What are two-dimensional arrays in C#?
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(); } } }
