I have a series of numbers saved in an array, ex 4,6,7,8 and I want them to change into a random series, ex 6,8,4,7 or 8,6,4,7 etc. How can I do that?
I prefer in C#
Thanks in advanced

int ShuffleArray(int array)
{
System.Random r = new System.Random();
for (int i = array.Length; i > 0; i–)
{
int j = r.Next(i);
int k = array[j];
array[j] = array[i - 1];
array[i - 1] = k;
}
return array;
}
