# NMPUtil(.Net MsgPack Utility)

* https://github.com/msgpack/msgpack/blob/master/spec.md

MsgPackのC#実装。

# History

* 20150601: rename NMPUtil.MsgPack to NMPUtil

# ToDo

* 例外を使うのをやめる

* NuGetに登録する

* UnityのSampleプロジェクト

# UnityMemo

いくつか使えない要素を置き換えた。

* System.Threading.Tasks -> event

* MethodInfo.GetCustomAttributes<> -> GetCustomAttributes

* MethodInfo.CreateDelegate -> Invoke

* ArraySegmentでLINQが効かない件

# 使い方

## Pack

sample

    var ms = new MemoryStream();

    var packer = new MsgPackPacker(ms);

    packer.Pack_Array(4);

    packer.Pack(0);

    packer.Pack(1);

    packer.Pack(false);

    packer.PackNil();

    var bytes = ms.ToArray();

    

## Unpack

sample

    var unpacker = new MsgPackUnpacker(bytes);

    

    var a=unpacker.Unpack();

    

    Assert.AreEqual(4, a.Length);

    Assert.AreEqual(0, a[0]);

    Assert.AreEqual(1, a[1]);

    Assert.False((Boolean)a[2]);

    Assert.AreEqual(null, a[3]);

## Traverse

# 既存の型のPack, Unpack

    // register pack System.Drawing.Color

    MsgPackPacker.AddPack(

        (MsgPackPacker p, Object o) =>

        {

            var color = (System.Drawing.Color)o;

            p.Pack_Array(4);

            p.Pack(color.A);

            p.Pack(color.R);

            p.Pack(color.G);

            p.Pack(color.B);

        });

    MsgPackUnpacker.AddUnpackArray(

        (MsgPackUnpacker u, UInt32 size) =>

        {

            if (size != 4)

            {

                throw new ArgumentException("size");

            }

            var a = u.Unpack();

            var r = u.Unpack();

            var g = u.Unpack();

            var b = u.Unpack();

            return System.Drawing.Color.FromArgb(a, r, g, b);

        });
