How to Copy an Array in C# ?

Answer

To copy an array in C#, you can use Array.Copy() method or the Clone() method.

✐ Examples

1 Copying an Array using Array.Copy() Method

In this example,

We create an array named arr1 with elements.
We then create a new array arr2 with the same length as arr1.
We use Array.Copy(arr1, arr2, arr1.Length) to copy the elements of arr1 into arr2.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] arr1 = { 1, 2, 3, 4, 5 };
        int[] arr2 = new int[arr1.Length];
        Array.Copy(arr1, arr2, arr1.Length);
        Console.WriteLine("Array 1: " + string.Join(", ", arr1));
        Console.WriteLine("Array 2 (copy of Array 1): " + string.Join(", ", arr2));
    }
}

Output

Array 1: 1, 2, 3, 4, 5
Array 2 (copy of Array 1): 1, 2, 3, 4, 5

2 Copying an Array using Clone() Method

In this example,

We create an array named arr1 with elements.
We then use arr2 = (int[])arr1.Clone() to create a copy of arr1 into arr2.
The Clone() method creates a shallow copy of the array.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] arr1 = { 1, 2, 3, 4, 5 };
        int[] arr2 = (int[])arr1.Clone();
        Console.WriteLine("Array 1: " + string.Join(", ", arr1));
        Console.WriteLine("Array 2 (copy of Array 1): " + string.Join(", ", arr2));
    }
}

Output

Array 1: 1, 2, 3, 4, 5
Array 2 (copy of Array 1): 1, 2, 3, 4, 5
