First, this example program written in the C# language demonstrates the use of a three-dimensional array. You can declare and initialize the multidimensional array using the comma syntax.
Example: You can loop over any 3D array using this example code. Adding levels to the for-loop allows it to handle greater dimensions.
Here: We use an int[, ,] type—a three-dimensional integer array reference type.
Tip: When using a multidimensional array, you should specify the dimension lengths on the array creation expression, not the type itself.
Int ArrayArrayAlso: We access elements in a 2D or 3D array using the comma syntax in the array index. We read and write elements using this syntax.
C# program that uses three-dimensional array
using System;
class Program
{
static void Main()
{
// Create a three-dimensional array.
int[, ,] threeDimensional = new int[3, 5, 4];
threeDimensional[0, 0, 0] = 1;
threeDimensional[0, 1, 0] = 2;
threeDimensional[0, 2, 0] = 3;
threeDimensional[0, 3, 0] = 4;
threeDimensional[0, 4, 0] = 5;
threeDimensional[1, 1, 1] = 2;
threeDimensional[2, 2, 2] = 3;
threeDimensional[2, 2, 3] = 4;
// Loop over each dimension's length.
for (int i = 0; i < threeDimensional.GetLength(2); i++)
{
for (int y = 0; y < threeDimensional.GetLength(1); y++)
{
for (int x = 0; x < threeDimensional.GetLength(0); x++)
{
Console.Write(threeDimensional[x, y, i]);
}
Console.WriteLine();
}
Console.WriteLine();
}
}
}

Discussion. Let's consider the uses of multidimensional arrays such as three-dimensional arrays in the C# language. In computer science textbooks, multidimensional arrays are used to model problems that occur in the real world in several dimensions.
For example, two-dimensional arrays model a plane while three-dimensional arrays model a cube or other structure. Structures such as 4D arrays can be used for systems that do not truly require four dimensions but just need more space.
