ArrayList.GetEnumerator(x,y) --- how to use?

[Kevin P. Fleming]

ArrayList implements an overload for IEnumerator's GetEnumerator method
as follows:

GetEnumerator(int offset, int count)

However, I can't see a way to take advantage of this, even though I'd
like to... I'd like to be able to use foreach to iterate over a section
of the ArrayList, but can't find any syntax that will work. The obvious:

foreach char ch in arList(0,20)
{
....
}

does not compile at all. Any ideas? Is this only usable if you actually
want the IEnumerator interface for something else besides foreach?

It would be great if C# would support such a syntax.
No You have to go the verbose way:

Enumerator e = array.GetEnumerator(0,20);
while(e.MoveNext())
{
Console.WriteLine(e.Current);
}

but for usage with ArrayList thats plain stupid and slow, better would be
here a normal for loop.
