Hi all.

I have a problem with returning a custom Result object with
webservice.

The classes i use is described below (some fields and properties is
removed)

public class Result {
int statusCode;
object data;
}

public class Customer {
int customerNr
}

public class CustomerList : ArrayList {
//Implements the add method to only add Customer objects
}

And now to the webmethod

[WebMethod]
[XmlInlude(typeof(Customer))]
[XmlInlude(typeof(CustomerList))]
public Result GetCustomers() {
//Logic to find the customer is placed here....
//All the customers is placed in a variable called custList

res.data = custList;
res.statusCode = 1;

return res;
}

Now, when running this, this errormessage appears:

System.InvalidOperationException: The type Result may not be used in
this context. at System.Xml.Serialization.XmlSerializationWriter.WriteTypedPrimitive(String
name, String ns, Object o, Boolean xsiType) at

System.Web.Services.Protocols.SoapServerProtocol.WriteReturns(Object[]
returnValues, Stream outputStream) at
System.Web.Services.Protocols.WebServiceHandler.WriteReturns(Object[]
returnValues) at System.Web.Services.Protocols.WebServiceHandler.Invoke()

I also get the same error when trying to just return the CustomerList
and skip the Result object but instead the error says:

System.InvalidOperationException: The type CustomerList may not be
used in this context.

Please help!!!
