Thank you.

I am not a programmer myself.
How would either InnerException or AggregateException be used in this case?I tried:try:   
except System.AggregateException as e:
    print "exception: ", e.InnerExceptions  
But that didn't seem to be correct.

Subject: Re: [Ironpython-users] PINVOKE exception from loaded .NET assembly    Hi Markus,

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

I tried this:    import clr clr.AddReferenceToFileAndPath("c:/gdal/gdal2bb/gdal_csharp.dll")    import OSGeo.GDAL as gdalc    try:

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?

> I am trying call a method from loaded .NET assembly in python, but for some reason, I am getting a PINVOKE exception. Is there some way to print what is the reason for that exception? 

Maybe you could try to access the inner exception?
