The problem is more complex than I wrote here but I will show my solution to this problem. Here is what we had. Class Foo { protected static List<T> list; list = fill_it_up(); // fills the list public class FooIterator : IEnumerator { protected int lastVisited; public FooIterator () { lastVisited = -1; _more enumeration code...._ } The FooIterator was neede by other class to enumerate through the List<>. The inner class was not working because the List has to be static. Class Bar is an object that contains 2 other objects. Here is the change: Class Foo { protected List<Bar> list; list = fill_it_up(); // fills the list public class FooIterator { private List<Bar> list; public FooIterator (List<Bar> anotherList) { list = anotherList; } public IEnumerator<FeFiFoe> GetEnumerator() { foreach (Bar b in list) { // returning the property FeFiFoe object from the Bar object yield return b.thisFeFiFoe; } } } Hope this helps someone else.

I think I figured out why I'm having the problem but I still can not figure a way around it yet. FooIterator in an inner class so it can only acess list if list is a static attribute. So I made changes like so: public object Current { get { return Foo.list[lastVisited].thisBar; } But when checking the degugger, when I load Foo.list is is fine. When I access it via the Iterator inner class it is empty. I tried to get rid of the inner class and return the static list and that did not work. What I need to do is immitate the Java Iterator but this seems impossible because of the static attribute contrate on inner classes.

Tried this but did not work. See following post for why and a new question.

Just tried this and got an InvalidOperationException saying that the enumeration has either not started or finished.

Long time Java programmer running into a C# issue I can not figure out. I have a class that contains a List. Other classes need iterate through the list. What I have below is not working. I get an excpetion at runtime about Current being outofRange. Should I just return an Enumerator from the List or is there a way to do it like this that I'm missing. thanks for the help. Class Foo { List list; list = fill_it_up(); // fills the list public class FooIterator : IEnumerator { protected int lastVisited; public FooIterator () { lastVisited = -1; } #region IEnumerator Members public object Current { get { return list[lastVisited].thisBar; } } public bool MoveNext() { return ++lastVisited < list.Count - 1; } public void Reset() { throw new Exception("The method or operation is not implemented."); } #endregion } } }
