Remarks

In a service, use the FaultException class to create an untyped fault to return to the client for debugging purposes.

In a client, catch FaultException objects to handle unknown or generic faults. Because FaultException extends CommunicationException, remember to catch any FaultException objects prior to catching CommunicationException objects if you want to catch them separately.

In general, it is strongly recommended that you use the FaultContractAttribute to design your services to return strongly typed SOAP faults (and not managed exception objects) for all fault cases in which you decide the client requires fault information. However, use the FaultException in the following situations:

  • To send SOAP faults from a service for debugging purposes.

  • To catch SOAP faults on a client when the faults are not part of the service contract.

Throw FaultException objects when you want the string to be passed to the constructor and retrieved by the client by calling the FaultException<TDetail>.ToString method. If you specify a fault contract of type System.ServiceModel.FaultException<TDetail> where one of the parameters is of type System.String, the value of the string is available as the FaultException<TDetail>.Detail property and the FaultException<TDetail>.ToString method need not be called to recover the reason descried in the value.
