Hey,
I have a class with an indexer property, e.g:
public MyClass
{
private ArrayList _list=new ArrayList();

public AnotherType this[int Index]
{
get
{
return (AnotherType)_list[Index];
}
}
}

In my WebService I have a WebMethod returning a MyClass object.
No matter what I tried, the SOAP returned by this WebMethod always
returns an empty _list!
Is there a way to force the XML Serializer to serialize the _list
object?
Thanks ahead

The XmlSerializer can't serialize your classes indexer because it
doesn't know it's a collection (it doesn't implement ICollection). You
could probably implement ICollection (particularly easy in .NET 2.0
thanks to Generics, but I assume you're using .NET 1.x because you're
using ArrayList) but the easiest thing to do is change your class
slightly like so...

public class MyClass
{
private ArrayList _list = new ArrayList();

[XmlArray("MyList"), XmlArrayItem("Item", typeof(AnotherType))]
public ArrayList Items
{
get
{
return _list;
}
}
}

Which serializes to:

<MyClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<MyList>
<Item>test1</Item>
<Item>test2</Item>
</MyList>
</MyClass>

If you're using .NET 2.0, give me a shout and I;ll send the generics
based example. Hope that helps.

Correction - I actually think it's IList the serializer looks for, not
ICollection.
