still having problem return arraylist of objects in webservice....

[Milsnips]

hi there,

i have a webservice which my function calls a database( eg. customer table),
what i have is my own Customer class, and i want to return an array of my
"Customer" objects.

here is my code i use (c.GetList returns an arraylist of customer objects
from the database:


<WebMethod()> _
Function GetClientList() As <XmlElement(GetType(getAway.Client))> ArrayList
Dim c As New getAway.Client
Dim a As ArrayList = c.GetList(False)
Return a
End Function

i still get the same error below:

System.InvalidOperationException: There was an error generating the XML
document. ---> System.InvalidOperationException: The type getAway.Client was
not expected. Use the XmlInclude or SoapInclude attribute to specify types
that are not known statically.

any help appreciated...

Paul.

use XmlInclude or
XmlArray and XmlArrayItem attributes to specify that type. eg


<XmlArrayItem(ElementName := "item", Type:= GetType(getAway.Client)) , _
XmlArray(ElementName := "stuff")> _

I am ruuning into a similar problem. Even XmlInclude does
not seem to work.
My webservice method ( calls Author.GetAuthors() to build
and return an IList of authors.
The webservice method is defined as:
[WebMethod]
public IList GetAllAuthors()
{
Author author=new Author();
return author.GetAuthors();
The Author class is defined in a separate class library
called AuthPubsDAL. Author.GetAuthors() is defined as
public IList GetAuthors()
{
...}
which accesses the pubs database and builds an arraylist
of author objects.

I added [XmlInclude (typeof(Author))] to the webservice
class, to the Author class and to the WebMethod
GetAllAuthors() which is part of the webservice class
with no luck. I am not sure as to what's the proper use
of XmlInclude and where it should be added. Please help.
