Set IncludeExceptionDetailInFaults to true in code for WCF
How do I开发者_运维百科 set IncludeExceptionDetailInFaults in code without using App.Config?
Yes, sure - on the server side, before you open the service host. This would however require that you self-host the WCF service - won't work in IIS hosting scenarios:
ServiceHost host = new ServiceHost(typeof(MyWCFService));
ServiceDebugBehavior debug = host.Description.Behaviors.Find<ServiceDebugBehavior>();
// if not found - add behavior with setting turned on
if (debug == null)
{
host.Description.Behaviors.Add(
new ServiceDebugBehavior() { IncludeExceptionDetailInFaults = true });
}
else
{
// make sure setting is turned ON
if (!debug.IncludeExceptionDetailInFaults)
{
debug.IncludeExceptionDetailInFaults = true;
}
}
host.Open();
If you need to do the same thing in IIS hosting, you'll have to create your own custom MyServiceHost
descendant and a suitable MyServiceHostFactory
that would instantiate such a custom service host, and reference this custom service host factory in your *.svc file.
You can also set it in the [ServiceBehavior] tag above your class declaration that inherits the interface
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class MyClass:IMyService
{
...
}
