Randomize / Randomise an ienumerable collection

ShuffleList.cs

IEnumerable<int> ints;

var random = new Random();
var shuffled = ints.OrderBy(i => random.Next()).ToList();



// or we can avoid risks of using OrderBy by declaring our own
var random = new Random();
var shuffled = ints
      .Select(i => new { key=random.Next(), i })
      .OrderBy(tmp => tmp.key)
      .Select(tmp => tmp.i)
      .ToList();
