I've base classed it and used reflection so that it can cover more than one object. It works on User, but I also have Transactions (purchases), + a lot of other Dto objects. So long as all of my Dto objects inherit from this BaseDto, I have a ToString method that will enumerate through all of the properties. You're absolutely right - if I'd just been dealing with one object (User) then coming up with something specific would have been more elegant, faster, and avoided the use of reflection, though I needed something generic that could handle pretty much any of my Dto objects (I have about 30) and output it in a useful format, hence the reflection and the base classing. Hope that helps. Cheers, Terry hey Ryan,

Is there any reason why you couldn't just keep things simpler by passing the user object to the exception object and have the exception parse the user object and populate the Data of the exception? This would reduce complexity and remove the need for reflection. Ryan Hi Terry,

Of course this may be the crux of your problem: that these CRLFs are being "normalised" out of the form field. In any case use Fiddler to see what's really going back and forth: espcecially in the POST to the 3rd party service.

My hope is with these, they're only really called when something has gone wrong (system exceptions as opposed to business exceptions) so they should hopefully only be hit ~100-200 times per day (on a 70k visitor count). We're in the process of setting up a dev environment that we can simulate hits on, so I'll hopefully blog about the outcomes of that with the new infrastructure soon! Cheers :) hey mate,

I know from your previous post you were bothered about performance, does reflection have much of a hit on what your doing? Thanks Tim Hi Tez,
