public static IEnumerable<TR> Mapcar<T1, T2, TR>(IEnumerable<T1> lst1, IEnumerable<T2> lst2, Func<T1, T2, TR> func)

    var itor1 = lst1.GetEnumerator();
    var itor2 = lst2.GetEnumerator();
    while (itor1.MoveNext() && itor2.MoveNext())
        yield return func(itor1.Current, itor2.Current);
}

您可能还需要C#中的yield关键字的参考.
