have you tried changing sys.path.append("C:/Program Files (x86)/DHI/2016/bin/") to sys.path.append("C:\\Program Files (x86)\\DHI\\2016\\bin") also, just to add, as I also use python with DHI toolbox, and I am assuming it is the case here, you can do it without explicitly setting the path, as when you install DHI tools or MIKE, it creates an environment variable, so you can use something like this sys.path.append(os.path.split(os.path.dirname(os.environ['DHI_MIKE']))[0]) However, to be certain, you can test the output of os.path.split(os.path.dirname(os.environ['DHI_MIKE']))[0] in your python console before using it.

Hello,

I'm using ironpython for a while to operate a .dll library. This works, but I need to use some CPython libraries so I would like to try to integrate de .dll in python 2.7

I installed pythonnet through > pip install pythonnet (Windows 7) installing pythonnet-2.3.0-cp27-cp27m-win_amd64.whl

I proceeded like in ironpython:

import clr import sys sys.path.append("C:/Program Files (x86)/DHI/2016/bin/") clr.AddReference('DHI.Tornado.NET') import TornadoNET

and meanwhile in ironpython it works, in using python with pythonnet I get:

File "Automated.py", line 32, in <module> clr.AddReference('DHI.Tornado.NET') System.IO.FileNotFoundException: Unable to find assembly 'DHI.Tornado.NET '. at Python.Runtime.CLRModule.AddReference(String Name)

DHI.Tornado.NET is a .net 4.0

I read everything I could on previous similar issues, but I haven't been able to solve it. Someone has an idea?

Best regards

I just looked again at your problem and noticed that you have 32-bit .NET API, but using 64-bit CPython. Have you tried loading this .NET DLL from 32-bit and 64-bit IronPython or from 32-bit CPython? On Wed, Jun 21, 2017, 2:36 AM A M wrote:
