Web Service Problem

Hello All

I am having issues with a Web Service. The method I am attempting to construct will return a custom object to the caller. This object implements the IPrincipal Interface. One of the methods of the IPrincipal interfact has the method signature o

IIdentity Identity {get;

The problem I am having is that when I attempt so Serialize the object I get the following exceptio

Cannot serialize member CustomObject.IIDentity because it is an interfac

However, If I attempt to chage the above method to a specific object I violate the interfact contract. I have looked on google a lot over the last couple of days but no luck finding anything. Any help would be appreciated. Thanks

Try modifying your serialization pattern slightly. I haven't used Xml
Serialization in awhile so I may be off a little here.

Instead of trying to serialize the IIDentity Member, expose another member
(possibly protected) that is the actual implementation of IIDentity and
serialize that. For example

public class CustomObject
{
private MyIIDentity identity;

[XmlIgnore()]
public IIDentity Identity
{
get { return identity; }
}

[XmlElement()]
protected MyIIDentity MyIIDentity
{
get { return identity; }
set { identity = value; }
}

/* Rest of code */
}
