Cannot add python assembly reference for IronPython DLR app

Question

Hello,

I received the following error when attempting to add a reference using Visual Studio for a C# IronPython DLR app:

[A reference to 'NpyAccessLib.dll' could not be added.  Please make sure that the file is accessible, and that it is a valid assembly or COM component.]

The complete path to the dll was omitted.  The assembly is part of Numpy for .NET.  A different assembly was added successfully. 

Any suggestions?

Answer 1

Hi williamj,

the file is a native DLL which means you can't add it to a .NET project via Add Reference...

you can use it via DllImport

see http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx

Sophia:

Thanks for your reply.

How did you know the assembly was native?

And, I am not sure which native methods to implement in managed code.

Regards,

William
