AnswerImporting a COM type library and adding a few enums

    Hello, I'm about to create an assembly which contains a converted COM type library, but I'd like to add a few enums on the way. Can I do that? This is the way I've tried so far:

    Object typeLib;

    LoadTypeLibEx(dllPath, RegKind.RegKind_None, out typeLib);

    FileStream fs = new FileStream(@"key.snk", FileMode.Open, FileAccess.Read);

    StrongNameKeyPair keyPair = new StrongNameKeyPair(fs);

    TypeLibConverter converter = new TypeLibConverter();

    ConversionEventHandler eventHandler = new ConversionEventHandler();

    AssemblyBuilder assembly = converter.ConvertTypeLibToAssembly(typeLib, "NewAssembly.dll", TypeLibImporterFlags.PrimaryInteropAssembly, eventHandler, null, keyPair, "NewNamespace", null);

    ModuleBuilder module = assembly.DefineDynamicModule("TempModule", "NewAssembly.dll", true);

    The problem is that I get an ArgumentException "Duplicate file names." when running DefineDynamicModule.

    How can I add enums to my converted COM type library?

    Have you tried using GetModule instead of DefineDynamicModule?

    GetModule returns a Module instead of a ModuleBuilder, so its not really what I'm looking for. Also, the docs for AssemblyBuilder says:

    "Some methods on the base class Assembly such as GetModules and GetLoadedModules will not work correctly when called AssemblyBuilder objects. You can load the defined dynamic assembly and call the methods on the loaded assembly. For example, to ensure that resource modules are included in the returned module list, call GetModules on the loaded Assembly object."

    I'm not quite sure what about GetModules thats not working, but I'm not using it :)

    Right, but you may be able to cast it to a ModuleBuilder.

    It worked. Scary.
