I am trying to make a Sort of a list that has information from a text file, to fetch the information from the file I use:

string ficheiro = "tvInfo.txt";
List<string> Classificacoes;
var linha = File.ReadAllLines(ficheiro);
Classificacoes = new List<string>();

foreach (var linhas in linha)
{
    Classificacoes.Add(linhas);
}

After fetching the information the list looks like this:

Liverpool;50
Arsenal;10
Benfica;20
PSG;30

I wanted to do the list Sort from the second field. I’m trying to use Linq but I can’t get past here:

Classificacoes.OrderByDescending(c => c);
c# classification

  • It’s pretty simple, you made some code?

    The code I have is just to fill the list with the information from the string file string file = "tvInfo.txt"; List<string> Classifications; var line = File.Readalllines(file); Classifications = new List<string>(); foreach (var lines in line) { Classifications.Add(lines); }

  • So this list just use Linq with the Orderby method that solves

  • That’s what I’ve been trying to do Classificacoes.Orderbydescending(c=>c), but the problem is that I can’t complete the code

  • You need to put this in your question and better organize your code that text still needs to be broken in two parts each row

Come on.

First you need to sort the list from the name or the score?

If it’s from the name, it’s quiet. Just use the Linq Thus:

Classificacoes = Classificacoes.OrderByDescending(c => c).ToList();

That’s because the OrderByDescending return an object to you, so it’s no use you putting it in the void there.


Now, if you need to sort by number, I recommend using a dicionario

Dictionary<string, int>()

where your team’s name is the key, and the number is the score, so you can use the Linq equally, only now, ordering by value:

Classificacoes = Classificacoes.OrderByDescending(key => key.Value).ToList();
