[Ironpython-users] PINVOKE exception from loaded .NET assembly

[Markus Schaber]

Hi,

it seems, in your case, it’s not an aggregate exception, so you just need to access the InnerException property (without an „s“ at the end) of your System.Exception

Best regards

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.

Hi,

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

https://msdn.microsoft.com/de-de/library/system.exception.innerexception%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

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

There’s also an AggregateException which is used in some cases:
https://msdn.microsoft.com/de-de/library/system.aggregateexception%28v=vs.110%29.aspx


Grüße,
Markus

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

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?
