Question

我想将每一行存储在不同的数组中。下面是我尝试的代码。但它不起作用，它只会分割最后一行并将值存储在“ valueperline”数组中

前11行是源文本。控制台的文件和屏幕截图

using System;
using System.Collections.Generic;
using System.IO;
namespace BBS_optimize
{ 

    class Program
    {
        static void Main()
        {
            int i = 0; int j = 0; int k =0; string[] valueperline = new string[0]; string[] lines = new string [0];
           lines = File.ReadAllLines("Table1.txt");
            for (i = 0; i < lines.Length; i++)
            {
                Console.WriteLine(lines[i]);
            }
            for (j = 0; j<lines.Length; j++)
            { valueperline = lines[j].Split('\t');

            }
            for (k = 0; k < 44; k++)
            { Console.WriteLine(valueperline[k]); 
            }

        }
    }
}

使用数组：

string[,] ParseFromFile (string fileName)
{
    // Assume that your table have 10 cols and 100 rows
    string[,] result = new string[10,100];
    string str = File.ReadAllText (fileName);
    // Split each line to arrays
    string[] yourStringArray = str.Split(new[]{'\r', '\n'},StringSplitOptions.RemoveEmptyEntries);
    for (int i == 0; i < yourStringArray; i++)
    {
        string[] row = yourStringArray[i].Split(new[]{" "},StringSplitOptions.RemoveEmptyEntries);
        result[i] = row;
    }
    return result;
}

使用列表：

List<List<string>> ParseFromFile (string fileName)
{
    // Your list
    List<List<string>> result = new List<List<string>>();
    string str = File.ReadAllText (fileName);
    // Split each line to arrays
    string[] yourStringArray = str.Split(new[]{'\r', '\n'},StringSplitOptions.RemoveEmptyEntries);
    for (int i == 0; i < yourStringArray; i++)
    {
        List<string> row = yourStringArray[i].Split(new[]{" "},StringSplitOptions.RemoveEmptyEntries).ToList();
        result.Add(row);
    }
    return result;
}

下面是一个解决方案：

static void Main(string[] args)
    {
        List<List<string>> lst = new List<List<string>>();
        string[] lines = new string[0];
        lines = File.ReadAllLines("tableX.txt");
        for (int i = 0; i < lines.Length; i++)
        {
            Console.WriteLine(lines[i]);
        }
        for (int j = 0; j < lines.Length; j++)
        {
            var line = lines[j].Split(' ').ToList();
            lst.Add(line);
        }
        foreach (var item in lst)
        {
            for (int k = 0; k < item.Count; k++)
            {
                Console.WriteLine(item[k]);
            }
        }
    }

我想从文本文件中读取一个表并将每一列分配给一个数组
