Re: Getting an mdTypeDef for the type of a field

You need to get the field's signature and decode this signature. In the
simplest case (public Bar Field) the signature will be:
{CALLCONV_FIELD,E_T_CLASS,<compressed token of Bar>} Or
{CALLCONV_FIELD,E_T_VALUETYPE,<compressed token of Bar>}

For calling convention and element type encoding, see CorHdr.h

For token compression/decompression functions see Cor.h

Thanks,
Serge

No, that seems to give me the mdTypeDef corresponding to the enclosing
type. I.E:

public class Foo
{
   public Bar Field;
}

If I have a mdFieldDef for Field here, calling GetParentToken gives me
the mdTypeDef for Foo, not Bar.

Any other ideas?
