How to initialize a rectangular array in C#?
An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type stored at contiguous memory locations.
Multi-dimensional arrays are also called rectangular array. Multidimensional arrays are initialized by specifying bracketed values for each row.
The following array is with 2 rows and each row has 2 columns.
int [,] a = new int [2,2] {
{20, 50} , /* initializers for row indexed by 0 */
{15, 45} , /* initializers for row indexed by 1 */
};Let us see an example −
Example
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
/* an array with 2 rows and 2 columns*/
int [,] a = new int [2,2] {
{20, 50} , /* initializers for row indexed by 0 */
{15, 45} , /* initializers for row indexed by 1 */
};
int i, j;
for (i = 0; i < 2; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0},{1}] = {2}", i, j, a[i,j]);
}
}
Console.ReadKey();
}
}
}
