Return an array instead. ArrayList is a class in .NET that has no meaning
to your interop client (java, perl, C++, VB6).

You could use CollectionBase for passing strongly typed
collections from web services. The proxy class then
converts this to an array.

public class Apples : System.Collections.CollectionBase
{
public void Add(Apple apple)
{
this.InnerList.Add(apple);
}

public Apple this[int index]
{
get { return (Apple ) this.InnerList
[index]; }
set { this.InnerList[index] = value; }
}
}

public class Apple
{
public string countryoforigin;
public string colour;
}
