How to check whether a matrix is a square matrix in C#

Answer 1

using System;

public class SquareMatrixCheck
{
    public static bool IsSquareMatrix(int[,] matrix) {
        // Get the number of rows and columns
        int rows = matrix.GetLength(0); // Number of rows
        int cols = matrix.GetLength(1); // Number of columns

        // Check if the number of rows equals the number of columns
        return rows == cols; // If equal, it's a square matrix
    }

    public static void Main(string[] args)
    {
        int[,] matrix = {
            { 1, 2, 3 },
            { 4, 5, 6 },
            { 7, 8, 9 }
        };

        if (IsSquareMatrix(matrix)) {
            Console.WriteLine("The matrix is a square matrix.");
        }
        else {
            Console.WriteLine("The matrix is not a square matrix.");
        }
    }
}
