如何加载 XML 文件的属性

Question

I want to load the highscore of an XML file and spend the first place in a label. How do I manage to read the first entry and spend its value?

public class Highscore_obj
{
    public string Name { get; set; }
    public int Score { get; set; }
}


class Highscore
{
    public Highscore_obj[] Score_array = new Highscore_obj[4];

    public void LoadXmL(string path)
    {
        XmlDocument XML = new XmlDocument();
        using (Stream s = File.OpenRead(path))
        {
            XML.Load(s);
        }

        Score_array[0].Name = "Alex";
        Score_array[0].Score = 1000;

        Score_array[1].Name = "Chris";
        Score_array[1].Score = 940;

        Score_array[2].Name = "Stefan";
        Score_array[2].Score = 700;

        XmlNodeList Highscores = XML.ChildNodes;

    }

When I start my game the Highscore of Alex must be visible in the label.

Instead of an Array I would rather suggest using a List. Then you can use Linq to query your list and sort by score descending. I would also rather use serialization and deserialization to load and store your List to and from XML.

The code below illustrates this and should get you on the right track.

    internal List<Highscore> Highscores { get; set; }

    public void LoadXmL(string path)
    {
        List<Highscore> highscores = null;

        XmlSerializer ser = new XmlSerializer(typeof(List<Highscore>));

        using (XmlReader reader = XmlReader.Create(path))
        {
            highscores = (List<Highscore>)ser.Deserialize(reader);
        }

        if (highscores == null)
        {
            highscores = new List<Highscore>
            {
                new Highscore{ Name = "Alex", Score = 1000 },
                new Highscore{ Name = "Chris", Score = 940 },
                new Highscore{ Name = "Stefan", Score = 700 },
            };
        }

    }

    public class Highscore
    {
        public string Name { get; set; }
        public int Score { get; set; }
    }

    public Highscore GetHighest()
    {
        return Highscores.OrderByDescending(o => o.Score).First();
    }
