Question

How do I randomize the order of the files I get out of:

string[] files = Directory.GetFiles("folder");

Thank you! 🙂

Answer 1

One option is to use Random:

Random rng = new Random();

and then:

var randomOrderFiles = files.OrderBy(f => rng.Next());

This isn’t the most efficient method as it takes O(nlogn). If this is a problem for you, better algorithms exist.
