Fisher Yates Shuffle - very useful

Category: .NET

Useful for random stuff:

int[] array = new int[6] {1,2,3,4,5,6};
Console.WriteLine(”BEFORE”);
foreach (int i in array)
{
Console.WriteLine(i.ToString());
}

Random rng = new Random();
int n = array.Length;
while (n > 1)
{
int k = rng.Next(n);
n–;
int temp = array[n];
array[n] = array[k];
array[k] = temp;
}

Console.WriteLine(”AFTER”);
foreach (int i in array)
{
Console.WriteLine(i.ToString());
}

Console.ReadLine();
