从文件中读取2D矩阵到C#中的2D int数组 [英] Read 2D matrix from file to 2D int array in C#

问题描述

我在从文件读取2D文本并将其导入到 int 数组时遇到问题.具体来说，我的文本文件如下所示:

I have problem in reading 2D text from file and import it to an int array. Specifically, my text file looks like below:

2,3,4,5,6

2,3,4,5,6

5,2,3,4,5

5,2,3,4,5

2,4,6,7,4

2,4,6,7,4

2,7,8,5,6

2,7,8,5,6

因此，矩阵中的每个单元格均以逗号分隔，并且每一行都以新行开头.

So each cell in matrix is separated by comma and each new row starts with new line.

我尝试了多种方法使其有效，但我做不到！简而言之，我想在末尾使用 int [] [] 或 int [，] 数组.

I tried many ways to make it works but I can't! Simply, I want an int[][] or int[,] array at the end.

P.S:我可以简单地将 int [] 读取一维矩阵，如下所示:

P.S: I can read 1-D matrix simply to int[] as below:

int[] array= File.ReadAllText(fileppath).Split(',').Select(t => int.Parse(t)).ToArray();

推荐答案

您首先需要将每行的索引添加到第一个维度，然后将行中的每个列"添加到第二个维度.

You first need to add the index of each line to the first dimension and then every 'column 'in the line to the second dimension.

尝试以下代码:

int[][] array = File.ReadAllText(filepath).Split('\n')
                .Select(r => (r.Split(','))
                .Select(c => int.Parse(c)).ToArray()).ToArray();
