Question

I am creating a high score top5 list and i have no clue how to sort the data from the text file and write out the top5 with the highest int. Right now i have a program that writes the results to the text file highscore.txt.

I want it to look something like this.

Highscore
1. 500pts
2. 450pts
3. 400pts
4. 350pts
5. 300pts

Answer 1

I would suggest to use a real database instead, for example the free Sql-Server Express.

If you really want to use a text-file, you could use this approach:

IEnumerable<string> top5HighScore = File.ReadLines("highscore.txt")
    .Select(line => int.Parse(line))
    .OrderByDescending(score => score)
    .Take(5)
    .Select((score, index) => string.Format("{0}. {1}pts", index + 1, score));

Now you can for example use a foreach to output the strings.

Note that you need to add using System.Linq;.
