Can you enumerate a collection in C# out of order?

Question

Is there a way to use a foreach loop to iterate through a collection backwards or in a completely random order?

Answer 1

Using an IList from the C5 Generic Collection Library, Reverse iteration is a feature, rather than extension:

foreach (var i in list.Reverse())
{
}

As well, you can use the Shuffle() method to get a random ordering:

var listClone = (IList) list.Clone();
listClone.Shuffle();
foreach (var i in listClone)
{
}
