C# 3D Array

C# makes the distinction between jagged and multi-dimensional arrays. Elements of a multi-dimensional array are stored in a contiguous block in memory while elements of a jagged array are not. Java arrays are actually jagged arrays, while C# supports both and allows you to choose which one you want based on the syntax of your code. Note that multi-dimensional arrays are better (in most cases) than jagged arrays.

Using jagged arrays in C# is not as simple as in Java. It’s almost like the way we would implement it in C++. 

int[][] jaggedArray = new int[2][];
jaggedArray[0] = new int[4];
jaggedArray[1] = new int[3]; 

However, multi-dimensional arrays in C# are very simply to use. You can create a 3 dimensional array as follows:

int[,,] array3D = new int[x, y, z]; 

then access its elements at array3D[i][j][k].
Sample Code: 

static void Main(string[] args)
{
    //  Array 3 Dimensions    int x = 4, y = 5, z = 6;

    //  Array Iterators    int i, j, k;

    //  Allocate 3D Array    int[,,] array3D = new int[x, y, z];

    //  Access array elements    for (i = 0; i < x; i++)
    {
        Console.WriteLine(i);

        for (j = 0; j < y; j++)
        {
            Console.WriteLine();

            for (k = 0; k < z; k++)
            {
                array3D[i, j, k] = (i * y * z) + (j * z) + k;
                Console.Write("\t{0}", array3D[i, j, k]);
            }
        }

        Console.WriteLine('\n');
    }
}
