XNA displaying data from text file to array

Question

right now, I'm going to make a scoreboard for my game. the program will displayed data from text file.

in the program, I have arrays of string for player name and score.

this is my streamreader code look like :

 public void ReadHighScores()
    {
        try
        {
            using (StreamReader sr = new StreamReader("highscore.txt"))
            {

                string line;
                while ((line = sr.ReadLine()) != null)
                {
                    string[] parts = line.Split(',');
                    for (int i = 0; i < 5; i++)
                    {
                        highScores.PlayerName[i] = parts[0];
                        highScores.Score[i] = parts[1];
                    }
                }
            }


        }
        catch (FileNotFoundException ex)
        {
            //IntializeHighScores();
            //WriteHighScores();
        }
        catch (Exception ex)
        {
            // Handle unexpected exception
        }
        finally
        {
            // Close the file
        }
    }

and this is how I draw that scoreboard :

        for (int i = 0; i < 5; i++)
        {
            spriteBatch.DrawString(spriteFont, i + 1 + ". " + highScores.PlayerName[i].ToString()
           + "......" + highScores.Score[i].ToString(), new Vector2(350, 150 + 50 * (i)), Color.Red);
         }

when I run the game. the succesfully read the data from text file. but it only displayed last data in the text file.

my text file contain :

 Alpha, 3500
 Beta, 3600
 Gamma, 2200
 Delta, 3400
 Epsilon, 3600

and the program only display the last data in loop like :

Epsilon 3600
Epsilon 3600
Epsilon 3600
Epsilon 3600
Epsilon 3600

what must I do to display all data from the text file, not only the last one ???

You're almost right, but for every line you read from the file, you assign each member of the high scores array with the same data (in the for loop). You need to figure out which line you are on (just have a counter that gets incremented on every loop of the file reading loop) and only update the respective PlayerName and Score.

No, in the while ((line = sr.ReadLine()) != null) loop, take the for loop out, and use a variable to track how many times the while loop has run. Use that to index the array instead.

so I need to add for loop above the while ((line = sr.ReadLine()) != null)...?

hmm, I still not get it. can you give an code example of it...?

Create a variable i at the top of ReadHighScores. Take out the for loop in ReadHighScores. At the end of the while ((line = sr.ReadLine()) != null) loop body, put i++;.
