Question

I’ve created an asp.net web service and am trying to test it using my client. The web method I’m currently testing returns a custom object named GetAllTicketsSinceLastPullDateResult, which contains one ArrayList of custom clsTrip objects, and a custom object called FaultResponse. This is how I’m using my client:

ServiceReference1.ServiceSoapClient myClient = new ServiceReference1.ServiceSoapClient();
        ServiceReference1.GetAllTicketsSinceLastPullDateResult result = new ServiceReference1.GetAllTicketsSinceLastPullDateResult();

        result = myClient.getAllTicketsSinceLastPullDate(myUser);

But I get the following error:

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: The type clsTicket was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically.

I Google the error and most of the answers I find have to do with serializing derived classes. But my clsTicket class is not a derived class. What can be causing this error? How do I use XmlInclude or SoapInclude?

Thanks in advance!

Answer 1

Okay I finally got it to work, I ended up putting the following line:

[XmlInclude(typeof(clsTicket))]

Between [WebMethod] and my method’s definition. So far so good.
