Question

Here is the webservice:

Custom classes:

public class A
{
    public A()
    {
    }
    public B prop { get; set; } 
}

public class B
{
    public B()
    {
    }
    public A prop { get; set; }
}

Webmethod:

[WebMethod]
[XmlInclude(typeof(A))]
public object Test()
{
    A a = new A();
    a.prop = new B();

    return a;
}

Here is the client side:

Service ws = new Service();
var response = ws.Test();

So, why is the webservice returning XmlNode list instead of class A? How to solve it?

PS: if I comment public A prop { get; set; } line, it works

Answer 1

Ok, found the solution:

I could use a wrapper, like this:

• C#.NET WebService returning object

Or I use the [return:] attribute, like this:

[WebMethod]
[return: XmlElement(typeof(A))]
public object Test()
{
    A a = new A();
    a.prop = new B();

    return a;
}
