Question

我正在为WCF ChannelFactory Manager编写一些代码。我的问题来自事件“ChannelFactory.Faulted”：两个参数（“对象发送者”和“EventArgs args”）都不包含有关原始fualt的信息，如何在自定义故障处理程序中获取ChannelFactory Fault详细信息？

   private ChannelFactory CreateFactoryInstance<T>(string endpointConfigurationName, string endpointAddress)
    {
        ChannelFactory factory = null;
        factory = new ChannelFactory<T>(endpointConfigurationName, new EndpointAddress(endpointAddress));
        //Customizing Factory Fault handler
        factory.Faulted += FactoryFaulted;
        factory.Open();
        return factory;
    }

    private void FactoryFaulted(object sender, EventArgs args)
    {
        ChannelFactory factory = (ChannelFactory)sender;            
        factory.Close();
        //...
        //How can I get more Fault detail, so as to throw a meaningful Exception?
        throw new ApplicationException("Failure in ChannelFactory ");
    }

感谢您的关注。

我简要介绍了ILSpy，ChannelFactory派生自CommunicationObject，当Open / BeginOpen期间抛出异常时，Open会转换为故障状态。因此，Faulted周围的try / catch将至少捕获一些可能的错误。不确定是否有其他地方通道工厂可能进入故障状态。请注意，在finally块中调用{{1}}事件处理程序，这意味着在捕获异常之前调用它。
