FANN Forum

Hi all,

I am currently in the process of developing a C# .Net wrapper for Fann that interfaces directly with the C/C++ layer and does not require the SOAP web service. If anyone is interested in getting a first look please let me know and I'll send it over to them.

Regards,

James

Sounds like a very good idea, I would be happy to take a look at it.

Hi Steffen,

I'll get it stable over the next couple of days and give you an FTP link to the source.

Thanks,

James

I'm trying to make a more .Net oriented version than Mr Stagg's that reflects the fann_cpp classes as closely as possible. Sorry for the delay, I hope to get the first cut out this weekend.

Regards,

James

Here's my initial alpha cut.

See attached file

Just unzip into your fann 2.1.0 folder and navigate into the Fann.Net folder for the solution. You will need to get a copy of the boost library and set your include path to point at it in order to build. Also make sure that you build Double MultiThreaded projects in the existing MicrosoftWindowsDll project as Fann.Net requires these libs.

At the moment Callbacks are not implemented because of a strange crash that occurs ( if anyone has any clues as to what this may be then please let me know).

My contact details are at the top of the source files, feel free to get in touch if you have any questions or ideas.

Have fun.

James

Dear all,

Please find attached my very crude (rushed) .net interface to the FANN dll. Very basic functionality at the moment and the code is messy with sparse comments. I'll probably only update as I need, but will post here. I also apologise for duplicating the assembly name fannDotNet - I wasn't feeling very imaginative! The zip file includes my VS2005 C# source and some C# code for testing the xor dataset. There is also a MatLab script included (fann.m) that uses the library. It's hiding in the test code debug directory.


Cheers,

Pete

Hey,

When runing your Xor test I get the followin error:

{"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.":null}

I'm using VS 2010 Express

Hi,

You will either need to set your project to build using the the .Net 2 framework or rebuild the wrapper in .Net 4.

Regards,

James

Hey James,

Thanks for the reply... I solved it with a configuration file

About the callbacks, any idea what is causing the problems?

Glad you got it working.

Sorry I haven't had chance to look into the callback issue because I have been bogged down with the stuff that pays the bills.

Regards,

James

Got the callbacks fixed please see the latest version.

Where can we get the latest version?

Thanks.

Will there be an updated version of the code?

My app uses the .Net 4 framework so I was using the wrapper rebuilt in .Net 4.
