loops - 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 System.Linq you could do...

// List<...> list;
foreach (var i in list.Reverse())
{
}

For a random order you'd have to sort it randomly using list.OrderBy (another Linq extension) and then iterate that ordered list.

var rnd = new Random();
var randomlyOrdered = list.OrderBy(i => rnd.Next());
foreach (var i in randomlyOrdered)
{
}
