WCF Error Handler Exception Logging

I use IErrorHandler in my project for handle exceptions.

But how can i log incoming method parameter with exception. I want to get Request parameter for logging.

Sample Method:

public Re开发者_如何转开发sponse GetData(Request request) {
    return new Response();
}

You could get the request message like this:

Message requestMessage = OperationContext.Current.RequestContext.RequestMessage;

What I do usually is to log the entire request XML.

You don't have such information in IErrorHandler - you can only parse raw message in ProvideFault method.

You can try to use another approach - implement custom IOperationInvoker and in Invoke method do something like:

// Just synchronous implementation - for asynchronous handle InvokeBegin and InvokeEnd
public object Invoke(object instance, object[] inputs, out object[] outputs)
{
  try
  {
    // Run common invoker - you will create new Invoker as decorator for existing one.
    return innerInvoker.Invoke(instance, inputs, outputs);
  }
  catch(Exception e)
  {
    // Handle error here
  }
}

Operation invoker is responsible for selection correct operation in service and ivoke it. It is just idea - I haven't tested it.

Two ways:

1. The native WCF logger will capture all requests & responses when set to verbose however, these files tend to get real big, real quick.

2. Use log4net (search google to download)

   private static readonly ILog log = LogManager.GetLogger(typeof(MyClass));

   public class MyClass
   

   { ...

   public Foo DoSomething(string arg)
   {
       try
       {
          //do something
       }
       catch(Exception e)
       {
          log.error(string.format("{0} Arguements: {1}", e.Tostring(), arg);
       }
   }
   

   }
