Hi Bhairav, The Microsoft� ADO.NET Framework provides
explicit XML serialization support only for the DataSet object. Just like any other
.NET object, the DataSet object is stored in memory in a binary format. Unlike other
objects, though, the DataSet is always remoted and serialized in a special XML format
called the DiffGram. When the DataSet is sent across an application domain, process,
or machine boundary, it is automatically rendered as a DiffGram. At destination, the
DataSet is silently rebuilt as a binary and usable object�an exact copy of the
original. The same serialization facilities are available to applications through a
bunch of methods, a pair of which clearly stand out: ReadXml and WriteXml
The DataTable, DataRow, DataView, and DataViewManager objects
cannot be serialized and therefore cannot be returned from an XML Web service. To
return less than a complete DataSet, you must copy the data that you want to return to
a new DataSet. It's important that you duplicate the DataTable object for the simple
reason that each ADO.NET object can be referenced only by one container object. You
cannot have the same instance of, say, a DataTable object belonging to two distinct
DataSet objects. For more please have a look th following URL.

Hope this help. Thanks and Regards, Suresh
