propagate an exception of a concrete type in Indigo

  Hi,

  You need to annotate your ServiceOperation with a FaultContract. Here are the steps:

  By the way, OperationContract's have to be two-way for SOAP fault to be returned.

  //1.Define a DataContract for your error type

  [DataContract]

  public class MyError

  {

  [DataMember]

  public DataSet ErrorDS;

  }

  //2.Annotate your Operation with a FaultContract

  [ServiceContract]

  public interface IMyService

  {

  [OperationContract]

  [FaultContract(typeof(MyError))]

  int MyOperation(int id);

  }

  //3. In the service implementation when exceptions occur throw a FaultException<MyError>

  MyError me = new MyError();

  me.ErrorDS = ...

  FaultException<MyError> fe = new FaultException<MyError>(me, new FaultReason("Validation failed"));

  throw fe;

  //4. Catch the exception in the cient

  try

  {

  ......

  }

  catch (FaultException<MyError> me)

  {

  String message = String.Format("{0}. No. of Error rows = {1}", me.Message, me.Detail.ErrorDS.Tables[0].Rows.Count);

  MessageBox.Show(message);

  }

  Hth.

  ups, i can not get it working. I have done all what you say, but it gives me that excepcion, i am trying to find in google but I haven't found any solution. I have tested debugging and with release with the same error. Perhaps i have to write something in the config. Do you know any solution

  Thanks

  The exception:

  An error occurred while receiving the HTTP response to http://localhost:8080/ServidorSiliis/Service.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

  Hope your are using the same binding type on both Server and client.

  I would suggest that you try hosting the service in WinForns and see if you can get exceptions working and then host in IIS.

  Also, you could stubb out a simple method and without any implementation throw your custom FaultException<> and see if you can catch it on the client.
