Why cant datareader be returned from a web services method?

Question Posted / kuldeep kumar


Why cant datareader be returned from a web services method?..

Answer / Azhar Khan

DataReader is not designed to work with data serialization, so it cannot be returned directly from a web service method. Instead, you should use DataTable or List<>. To return the result as JSON, you would need to convert the DataTable or List<> object into a JSON format.
