How to add two matrices (matrix) in C#

Answer 1

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int[,] matrix1 = new int[,] { { 1, 1}, { 2, 2}, { 3, 3}, { 4, 4} };
            int[,] matrix2 = new int[,] { { 5, 5 }, { 6, 6 }, { 7, 7 }, { 8, 8 } };
            int[,] sum = new int[,] { { 0, 0 }, { 0, 0 }, { 0, 0 }, { 0, 0 } };


            int rows = matrix1.GetUpperBound(0);
            int cols = matrix1.GetUpperBound(1);

            for (int i = 0; i <= rows; i++)
                for (int j = 0; j <= cols; j++)
                    sum[i, j] = matrix1[i, j] + matrix2[i, j];

            for (int i = 0; i <= rows; i++)
            {
                for (int j = 0; j <= cols; j++)
                    Console.Write("{0, 2} ", sum[i, j]);
                Console.WriteLine();
            }
        }
    }
}
