How to convert a matrix of numbers to a string in C#

Answer 1

using System;
using System.Text;

class Program
{
    static void Main()
    {
        int[,] matrix = {
            {4, 7, 9, 18, 29, 0},
            {1, 9, 18, 99, 4, 3},
            {9, 17, 89, 2, 7, 5},
            {19, 49, 6, 1, 9, 8},
            {29, 4, 7, 9, 18, 6}
        };

        // Convert matrix to string
        string result = MatrixToString(matrix);

        // Output the result
        Console.WriteLine(result);
    }

    static string MatrixToString(int[,] matrix) {
        StringBuilder sb = new StringBuilder();

        for (int i = 0; i < matrix.GetLength(0); i++) { // Iterate rows
            for (int j = 0; j < matrix.GetLength(1); j++) { // Iterate columns
                sb.Append(matrix[i, j]);

                // Add a space between numbers in the same row
                if (j < matrix.GetLength(1) - 1)
                    sb.Append(" ");
            }

            // Add a newline after each row, except the last one
            if (i < matrix.GetLength(0) - 1)
                sb.AppendLine();
        }

        return sb.ToString();
    }
}
