Sorting 2 arrays at the same time

Question

I have 2 arrays that i want that i want to sort, but keep the the elements aligned correctly. for instance button1 at element[x] stays with textbox1 at element[x]. theres probably another structure i could use but i can't figure it out.

String[] Teams = { 
    textBox1.Text, textBox2.Text, textBox3.Text, 
    textBox4.Text, textBox5.Text, textBox6.Text, 
    textBox7.Text, textBox8.Text, textBox9.Text 
};
int[] Scores = { 
    Convert.ToInt32(button1.Text), Convert.ToInt32(button2.Text), Convert.ToInt32(button3.Text), 
    Convert.ToInt32(button4.Text), Convert.ToInt32(button5.Text), Convert.ToInt32(button6.Text),
    Convert.ToInt32(button7.Text), Convert.ToInt32(button8.Text), Convert.ToInt32(button9.Text)
};

The first way that comes to mind is to create a data structure for the pairs of data, put those into an array then sort that array by the desired data. You didn't actually specify which data you are wanting to sort on so I will assume it's the textBoxN.Text values.

struct DataInfo {
    public string Name,
    public string Value
}

var data = new List<DataInfo>();
for(var x = 1; x < 10; x++) {
    var textBox = this.Find("textBox" + x);
    var button = this.Find("button" + x); // find the controls somehow

    data.Add(new DataInfo { Name = Convert.ToInt32(button.Text), Value = textBox.Text };
}

data.Sort((left, right) => left.Value.CompareTo(right.Value));

There are actually a couple of ways to sort but the easiest is to pass a lambda into the Sort method on List and just do your sort logic right in there.

I hope this helps, good luck.

Hope the codes below help you. Please let me know if it is working as per your intention. Thanks

            String[] Teams = { 
               "TeamC", "TeamB", "TeamA"
            };

            int[] Scores = { 
                0, 1, 2
            };

            var sortedTest = Teams
                .Select((x, i) => new KeyValuePair<string, int>(x.ToString(), i))
                .OrderBy(x => x.Key)
                .ToList();

            String[] TeamsSorted = sortedTest.Select(x => x.Key).ToArray();
            List<int> idx = sortedTest.Select(x => x.Value).ToList();

            List<int> sortedScores = new List<int>();
            for (int i = 0; i < idx.Count; i++)
            {
                sortedScores.Add(Scores[idx[i]]);
            }

            Console.WriteLine("Sorted Teams: ");
            TeamsSorted.ToList().ForEach((m) => Console.WriteLine(m));

            Console.WriteLine("Sorted Scores: ");
            sortedScores.ToList().ForEach((m) => Console.WriteLine(m));

With Linq:

var sortedByTeam = Teams
    .Zip(Scores, (t, s) => new { Team = t, Score = s })
    .OrderBy(x => x.Team).ToList();
