A New ResultBuffer Class

Opinion needed
I want to write a resbuf wrapper class for my little Intellicad project.
If you were writing one using  .Net 2.0 generics would you use a similar TypedValue structure
or use one of the built-in generic dictionaries I.e


--- Code: ---static Dictionary<int, Object^> ^ToDictionary(resbuf * inl_List)
{
    Dictionary<int, Object^> ^mDict = gcnew Dictionary<int, Object^>();
    //
    for (resbuf * lList=inl_List; lList; lList=lList->rbnext)
    {
        switch ( lList->restype )
        {
        case RTSTR:
            mDict->Add(lList->restype , safe_cast<Object^>(gcnew String(lList->resval.rstring)));
            break;

        case RTSHORT :
            mDict->Add(lList->restype , safe_cast<Object^>(lList->resval.rint));
            break;

        case RTLONG :
            mDict->Add(lList->restype , safe_cast<Object^>(lList->resval.rlong));
            break;

        case RTREAL :
            mDict->Add(lList->restype , safe_cast<Object^>(lList->resval.rreal));
            break;
            //todo add the rest of the types
        }
    }
    return mDict;
}
//
static List<KeyValuePair<int, Object^>> ^ToList(resbuf * inl_List)
{
    List<KeyValuePair<int, Object^>> ^mList = //
        gcnew List<KeyValuePair<int, Object^>>(ToDictionary(inl_List));
    return mList;
}

--- End code ---

Thanks

TonyT:
A dictionary stores a list of key/value pairs with the
constraint that there can be no duplicate keys, which
I think rules it out for the intended purpose.

I would just yank the source for TypedValue from the
Autodesk libraries with reflector and use it with a List<>

Thanks Tony,
I was headed down the wrong path using the Dictionary<>.  :oops:
I was considering using the built-n KeyValuePair<> but opted to make a TypedValue class as you suggested.
Well now the easy part works getting an unmanaged resbuf in a list now I just have to figure out how to do the reverse. 8-)

TonyT:
Marshalling beween resbuf and TypedValue is not exactly
trivial, because some unmanged types have very different
managed representations (namely, unmanaged selection sets
and the managed counterpart are vastly different).

To see how involved it is, have a look at these
methods of the ResultBuffer in reflector:

TypedValueToResbuf()
ResbufToTypedValue()

Not only that, but I will also have to build each of the Types as well, Point2d, Point3d …
Might be biting off more than I can chew. But I am learning tons
