creating a 2 dimensional array in c# code example

Example 1: how to use a 2d array in csharp

int[,] arr = new int[3,3];//declaration of 2D array  
int[,] arr = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 }}//another way to declare
arr[1,2]=20; //access to the array

Example 2: C# public 2d array

// in namespace, above main form declaration

public class Globals
    {
        public static string[,] tableArray;
	}

//... in main or other method

Globals.tableArray = new string[rowLength,colLength];
