Returning an ArrayList of string[] in a WebMethod

[scorpicorn]

Working on a web service in VS.net. When trying to return an ArrayList containing objects of type string[], the client call to the webmethod always fail with the following error:

System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: The type System.String[] may not be used in this context.

Does anyone has any idea why is this happening?

Thanks in advance.

Found that adding XmlInclude attribute will resolve the problem.

Thanks
