I am trying to catch a given FaultException on a WCF client. I basically need to extract a inner description from the fault class so that I can then package it in another exception for the upper layers to do whatever.
I've done this successfully a number of time, what makes it different this time is that fault is declared as an array, as you can see from the service reference attribute declared on top of the method that throws the exception:
[System.ServiceModel.FaultContractAttribute(typeof(FaultClass[]), Action = "http://whatever/", Name = "whateverBusinessFault")]
This is my code:
try
{
// call service here
}
catch (FaultException<FaultClass[]> ex)
{
if (ex.Detail != null && ex.Detail.Length > 0)
{
throw new CustomException(ex.Detail[0].description);
}
else
{
throw;
}
}
Problem is Detail (which is an array) is always coming back empty in the code even if I can see the data (description field etc.) in the SOAP response from WCF trace.
So the stuff I need is definitely coming back but for some reason either it doesn't get deserialized or I can't get to it from code.
Any help appreciated!
UPDATE:
Trying with @Darin suggestion but no luck, the string I am extracting from the XmlReader is "/r/n":
var sb = new StringBuilder();
using (XmlReader reader = fault.GetReaderAtDetailContents())
{
while (reader.Read())
sb.AppendLine(reader.ReadOuterXml());
}
var detail = sb.ToString();
Looks like the detail section is not coming up at all!
