A quick google query (or even using the help in Visual Studio) for
BadImageFormatException would have told you that you'll get this error
if you try to load non-managed code[1] in a managed code application.
There's nothing wrong (presumably) with the dll itself, only your
attempt to load it in an incorrect manner, solutions to which you're
better off searching for in Microsoft .NET forums.
