How to determinate whether a value is string or binary about msgpack-cli HOT 4 CLOSED

Hi, @darkl

You can enable 'new protocol' specifying PackerCompatibilityOptions.None to Packer.Create method or SerializationContext.CompatibilityOptions.PackerCompatibilityOptions property. It is intended behavior to interop old bindings. Note that Unpacker always handle bin types.

Hi @yfakariya
Thanks for your response,
I tried your suggestion and I still get String as the underlying type:

Here's the code

MemoryStream stream = new MemoryStream();
Packer packer = Packer.Create(stream, PackerCompatibilityOptions.None);
packer.PackBinary(new byte[16]);
stream.Position = 0;

Unpacker unpacker = Unpacker.Create(stream);
unpacker.Read();
Type type = unpacker.LastReadData.UnderlyingType; // string?

Hi @darkl

I recognized the issue. Unpacker certainly recognize new binary type, but it handles it as raw type. It should always treat binary type as byte[], so I will fix it. Thanks!
