Copy a 2-dimensional array in C#

This post will discuss how to a copy 2-dimensional array in C#.

A simple and straightforward solution to create a shallow copy of an array is using the Array.Clone() method. Consider the following example, which clones a 2D array of integer type. Note that the clone is of the same type as the source array.

using System;

public class Example

{

public static void Main()

{

int[,] arr =

{

{1, 2, 3},

{4, 5, 6},

{7, 8, 9}

};

// clone the 2D array

int[,] copy = arr.Clone() as int[,];

// print the 2D array

for (int i = 0; i < copy.GetLength(0); i++)

{

for (int j = 0; j < copy.GetLength(1); j++) {

Console.Write("{0} ", copy[i, j]);

}

Console.WriteLine();

}

Output:

1  2  3
4  5  6
7  8  9
