I want to read a 30x30 2-dimensional array containing commas from a text file and assign it to a two-dimensional array. How do I do this in C#?

Content of my text file:

1, 0, 1, 1, 1
1, 1, 0, 1, 0
1, 0, 1, 0, 0
0, 0, 1, 1, 1

It continues like this. It has 30 rows and 30 columns.

StreamReader streamReader = new StreamReader("Path/To/File.txt");
int[,] myMatrix = new int[30, 30];
for (int row = 0; row < 30; row++)
{
    int[] line = streamReader.ReadLine().Split(", ").Select(int.Parse).ToArray();
    for (int col = 0; col < 30; col++)
    {
        myMatrix[row, col] = line[row];
    }
}

  • I applied these code pieces but there is an error: System.FormatException 'input string was not in a correct format.' – user19108367 May 15 '22 at 18:08

  • On what line did you get the error? The code works for me. – John May 16 '22 at 08:15
