How to import a C# dll to python -

-

i've got third party c# dll has been created in dot net 4.5 , has platform target of x86. import python script , i've started off rob deary's answer here. can't example work. i'm using python version 2.7.6 , attributeerror shown below.

file "c:\python27\lib\ctypes\__init__.py", line 378, in __getattr__     func = self.__getitem__(name) file "c:\python27\lib\ctypes\__init__.py", line 383, in __getitem__     func = self._funcptr((name_or_ordinal, self)) attributeerror: function 'add' not found

please note aware of ironpython , python dot net need working c python. here's sample code generates custom c# library: classlibrary1.dll

using system; using system.runtime.interopservices; using rgiesecke.dllexport;  class test {     [dllexport("add", callingconvention = callingconvention.cdecl)]     public static int testexport(int a, int b)     {         return + b;     } }

and here's python script generates error

import ctypes lib = ctypes.cdll.loadlibrary('classlibrary1.dll') lib.add(3,5)

when use line below, output get. @ least know loading dll, i'm not sure why function can't found. 

>>> lib.__dict__ {'_funcptr': <class 'ctypes._funcptr'>, '_handle': 254476288, '_name': 'classlibrary1.dll'} >>>

any appreciated. thanks

as rgiesecke.dllexport documentation states, need target specific architecture (x86 or x64) when building code. leaving set cpu (the default) not work.
