Reverse Binding not allowed

[mganss]

I have the following class definition:

class Demo
{
    [FieldOrder(0)]
    public uint BodyCrc { get; set; }

    [FieldOrder(1)]
    [FieldCrc32(nameof(BodyCrc))]
    public uint Body { get; set; }
}

When trying to serialize I get

InvalidOperationException: Reverse binding not allowed on FieldValue attributes. Consider swapping source and target.

The file format I'm trying to serialize demands BodyCrc to come before Body. Is there an elegant way to do this?

Unfortunately no. The nature of the "serializer" is that one thing follows after the other. Recommend firing whomever wrote the format 😉

The pattern is part of the import/export format for a device from a big electronic equipment manufacturer. No docs of course, had to reverse engineer it 🙄
