Example 2: c# how to shuffle a list

class Program
{
    static string[] words1 = new string[] { "brown", "jumped", "the", "fox",
                                            "quick" };

    {
        var result = Shuffle(words1);
        foreach (var i in result)
        {
            Console.Write(i + " ");
        }
        Console.ReadKey();
    }

   static string[] Shuffle(string[] wordArray) {
        Random random = new Random();
        for (int i = wordArray.Length - 1; i > 0; i--)
        {
            int swapIndex = random.Next(i + 1);
            string temp = wordArray[i];
            wordArray[i] = wordArray[swapIndex];
            wordArray[swapIndex] = temp;
        }
        return wordArray;
    }
