如何随机排序IEnumerable <>？

using System;
using System.Collections.Generic;
using System.Linq;

public static class EnumerableExtensions
{
    public static IEnumerable<T> Shuffle<T>(this IEnumerable<T> source)
    {
        Random rng = new Random();
        T[] elements = source.ToArray();
        int n = elements.Length;
        while (n > 1)
        {
            n--;
            int k = rng.Next(n + 1);
            T temp = elements[k];
            elements[k] = elements[n];
            elements[n] = temp;
        }
        return elements;
    }
}

int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
IEnumerable<int> shuffledNumbers = numbers.Shuffle();
foreach (int number in shuffledNumbers)
{
    Console.WriteLine(number);
}
