Question

我正在尝试获得一个坐标系，调整x和y值将决定输出我的char的位置。例如，如果我的文本文件包含以下内容：

1 2 3

4 5 6

7 8 9

当我输出数组[2,3] =“X”时，我会得到

1 2 3

4 5 6

7 X 9

目前，我的数组只存储txt内容的第一行。我希望它显示文本中的值1到9。我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace ConsoleApp2Test
{

public class Program

{
    public int xLocation;
    public int yLocation;

    public static void Main()
    {
        int counter = 0;
        string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();
        directory += @"/Maps/Level1.txt";
        char[,] array1 = new char[3, 3];

        for (int i = 0; i < array1.GetLength(0); i++)
        {
            for (int j = 0; j< array1.GetLength(1); j++)
            {
                array1[i, j] = (Char)File.ReadAllBytes(directory)[counter];
                Console.Write(array1[i, j]);
                ++counter;
            }               
        }          
    }

}
}

我做错了吗？

好吧，您的文字似乎比文本文件更具特色。您正在迭代3x3 array1的每个元素，但您的文本文件有11个字符（空白也是如此）。

这是一个动态的（但非常天真）approch：

使用ReadAllText而非ReadAllBytes
Split数组由空白符号
遍历每个标志并将其放入地图

来源：

public static void Main()
{
    string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();
    directory = Path.Combine(directory, @"/Maps/Level1.txt"); // Better use Path.Combine for combining paths

    // It is enough to read the text once and not on every iteration
    string fileContent = File.ReadAllText(directory);

    // In your provided sample the blank sign signals a new row in the matrix
    string[] rows = fileContent.Split(' ');

    // Assuming that it is a matrix, which must always be the same width per line
    // NullChecks ...
    int rowLength = rows[0].Length;
    int rowCount = rows.Length;
    char[,] map = new char[rowLength, rowCount];

    for (int i = 0; i < rowCount; i++)
    {
        for(int j = 0; j < rowLength; j++)
        {
            map[i, j] = rows[i][j];
            Console.Write(map[i, j]);
        }
        // We are done with this row, so jump to the next line
        Console.WriteLine();
    }
}

将文本文件的内容存储到char [，]数组中
