亲们我最近在做TcpSocket通讯问题，我在做服务端，有段代码不懂请教一下请大家给具体的解释解释
  private byte[] GetByteData(string strMessage)
        {
            byte[] bytesData = new byte[strMessage.Length];
            for (int i = 0; i < strMessage.Length; i++)
            {
                bytesData[i] = (byte)Convert.ToInt32(strMessage.Substring(i * 2, 2), 16);
            }
            return bytesData;
        }

        private static string GetStringFromBytes(byte[] bytes, int size)
        {
            string strMessage = "";
            for( int i = 0; i < size; i++)
            {
                strMessage += Convert.ToString(bytes[i], 16).ToUpper().PadLeft(2, '0');
            }
            return strMessage;
        }
