You might need to handle ELEMENT_TYPE_STRING, ELEMENT_TYPE_OBJECT, ELEMENT_TYPE_SZARRAY, etc. Don't know what your intent is.
The best thing is to do whatever MethodTableBuilder::InitializeFieldDescs does. There are encapsulations for checking if a signature element refers to a reference type, and you should use that instead of checking directly for ELEMENT_TYPE_CLASS. -----Original Message----- From: Discussion of the Rotor Shared Source CLI implementation [mailto:[EMAIL PROTECTED] On Behalf Of Arild Fines Sent: Tuesday, May 10, 2005 3:24 PM To: DOTNET-ROTOR@DISCUSS.DEVELOP.COM Subject: Re: [DOTNET-ROTOR] Getting an mdTypeDef for the type of a field Discussion of the Rotor Shared Source CLI implementation wrote: > You need to get the field's signature and decode this signature.

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? -- Arild AnkhSVN: http://ankhsvn.tigris.org Blog: http://ankhsvn.com/blog IRC: irc://irc.freenode.net/ankhsvn "The problem in the world today is communication.
