Exceptions are technology specific. Hence they cannot cross
service boundaries. Soap represent standard for errors.WCF can transfer error
from service to client through faults. If the error is a fault Exception then
all the details are transferred else only generic fault.
i.e. InternalServiceFault
we can use either [ServiceBehavior] or to
enable Fault.
Example:-
<serviceBehaviors>
<behavior>
<serviceMetadata
httpGetEnabled="true"/>
<serviceDebug
includeExceptionDetailInFaults="True"/>
behavior>
serviceBehaviors>
You can throw a Soap Fault using the FaultException class
You can specify the fault code and reason when you create it.
All this details will be traveled to the client side.
Example:-
Throw New FaultException(Of
FaultExceptionClass)(New FaultExceptionClass)
At the client side we can use the try catch block to catch this
faultException
Example:- Catch ex As FaultException(Of
FaultService.FaultExceptionClass)
Console.WriteLine("Fault value " + ex.Detail.m_Reason)
Console.WriteLine("Fault value " +
ex.Detail.m_InnerReason)
Example:-
