Packet structuring

Example on CharacterCreation.

If you store the structures values like this:

Code:

        public Data<ushort> Size = new Data<ushort>() { Value = 60, Offset = 0 };
        public Data<ushort> Type = new Data<ushort>() { Value = 0x3e9, Offset = 2 };
        public Data<string> Account = new Data<string>() { Offset = 4 };
        public Data<string> CharName = new Data<string>() { Offset = 20 };
        public Data<string> Password = new Data<string>() { Offset = 36 };
        public Data<ushort> Model = new Data<ushort>() { Offset = 52 };
        public Data<ushort> Job = new Data<ushort>() { Offset = 54 };
        public Data<uint> UID = new Data<uint>() { Offset = 56 };

Data struct:

Code:

    public struct Data<T>
    {
        public int Offset;
        public T Value;

        public static implicit operator T(Data<T> data)
        {
            return data.Value;
        }
    }

Then at reading the packet:

Code:

        public static implicit operator CharacterCreationPacket(byte[] Packet)
        {
            CharacterCreationPacket packet = new CharacterCreationPacket(Packet);

            packet.Size.Value = packet.ReadUInt16(packet.Size.Offset);
            packet.Type.Value = packet.ReadUInt16(packet.Type.Offset);
            for (int i = 0; i < 16; i++)
            {
                byte BYTE = packet.ReadByte(packet.Account.Offset + i);
                if (BYTE > 0)
                {
                    packet.Account.Value += Convert.ToChar(BYTE);
                }
            }
            for (int i = 0; i < 16; i++)
            {
                byte BYTE = packet.ReadByte(packet.CharName.Offset + i);
                if (BYTE > 0)
                {
                    packet.CharName.Value += Convert.ToChar(BYTE);
                }
            }
            for (int i = 0; i < 16; i++)
            {
                byte BYTE = packet.ReadByte(packet.Password.Offset + i);
                if (BYTE > 0)
                {
                    packet.Password.Value += Convert.ToChar(BYTE);
                }
            }
            packet.Model.Value = packet.ReadUInt16(packet.Model.Offset);
            packet.Job.Value = packet.ReadUInt16(packet.Job.Offset);
            packet.UID.Value = packet.ReadUInt16(packet.UID.Offset);

            return packet;
        }

Would it have any benefit or it would just slow down everything?
