  1. Hi,

    ich würde die Shuffle-Funktion ein klein wenig anders gestalten.

    [code]
    public static void Shuffle(T[] array)
    {
    int randvar = rand.Next(array.Length);
    T v;

    for (int count = array.Length; count > 1; count–, randvar = rand.Next(count))
    {
    v = array[randvar];
    array[randvar] = array[count – 1];
    array[count – 1] = v;
    }
    }
    [/code]
