Thanks to all who replied and got me on the right track. I ended up with
something like this:
ULONG size;
PCCOR_SIGNATURE sig = pInternalImport->GetSigOfFieldDef(fd, &size);
SigPointer sigptr(sig);
_ASSERTE(sigptr.GetData() == IMAGE_CEE_CS_CALLCONV_FIELD);
CorElementType corType = (CorElementType)sigptr.GetData();
if (corType == ELEMENT_TYPE_CLASS)
{
mdTypeDef type = sigptr.GetToken();
return IsReferenceCounted(pInternalImport, type);
}
else
return S_FALSE;
Is this a good way of doing it, or are there some caveats here?
