DataView class in web service

Question

Hi,

I am using dataview class in my web service application and returning dataview's object at last. But it is not running. It shows an error messsage as below-

To be XML serializable, types which inherit from ICollection must have an implementation of Add(System.Data.DataRowView) at all levels of their inheritance hierarchy. System.Data.DataView does not implement Add(System.Data.DataRowView).

Plz. help to solve it.

Thanks.
