How to access the inner exception information from .NET exceptions?

Hi,

I am wondering how I can expose the inner exception information within
IronRuby.

My program is throwing an exception only on one user’s computer, the
exception originates in a SelectItem method in WPF
RibbonControlsLibrary, ComboBox.

I am able to catch the exception and log it, by using a begin; (code);
rescue => e; logger.debug [e.class, e.message,
e.backtrace.join("\n")].join(" "); end.

However this seems to only give me superficial information about
exceptions thrown by .NET.
I would like to be able to log all the exception information, incl each
inner exception, so I can evaluate the problem and hopefully solve it.

Is this possible or are there any other suggestions?

Thanks for any help!

This is the current exception output;

Answered my own question after inspecting the exception methods, and the
.NET System.Exception class.
Base/Inner exception seems to be what I was mostly after:
logger.debug [ “#{e.class}: #{e.message}”, “Base
Exception: #{e.GetBaseException}”, “Inner Exception:
#{e.InnerException}”, “StackTrace: #{e.StackTrace}”, “Source:
#{e.Source}”, “TargetSite: #{e.TargetSite}”, “Data:
#{e.Data}”, “BackTrace: #{e.backtrace.join(”\n")}"
].join("\n")
