How to Shuffle an Array in C# ?

Answer

In C#, you can shuffle an array using the Fisher-Yates shuffle algorithm.

✐ Examples

1 Shuffle Array of Integers

In this example,

We have an array named intArray containing integers.
We apply the Fisher-Yates shuffle algorithm to intArray.
We print the shuffled array to demonstrate the shuffling.

C# Program

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        int[] intArray = { 1, 2, 3, 4, 5 };
        Random rng = new Random();
        int n = intArray.Length;
        while (n > 1)
        {
            n--;
            int k = rng.Next(n + 1);
            int value = intArray[k];
            intArray[k] = intArray[n];
            intArray[n] = value;
        }
        Console.WriteLine("Shuffled Array: " + string.Join(" ", intArray));
    }
}

Output

Shuffled Array: 3 5 2 4 1

2 Shuffle Array of Strings

In this example,

We have an array named strArray containing strings.
We apply the Fisher-Yates shuffle algorithm to strArray.
We print the shuffled array to demonstrate the shuffling.

C# Program

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        string[] strArray = { "apple", "banana", "cherry" };
        Random rng = new Random();
        int n = strArray.Length;
        while (n > 1)
        {
            n--;
            int k = rng.Next(n + 1);
            string value = strArray[k];
            strArray[k] = strArray[n];
            strArray[n] = value;
        }
        Console.WriteLine("Shuffled Array: " + string.Join(" ", strArray));
    }
}

Output

Shuffled Array: cherry apple banana
