Possible to iterate backwards through a foreach?

Question

I know I could use a for statement and achieve the same effect, but can I loop backwards through a foreach loop in C#?

Answer 1

Elaborateling slighty on the nice answer by Jon Skeet, this could be versatile:

public static IEnumerable Directional(this IList items, bool Forwards) {
    if (Forwards) foreach (T item in items) yield return item;
    else for (int i = items.Count-1; 0<=i; i--) yield return items[i];
}

And then use as

foreach (var item in myList.Directional(forwardsCondition)) {
    .
    .
}
