split packet and get image bytes

image

hello guys if i send packet with image bytes to server i need to get the only image bytes to convert back to image ...

Client side :

public class Image : Writer, Interfaces.IPacket
{
public byte[] Buffer;
public byte[] ImageBytes;

public Image()
{
}

public void Deserialize(byte[] buffer)
{
Buffer = buffer;
}

public byte[] ToArray()
{
Buffer = new byte[(ImageBytes) + 6];
Writer.WriteUInt16(1003, 0 Buffer);
Writer.WriteUint16((ushort)(Buffer.Length), 2, Buffer);
Writer.WriteBytes(ImageBytes, 4, Buffer);
return Buffer;
}
}

and writeBytes :

public static void WriteBytes(byte[] arg, int offset, byte[] buffer)
    {
        foreach (byte arg2 in arg)
        {
            if (buffer == null)
                return;
            if (offset > buffer.Length - 1)
                return;
            buffer[offset++] = arg2;
        }
    } 

Server Side :

ushort PacketID = BitConverter.UInt16(packet, 0);
ushort Length = BitConverter.UInt16(packet, 2);

so i can get packet id and length from packet ... but how to get image bytes ?
