Problem : While invoking the returnAl without the returnMyObject WebMethod
enabled, the operation fails with an invalid Operation exception for the
object MyObject. It suggests that I Soapinclude or XmlInclude for
non-static objects - which I tried.
Can someone please suggest a mechanism to achieve this. The MyObject is
defined in the WSDL I can see that.
The moment I enable the returnMyObject (now the MyObject is defined at a
different level in the WSDL - but same definition) everything is working
fine.
Please Help.
To recreate I suggest u can create a sample WebService and cut-n-paste the
WebMethods and the class defn .. You may need the XMl.Serialization assembly
for SoapInclude ..
Thanks

Here is the sample of the code
Created a small WebService using the wizard. I have removed most of the code
for clarity
using System;
using System.Collections;
using System.Xml.Serialization;
<All relevant using statements ...>
namespace MyCollections
{
public class Service1 : WebService
{
public Service1()
{
}
[WebMehtod]
public string HelloWorld()
{ return "Hello World" ; }
// Uncomment the WebMethod attribute and it will work
// [WebMethod]
[SoapRpc()]
public MyObject returnMyObject()
{
MyObject myo = new MyObject();
myo.a = 1; myo.s = "Sample";
return myo;
}
[WebMethod]
[SoapRpc()]
// [SoapInclude(typeof(MyObject))] // This makes NO
Difference
public ArrayList returnAL()
{
ArrayList myA = new ArrayList();
MyObject myo = new MyObject();
myo.a = 1; myo.s = "SamplefromMethod";
int a = 1;
double d = 2.0;
string st = "Sample String in AL";
myA.Add(a); myA.Add(d); myA.Add(st); // All
these will be returned if myobject is not added ..
// Next line causes the problem
myA.Add(myo);
return myA
}
public class MyObject()
{
public int a;
public string s;
// I even tried the following instead of the above two lines
// int _a; string _s;
// public int a { get { return _a;}; set {_a = value;} }
// public string s { get {return _s;}; set (_s = value ;} }
}
}
}
