c++ how to use __declspec property get & set with a fixed sized array

Question

I am dealing with a struct mf fixed arrays of char, but the size and placement of some of these members depend on other members. so I want to use __declspec(property) to dynamically retrieve these 'variable' members

so Ideally it would look something like this:

struct tVariableRecord
{
    char cRecordType;
    union
    {
        struct
        {
            char cRecordType1_Field1[4];
            char cRecordType1_Filler[6];
            char cRecordType1_Field2[6];
            char cCRLF[2];
        };
        struct
        {
            char cRecordType2_Field1[6];
            char cRecordType2_Field2[6];
            char cCRLF[2];
        };
    }
    __declspec(property(get=get_Field2))   char cField2[6];
    char [6]&get_Field2()
    {
        static char cBadField2[6] = { '#', '#', '#', '#', '#', '#' };
        switch (cRecordType)
        {
            case '1':
                return cRecordType1_Field2;
                break;
            case '2':
                return cRecordType2_Field2;
                break;
            default:
               throw(unknownRecordType);
               return cBadField2;
               break;
         }
    }
};

I know the above won't work, but is there a way to do the same thing?
