How to create a Three Dimensional List in C# ?

Answer

To create a three-dimensional list in C#, you can use nested List structures to represent the multi-dimensional data.

✐ Examples

1 Create and Populate a 3D List

In this example,

We create a List>> structure to represent the three-dimensional list.
We use nested loops to populate the 3D list with integer values.
We print the elements of the 3D list to demonstrate the structure.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<List<List<int>>> threeDList = new List<List<List<int>>>();

        for (int i = 0; i < 3; i++)
        {
            List<List<int>> plane = new List<List<int>>();
            for (int j = 0; j < 2; j++)
            {
                List<int> row = new List<int>();
                for (int k = 0; k < 2; k++)
                {
                    row.Add(i * 4 + j * 2 + k + 1);
                }
                plane.Add(row);
            }
            threeDList.Add(plane);
        }

        foreach (var plane in threeDList)
        {
            foreach (var row in plane)
            {
                foreach (var element in row)
                {
                    Console.Write(element + " ");
                }
                Console.WriteLine();
            }
            Console.WriteLine();
        }
    }
}

Output
