How to use MessagePack in C#?

Question

I read the msgpack-cli quick start documentation.

I also got the C# (CLI) NuGet package (v0.3).

None of the classes (eg BoxingPacker, CompiledPacker or ObjectPacker) mentioned in the official documentation exist in the NuGet package (!!). I'm presuming the documentation has been orphaned.

So does anyone have examples how to serialize/deserialize to/from MessagePack within C#? I'm trying to do this for an object and am interested in the binary nature of the serializer.

Answer 1

To future readers: I'd go with Avro or Protocol Buffers or even Thrift over MessagePack based on these results ...

For the sake of the specific question, the key portions are:

public byte[] Serialize<T>(T thisObj)
{
    var serializer = MessagePackSerializer.Create<T>();

    using (var byteStream = new MemoryStream())
    {
        serializer.Pack(byteStream, thisObj);
        return byteStream.ToArray();
    }
}

public T Deserialize<T>(byte[] bytes)
{
    var serializer = MessagePackSerializer.Create<T>();
    using (var byteStream = new MemoryStream(bytes))
    {
        return serializer.Unpack(byteStream);
    }
}

The entire R&D type project, with results is at https://github.com/sidshetye/SerializersCompare and the specific function calls are here.

I am surprised, nobody understood what the user asked. There are so many nuget packages for msgpack and it's really confusing which one to use and how to include in the projects. Im assuming the user wanted to know how to include msgpack in the .net project just like me.

Install MessagePack for CLI from Nuget packages

and then include like this

using MsgPack.Serialization;

I find an example at: http://www.irisclasson.com/2012/12/17/serializing-and-deserializing-packingunpacking-to-a-file-andor-memorystream-with-messagepack-in-c/ I test it in my code, and send the Byte[] data to another host by zmq. It works.

In the latest versions of msgpack-cli the Create method as in MessagePackSerializer.Create<T>(); is marked as obsolete.

Example usage as given in the project's github page may be:

// Creates serializer.
var serializer = SerializationContext.Default.GetSerializer<T>();
// Pack obj to stream.
serializer.Pack(stream, obj);
// Unpack from stream.
var unpackedObject = serializer.Unpack(stream);

Install the package named MsgPack from NuGet. See the pic here :
