How do we access elements from the two-dimensional array in C#?
A 2-dimensional array can be thought of as a table, which has x number of rows and y number of columns.
An element in 2-dimensional array is accessed by using the subscripts. That is, row index and column index of the array.
int x = a[1,1]; Console.WriteLine(x);
Let us see an example that shows how to access elements from two-dimensional array.
Example
using System; namespace Demo { class MyArray { static void Main(string[] args) { /* an array with 5 rows and 2 columns*/ int[,] a = new int[5, 2] {{0,0}, {1,2}, {2,4}, {3,6}, {4,8} }; int i, j; /* output each array element's value */ for (i = 0; i < 5; i++) { for (j = 0; j < 2; j++) { Console.WriteLine("a[{0},{1}] = {2}", i, j, a[i,j]); } } int x = a[1,1]; Console.WriteLine(x); Console.ReadKey(); } } }
Output
a[0,0] = 0 a[0,1] = 0 a[1,0] = 1 a[1,1] = 2 a[2,0] = 2 a[2,1] = 4 a[3,0] = 3 a[3,1] = 6 a[4,0] = 4 a[4,1] = 8 2
