如何在c#中按分数对写入文本文件的数据进行排序

using System;
using System.Collections.Generic;
using System.IO;

// 定义数据结构
struct ScoreData
{
    public float score;
    public string name;
}

class Program
{
    static void Main()
    {
        // 读取文本文件中的数据
        List<ScoreData> dataList = new List<ScoreData>();
        using (StreamReader reader = new StreamReader("data.txt"))
        {
            string line;
            while ((line = reader.ReadLine()) != null)
            {
                // 解析每行数据
                string[] parts = line.Split(',');
                float score = float.Parse(parts[0]);
                string name = parts[1];

                // 创建数据对象并添加到集合中
                ScoreData data = new ScoreData { score = score, name = name };
                dataList.Add(data);
            }
        }

        // 按分数进行排序
        dataList.Sort((a, b) => a.score.CompareTo(b.score));

        // 将排序后的数据写入文本文件
        using (StreamWriter writer = new StreamWriter("sorted_data.txt"))
        {
            foreach (ScoreData data in dataList)
            {
                // 格式化每行数据
                string line = string.Format("{0},{1}", data.score, data.name);
                writer.WriteLine(line);
            }
        }
    }
}
