如何更改C#文本文件中的未知数



我正在尝试为我的Discord Server的机器人创建一个"警告系统",在此使用该命令时,它将从文本文件中获取信息,然后将其更新。我可以在某种程度上设想我想逐步发生的事情,但是我对如何从文件中读取内容的内容感到困惑:

鲍勃#5368 3
标记#8459 6
辛迪#1254 2

我只想更改名称背后的数字,我不确定如何基本上找到要寻找的用户,然后将数字设置为" TotalWarn",然后加上(TotalWarn = Warnnum),然后使用新数字更新该用户。

注意:'警告文件'是该代码块之外已经定义的文件路径。

public async Task warn(IGuildUser user, int warnNum, [Remainder] string reason)
    {
        int totalWarn = 0;
        if (user == null)
            await ReplyAsync("Please include a name");
        if (warnNum <= 0)
            await ReplyAsync("The warning level must increase by 1 or more.");
        if (reason == null)
            await ReplyAsync("Please include a reason.");
        string nickName = user.Username;
        //Check for whether text file exists or not.
        if (!File.Exists(warningFile))
        {
            //Create the File
            FileStream fs = File.Create(warningFile);
        }
        //Reads all the text in the file and puts it into an array.
        string[] arr = File.ReadAllLines(warningFile);
        for (int i = 0; i < arr.Length; i++)
        {
            string line = arr[i];
        }

        totalWarn = +warnNum;
        await Context.Channel.SendMessageAsync($"{user.Username}'s warning level has increased by {warnNum} for {reason}.n"
            + $"Your warning level is now {totalWarn}. Please take this time to review the server rules.");
    }

我不是在寻找有人为我完成它,只是一些帮助,因为我完全迷失了自己的方向,并且有关更改文本的信息也不会有帮助。

这是如何使用REGEX从文件中解析一行的方法:

void Main()
{
    string line = "bob#5368 3";
    GuildUser user = new GuildUser( line );
    user.Warnings++;
    user.ToString().Dump();
}
public class GuildUser
{
    public string Name { get; set;}
    public int Id { get; set;}
    public int Warnings { get; set;}
    public GuildUser( string line )
    {
        Match match = Regex.Match( line, @"(.+)?#(d+) (d+)" );
        if ( !match.Success ) throw new Exception( "Couldn't parse line: " + line );
        Name = match.Groups[1].Value;
        Id = int.Parse( match.Groups[2].Value );
        Warnings = int.Parse( match.Groups[3].Value );
    }
    public override string ToString()
    {
        return $"{Name}#{Id} {Warnings}";
    }
}

您可以使用file.ReadAlllines,file.writealllines。

我可能还会使用一些Linq。

我更新以添加" tostring"方法来重写该行。然后,您只需添加警告并获取新的字符串调用ToString()。

另一种方式:

    public static void stuff()
    {       
        string name = "bob";
        string firstNumber = "";
        string secondNumber = "";
        int lineIndex = 0;
        List<string> lines = new List<string>(File.ReadAllLines(@"C:Text.txt"));
        foreach(string line in lines)
        {
            if(line.Contains(name))
            {
                lineIndex = lines.IndexOf(line);
                string[] parts = line.Split('#');
                name = parts[0];
                firstNumber = parts[1].Split(' ')[0];   
                secondNumber = parts[1].Split(' ')[1];
                firstNumber = (Convert.ToInt32(firstNumber) + 1).ToString();
                /*
                 * instert code here for changing the number you want to change
                */
                lines[lineIndex] = name + "#" + firstNumber + " " + secondNumber;
                File.WriteAllLines(@"C:Text.txt",lines.ToArray());
                break;
            }
        }                   
    }
