C# 我想在文本文件中获得一个特定的行以显示在文本框中

我有一个.txt文件，其中包含多个相似项的数据，例如：

Line 1 has - Name: Tom

Line 2 has - Score 1: 10

Line 3 has - Score 2: 5

Line 4 has - Score 3: 5

Line 5 has - Score 4: 7

Line 6 has - Score 5: 10

Line 7 has - Total Score: 37

Line 8 has - Name: Ben

Line 9 has - Score 1: 5

Line 10 has - Score 2: 10

Line 11 has - Score 3: 10

Line 12 has - Score 4: 0

Line 13 has - Score 5: 5

Line 14 has - Total Score: 30

我试图做的是从.txt文件中选择行1、（

名称：Tom

）和行7（

总分：37

）和行8和行14。有没有办法在.txt文件中选择这些特定行，以便在文本框中显示它们

---

我想要的结果是能够将所选的行放入文本框中。任何帮助/建议都将不胜感激。

我将创建一个类来存储名称和分数。这允许您用分数信息填写列表

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

        public override string ToString()
        {
            return $"{Name,-15}: {Score,4}";
        }
    }

您可以枚举行并查看行是否以特定字符串开头

const string path = @"C:\Users\Me\Documents\TheFile.txt";

var players = new List<Player>();
Player currentPlayer = null;
foreach (string line in File.ReadLines(path)) {
    if (line.StartsWith("Name:")) {
        // We have a new person. Create a `Player` object and add it to the list.
        currentPlayer = new Player { Name = line.Substring(6) };
        players.Add(currentPlayer);
    } else if (line.StartsWith("Total Score:") &&
        Int32.TryParse(line.Substring(13), out int score)) {

        // We have a score number. Convert it to `int` and assign it to the current player.
        currentPlayer.Score = score;
    }
}

将数据解析为类。您可以获得姓名和分数：

using System.Linq;

using System.IO;

    class Program
    {
        const string FILENAME = @"c:\temp\test.txt";
        static void Main(string[] args)
        {
            StreamReader reader = new StreamReader(FILENAME);
            string line = "";
            Player newPlayer = null;
            while ((line = reader.ReadLine()) != null)
            {
                line = line.Trim();
                if (line.Length > 0)
                {
                    string[] splitLine = line.Split(new char[] { ':' }).ToArray();

                    if (line.StartsWith("Name"))
                    {
                        newPlayer = new Player();
                        Player.players.Add(newPlayer);

                        newPlayer.name = splitLine[1].Trim();
                    }
                    else
                    {
                        if (line.StartsWith("Score"))
                        {
                            if (newPlayer.scores == null) newPlayer.scores = new List<int>();
                            newPlayer.scores.Add(int.Parse(splitLine[1]));

                        }
                    }
                }
            }

            string[] playersNames = Player.players.Select(x => x.name).ToArray();

            Console.WriteLine(string.Join(" , ", playersNames));
            Console.ReadLine();
        }
    }
    public class Player
    {
        public static List<Player> players = new List<Player>();

        public string name { get; set; }
        public List<int> scores { get; set; }

    }
}

就我个人而言，我只需使用

StreamReader进行循环，检查当前正在读取的行是否包含“Name”或“Total”，并将它们存储到流的末尾。

                    {

                        {
