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



How to Iterate over a Two Dimensional Array in C# ?

Answer

To iterate over a Two Dimensional Array in C#, you can use nested loops.



✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

  1. We declare and initialize a 2D array of integers named matrix.
  2. We use nested loops to iterate over the rows and columns of the array.
  3. Inside the inner loop, we access and print each element of the array.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[,] matrix = { { 0, 1, 2 }, { 1, 2, 3 }, { 2, 3, 4 } };
        for (int i = 0; i < matrix.GetLength(0); i++)
        {
            for (int j = 0; j < matrix.GetLength(1); j++)
            {
                Console.Write(matrix[i, j] + " ");
            }
            Console.WriteLine();
        }
    }
}

Output

0 1 2 
1 2 3 
2 3 4 

2 Iterating over a 2D Array of Strings

In this example,

  1. We declare and initialize a 2D array of strings named matrix.
  2. We use nested loops to iterate over the rows and columns of the array.
  3. Inside the inner loop, we access and print each element of the array.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[,] matrix = { { "Hello", "World" }, { "C#", "Programming" } };
        for (int i = 0; i < matrix.GetLength(0); i++)
        {
            for (int j = 0; j < matrix.GetLength(1); j++)
            {
                Console.Write(matrix[i, j] + " ");
            }
            Console.WriteLine();
        }
    }
}

Output

Hello World 
C# Programming
