A 2-dimensional array is a list of one-dimensional arrays.
Two-dimensional arrays may be initialized by specifying bracketed values for each row.
int [,] a = new int [2,2] {
{0, 1} ,
{4, 5}
};The following is an example showing how to work with two-dimensional arrays in C# −
using System;
namespace ArrayApplication {
class MyArray {
static void Main(string[] args) {
/* an array with 3 rows and 2 columns*/
int[,] a = new int[3, 2] {{0,0}, {1,2}, {2,4} };
int i, j;
/* output each array element's value */
for (i = 0; i < 3; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0},{1}] = {2}", i, j, a[i,j]);
}
}
Console.ReadKey();
}
}
}
