Detecting faults when using ChannelFactory

I'm trying to detect a faulted channel from the client side without any success. I'm using ChannelFactory<>.CreateChannel(), not a generated proxy. I've tried to handle the Faulted event of the ChannelFactory, but it is never raised. The transparent proxy that is returned from the CreateChannel method doesn't have any events defined.

So the question is, how does one detect a faulted (or otherwise broken) channel when using ChannelFactory<>.CreateChannel()?

Thanks.

How about something like this?

ChannelFactory<IFoo> cf = new ChannelFactory<IFoo>();
IFoo c = cf.CreateChannel();
((IChannel)c).Faulted += new EventHandler(Channel_Faulted);

Thank you, that is exactly what I was missing. I tried to cast the channel to ChannelBase but that didn't work. I didn't try IChannel.

But how do I find out what exception has occurred? (I want to be able to log exceptions in a central place)

Who said an exception occurred? The Faulted event will fire, for example, if someone calls channel.Abort(). There's not necessarily any associated exception.

Hi. How can I convert

((IChannel)c).Faulted += new EventHandler(Channel_Faulted);

in VB.Net?

I tried ctype(c,IChannel). but it doesn't have any events, just a State property and some methods BeginOpen, BeginClose...

What am I doing wrong?

Thanx

Try something like this:

Code Snippet

Dim cf As ChannelFactory(Of IService1) = New ChannelFactory(Of IService1)()
Dim c As IService1 = cf.CreateChannel()
Dim chnl As Channels.IChannel = CType(c, Channels.IChannel)
AddHandler chnl.Faulted, me.myFaultEvent
