Hunspell integration error

Question

I have been trying to integrate the NHunspell spell checker API into a unity project that I am currently working on. I have been able to set it up correctly using the code:

void Start()
{
      using (Hunspell hunspell = new Hunspell("Assets/Dictionaries/en_GB-oed.aff", "Assets/Dictionaries/en_GB-oed.dic"))
      {
            bool correct = hunspell.Spell("Recommendation");
            Debug.Log("Recommendation is spelled " + (correct ? "correct" : "not     correct"));
      }
}

but when I press play, I get the following error:

NHunspell Unity Error

The files were downloaded from the Nhunspell website and are in the correct directory location:

AFF/DIC File Location

I understand that the error is caused because it believes the aff file to be null but it isn't. I haven't been able to find anyone with the same problem online and other examples using NHunspell seem to work without any problems using the same code. wherever I put the files in the directory the same error occurs.

If anyone can help me with this, It would be much appreciated.

Can you confirm the stack trace of your exception? From the posted code, it's unclear what's causing it. — Dan Puzey, Aug 04 '14 at 11:10
This is what I recieved: ArgumentNullException: Argument cannot be null. Parameter name: path1 System.IO.Path.Combine (System.String path1, System.String path2) (at /Users/builduser/buildslave/monoAndRuntimeClassLibs/build/mcs/class/corlib/System.IO/Path.cs:138) NHunspell.MarshalHunspellDll.get_NativeDLLPath () NHunspell.MarshalHunspellDll.ReferenceNativeHunspellDll () — Boslem, Aug 04 '14 at 11:12
That looks like a different error to what you think. It's not failing to find your dictionary; it's failing to properly load the Hunspell library. I don't know the library well, but it looks as though you need two DLLs - one managed, and one unmanaged. Do you have both of those in your project? — Dan Puzey, Aug 04 '14 at 11:24
Oh ok, Thanks. I'm not sure as I installed Hunspell using the Nuget package Manager as it was suggested on the Hunspell website.(I don't use API's that are not Unity packages often so I may not understand everything) is there a easy way for me to check? — Boslem, Aug 04 '14 at 11:49
We (the NHunspell) developers will investigate in this issue. This is the post in our support forum: http://www.crawler-lib.net/boards/topic/6/having-implementation-issues — Thomas Maierhofer, Aug 04 '14 at 18:46
Did you find a soltution ? I have the same issue trying using it with Unity3D. I think it is a compatibility problem due to the fact Unity3D is using an old version of .Net through Mono. — Nicolas Hognon, Oct 10 '14 at 09:14
Sadly I did not find a solution and had to write my own Spell checking system — Boslem, Oct 11 '14 at 18:07
