I do not know if this is going to be useful for you. But I show below an example of how to leave a collection (List, Array) random.

Method Call

public void RandomizarMinhaLista()
{
    List<string> foo = new List<string>();
    foo.Add("foo1");
    foo.Add("foo2");
    foo.Add("foo3");

    var fooRandomizado = foo.Randomize();
    //Ou
    var fooRandomizado2 = RandomizeArray.Randomize(foo);
}

Static class

public static class RandomizeArray
{
    private static Random _random = new Random();
    public static IEnumerable<TModel> Randomize<TModel>(this IEnumerable<TModel> collection)
    {
        List<KeyValuePair<int, TModel>> list = new List<KeyValuePair<int, TModel>>();

        // Insere todos os items da coleção em uma nova lista.
        foreach (TModel s in collection)
        {
            list.Add(new KeyValuePair<int, TModel>(_random.Next(), s));
        }
        // Randomiza a lista
        var sorted = from item in list
                        orderby item.Key
                        select item;

        // Aloca um array de TModel
        TModel[] result = new TModel[collection.ToArray().Length];
        // Copia os valores para o array.
        int index = 0;
        foreach (KeyValuePair<int, TModel> pair in sorted)
        {
            result[index] = pair.Value;
            index++;
        }
        // Retorna array copiado.
        return result;
    }
}
