecting an array of the GameResult object or GameResult[], but youre only passing in a single GameResult object. which is what that error is all about.

I would remove the array brackets [] from the initialization and the return type. And that should fix it.
