基类的xml序列化问题

Question

I am working on XML serialization, and very new for that. (C#.net winform application)

I have stuck in one scenario. My client has given my one class library file and he suggests to use it by overriding in my class.

So i have made below things.

[Serializable]
public class PipeXML : PackPro.CommonLibrary.Pipe
{
    public PipeXML() { }
}

Now, I want to write XML for that using XML serializer, his lib does not contains any XML supported things like Serializable or XMLAttribute, XMLElement tags in it.

Now, when I try to serialize that, i am getting below error.

"The type ClassLib.BusinessObjects.PipeXML was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically."

Does any one having idea, how can I serialize my class and write XML now.
