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")> _
