    public byte[] PackData(MsgBase msg)

        byte[] protoByte = BitConverter.GetBytes((int)msg.Proto);
        using (var ms = new MemoryStream())
        {
            Serializer.Serialize(ms, msg);
            Debug.Log("serializer msg");
            byte[] data = ms.ToArray();
            byte[] len = BitConverter.GetBytes(data.Length + protoByte.Length);
            return len.Concat(protoByte).Concat(data).ToArray();
        }
    }

出现了send msg is fail : System.InvalidOperationException: Unexpected sub-type: LoginMsg

打了序列化标签 但是不支持LoginMsg的序列化  运行到序列化的代码时 直接跳过
