Capturing SOAP faults and handling exceptions

Question

I am consuming a web services. Some methods throw exception when i invoked, because the parameters are invalid values, for example. I want to handle the exceptions but it don't contains any data information, only the message "Bad Request". This is my http response:

        try
        {
            var data = client.SomeMethod(4);
        }
        catch (Exception exception)
        {
            // exception.Message = Bad Request
            // exception don't contains any more data information
        }   

How can I capture the other information

You can catch the exception with FaultException when the http status code is 2xx or 5xx, not 4xx. You can catch the http status code 4xx with System.ServiceModel.ProtocolException and then get the stream from the InnerException and parse it or get the FaultException from this stream.
