How to create a Two Dimensional Array in C# - Step by Step Examples



How to create a Two Dimensional Array in C# ?

Answer

To create a Two Dimensional Array in C#, you can declare and initialize a multidimensional array.



✐ Examples

1 Creating a 2D Array of Integers

In this example,

  1. We declare and initialize a 2D array of integers named matrix with dimensions 3x3.
  2. We assign values to the elements of the array.
  3. The outer loop iterates over rows, and the inner loop iterates over columns to fill the array.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[,] matrix = new int[3, 3];
        for (int i = 0; i < 3; i++)
        {
            for (int j = 0; j < 3; j++)
            {
                matrix[i, j] = i + j;
            }
        }
        Console.WriteLine(matrix);
    }
}

Output

System.Int32[,]

2 Creating a 2D Array of Strings

In this example,

  1. We declare and initialize a 2D array of strings named matrix with dimensions 2x2.
  2. We assign values to the elements of the array.
  3. The outer loop iterates over rows, and the inner loop iterates over columns to fill the array.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[,] matrix = new string[2, 2];
        for (int i = 0; i < 2; i++)
        {
            for (int j = 0; j < 2; j++)
            {
                matrix[i, j] = $"Row {i + 1}, Column {j + 1}";
            }
        }
        Console.WriteLine(matrix);
    }
}

Output

System.String[,]
