Subject: Re: [Ironpython-users] PINVOKE exception from loaded .NET assembly    Thank you.

I am not a programmer myself.
How would either InnerException or AggregateException be used in this case? I tried: try:   
 gdalc.Gdal.AllRegister()
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:
    gdalc.Gdal.AllRegister()

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?       Regards,
Djordje   From: Markus Schaber <m.schaber at codesys.com>

Hello,

From: Djordje    

> 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?

Best regards
