Answer 1

You could just do this:

System.IO.File.WriteAllLines("scores.txt",
    textBoxes.Select(tb => (double.Parse(tb.Text)).ToString()));

Answer 2

You may try to write to the file before you close it... after the FileStream fs = File.Create("scores.txt"); line of code.

You may also want to use a using for that. Like this:

if ((!File.Exists("scores.txt"))) //Checking if scores.txt exists or not
    {
        using (FileStream fs = File.Create("scores.txt")) //Creates Scores.txt
        {
            // Write to the file here!
        }
    }

Answer 3

using (FileStream fs = File.Open("scores.txt"))
{
    StreamWriter sw = new StreamWriter(fs);
    scoreArray.ForEach(r=>sw.WriteLine(r));
}

Answer 4

You can convert your List to an array then write the array to a textfile

double[] myArray = scoreArray.ToArray();
File.WriteAllLines("scores.txt",
  Array.ConvertAll(myArray, x => x.ToString()));
