Question

Suppose I have a list:-

var animals = new[] {"ant", "bear", "bee", ...... "monkey", ...... "zebra"};

what is the easiest way to iterate between bee and monkey?

Answer 1

after much gnashing of teeth, hair pulling and banging my head against the wall, I decided to do it the easy way of creating my own iterator.

public static class LinqExtensions {
    public static IEnumerable<T> InRange<T>(this IEnumerable<T> list, T first, T last) {
        int i = 0;

        while (list.Count() > i && ! list.ElementAt(i).Equals(first))
            ++i;

        while (list.Count() > i && ! list.ElementAt(i).Equals(last))
            yield return list.ElementAt(i);

        if (list.Count() > i && list.ElementAt(i).Equals(last))
            yield return list.ElementAt(i);
     }
}

now the following works perfectly:-

foreach (var x in animals.InRange("bee", "monkey")) {
    ....
}
