return and send objects to web service

 Hello everyone
 
Im deploying web service which have some data object,let say that person is a defined object which is an
accept parameter  from one of the servicesmethod,
[webmethod]
public Person[] getAllRelatedPersons(Person ){
}
when Im on the client(web site) I can see the person class and can create instance of it (base on
my wsdl file)
But there is only a default constructor (parameterless).
I would like to be able to watch all his constructor but they actully 'erased'
My prblem is the same with standart method that person include(I cant see them).
 
Let me know what is the standart solution
 
Thanks
Tal
