The inner exception (if present) can be accessed via the InnerException property of the “outer” exception:


(This is a .NET feature, not an IronPython specific one.)

There’s also an AggregateException which is used in some cases:

Hi Markus,

Thank you for the reply.
How can I access the inner exception in ironpython?

I tried this:

import clr


import OSGeo.GDAL as gdalc


except System.Exception as e:
    print e.Message

But it raises the same message:

The type initializer for 'OSGeo.GDAL.GdalPINVOKE' threw an exception.

So this is not an inner exception?

Maybe you could try to access the inner exception?
