Hi Gantasala,

Please check below code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace MatrixArray
{
class Program
{
static void Main(string[] args)
{
int r, c;
Console.WriteLine("enter number of rows");
r = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter number of columns");
c = Convert.ToInt32(Console.ReadLine());
int[,] mularr = new int[r, c];
Console.WriteLine("enter array data");
for (int i = 0; i < r; i++)
{
for (int j = 0; j < c; j++)
{
mularr[i, j] = Convert.ToInt32(Console.ReadLine());
}
}
Console.WriteLine("this is the matrix");
for (int i = 0; i < r; i++)
{
for (int j = 0; j < c; j++)
{
Console.Write(mularr[i, j] + "\t");
}
Console.WriteLine();
}
Console.WriteLine("diagonal values of matrix");
for (int i = 0; i < r; i++)
{
for (int j = 0; j < c; j++)
{
if(i == j)
Console.Write(mularr[i, j] + "\t");
}
Console.WriteLine();
}
Console.ReadLine();
}

Hi,
try this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 } };

var rowCount = arr.GetLength(0);
var colCount = arr.GetLength(1);
for (int row = 0; row < rowCount; row++)
{
for (int col = 0; col < colCount; col++)
if (row == col)
Console.Write(String.Format("{0}\t", arr[row, col]));
Console.WriteLine();
}

Console.ReadKey();

}
}
}
